Description

The present invention relates to a driving support system that supports the driving of a vehicle by providing information on various traffic monitoring activities such as traffic control and inspection.

Conventionally, as a driving support system for supporting the driving of a vehicle, an in-vehicle device such as a radar detector that warns when a radar wave of speed control is received and calls the driver's attention has been realized. Such an in-vehicle device has a GPS function for positioning the current position of the vehicle and a database of GPS contents such as an installation point of a speed control system, and detects approach to a specific GPS content. There is also a device for notifying the driver to that effect (see, for example, Patent Document 1).

As GPS content that the above-mentioned in-vehicle device notifies the approach, in addition to the installation point of the speed control system and the permanent point such as the police station, traffic monitoring activities such as speed control by mobile orbis and drinking inspection are frequently carried out. There are temporary points to be done. The in-vehicle device is trying to draw the driver's attention to traffic safety by notifying the approach to various GPS contents.

However, the conventional driving support system has the following problems. That is, unlike the permanent point where the notification target always exists, it is unclear whether or not the traffic monitoring activity is currently being performed at the temporary point even if the approach to the temporary point is notified, and it is based on the notification content. There is a problem that the driver must judge the degree of risk individually.

The present invention has been made in view of the above-mentioned conventional problems, and is a system for supporting driving by providing information on various traffic monitoring activities such as traffic control and inspection, and driving support with enhanced real-time performance. It is an invention that seeks to provide a system.

In one aspect of the present invention, it is possible to post information including type information indicating the type of traffic monitoring activity carried out to promote traffic safety and position information indicating the monitoring position where the traffic monitoring activity is performed. Posting terminal and
A server that generates and distributes distribution information including type information and location information related to traffic monitoring activities by integrating multiple posting information that has common traffic monitoring activities to be posted among the posted information from multiple posting terminals. With the equipment
It is in a driving support information distribution system including a notification terminal that acquires and notifies distribution information distributed from a server device.

One aspect of the present invention is capable of posting information including type information indicating the type of traffic monitoring activity carried out to promote traffic safety and position information indicating the monitoring position, and is another aspect of the present invention. It is in the posting terminal that constitutes the driving support information distribution system that forms the aspect.

One aspect of the present invention is capable of acquiring and notifying distribution information including type information of traffic monitoring activity carried out for promoting traffic safety and position information of a monitoring position, and another aspect of the present invention can be used. It is located in the notification terminal that constitutes the driving support information distribution system.

One aspect of the present invention is a program for causing a computer to execute.
It is in the notification program for realizing the function of the notification terminal which forms another aspect of the present invention.

By using the posting terminal according to the present invention, it is possible to generate type information indicating the type of traffic monitoring activity carried out to promote traffic safety and posting information including position information indicating the monitoring position for the server device. Can be posted. The server device integrates a plurality of posted information that is common to the traffic monitoring activities to be posted, and generates distribution information including type information and location information related to the traffic monitoring activities. The notification terminal can notify the distribution information distributed from the server device.

While the distribution information can be, for example, highly real-time information generated based on the posted information, the accuracy of the posted information varies, and there may be correct information or incorrect information. If a plurality of posted information whose authenticity is uncertain is delivered as it is in this way, there is a risk of confusion as to which information should be believed on the notification terminal side. In particular, if the notification terminal is installed in the vehicle, or if a portable notification terminal is brought into the vehicle, for example, if such posted information is delivered as it is while the driver is driving, it will hinder driving. There is a risk of becoming.

On the other hand, the distribution information in the present invention may be, for example, information whose accuracy has been improved by integrating a plurality of posted information. In this distribution information, for example, real-time performance based on posted information and accuracy improved by information integration are compatible. Distribution information that has both real-time performance and accuracy can be useful information for the driver.

As described above, the present invention is a system that supports driving by providing information on traffic monitoring activities such as traffic control and inspection, and is a useful invention for realizing a driving support system with improved real-time performance. ..

Traffic monitoring activities subject to the posted information in the present invention include traffic control such as speed control, parking prohibition control, and seatbelt control, and inspections such as drinking inspection and seatbelt inspection.
The server device in the present invention may have both a function of receiving the posted information and a function of transmitting the delivered information, and the server that receives the posted information and the server that receives the delivered information. The server may be connected to the server by a dedicated line, a dedicated communication line, a public communication line, or the like.

The server device in the driving support system of one preferred aspect of the present invention shares a plurality of posted information in which the time for posting the posted information is within a predetermined time and the monitoring position belongs within a predetermined range. Treat as posted information for traffic monitoring activities.

The time related to the posting of the posted information may be the time when the posted information was generated, the time when the posted information was posted, the time when the traffic monitoring activity related to the posted information was witnessed, or the like. By combining the temporal proximity that the time related to the posting is within a predetermined time and the locational proximity that the monitoring position belongs to a predetermined range, the same traffic monitoring activity can be performed. The target post information can be extracted with high accuracy, and the delivery information with high accuracy can be generated. The time when the posted information was generated and the time when the target traffic monitoring activity was witnessed need to be specified on the posting terminal side. Regarding the posted time, the time when the posted information is transmitted may be specified on the posting terminal side, or the time when the posted information is received may be specified on the server device side. When the time specified on the posting terminal side is used on the server device side, it is preferable to include the time information indicating the time in the posting information.

The position information indicating the monitoring position in the driving system of the preferred aspect of the present invention is information that can specify the traveling direction of the vehicle targeted by the traffic monitoring activity in addition to the monitoring position where the traffic monitoring activity is performed. be.
Except for one-way roads, roads in which vehicles can travel in both directions in opposite directions are common. And, some of the traffic monitoring activities carried out on the road, for example, road speed control and inspection, target only one direction of travel. If the distribution information can specify the direction of travel targeted by the traffic monitoring activity, it will be more useful for the driver who is driving on the road where the traffic monitoring activity is performed. This is because the importance of the distributed information is completely different depending on whether the driver is traveling in the direction of travel targeted by the traffic monitoring activity or the driver traveling in the opposite direction. be.

The server device in the driving support system of one preferred aspect of the present invention evaluates the accuracy, which is the degree of accuracy of the posted information, and responds to the accuracy in integrating a plurality of posted information to generate the distributed information. Change the handling of each posted information.
The handling of posted information according to the accuracy includes the following examples. For example, the distribution information is generated by using only the posted information having a certain accuracy or higher. For example, post information that does not meet a certain degree of accuracy is treated as one post information when a plurality of similar post information are posted. For example, posts of the same type within a radius of 100 m are considered to be one post.

The server device in the driving support system of the preferred aspect of the present invention evaluates the accuracy of the corresponding posted information according to whether or not the poster of the posted information can be identified and the posting record of the poster. do.
In general, it is possible to estimate that the information posted by a specific person is more accurate than the information posted by an unspecified person. For a specific contributor, it is also good to make points such as the number of times that correct posted information is posted, and use those points when evaluating the accuracy of the posted information by that specific contributor.

As the posting terminal in the driving line-of-sight system of the preferred aspect of the present invention, various application programs including a dedicated machine in which the posting function of the posting information is incorporated in advance and an application program for incorporating the posting function of the posting information are included. There is a general-purpose machine that the user can select and install.
The server device evaluates the accuracy of the posted information according to whether the posted information is information posted from a dedicated machine or information posted from a general-purpose machine.

The introduction cost on the user side for using the posting function and the degree of expectation for the distribution information differ between the dedicated machine and the general-purpose machine. For example, when the application program of a general-purpose machine is free software or the like, a user who is not so interested in the distribution information may post it by mischief. On the other hand, considering that the dedicated machine is purchased, it can be estimated that the poster from the dedicated machine has a feeling of expectation for the distribution information. For this reason, for example, when the degree of detail of the posted information itself, the quality of the information, etc. are almost the same, the accuracy of the posted information by the dedicated machine is evaluated higher than the posted information by the general-purpose machine. good.

The server device in the driving support system of the preferred aspect of the present invention evaluates the accuracy of the posted information with reference to the information regarding the implementation status of the past traffic monitoring activities.
For example, if posted information on speed control is posted at a point where speed control by mobile orbis is frequently performed, the accuracy of the posted information can be highly evaluated. On the other hand, if posted information on speed control is posted at a point where speed control by mobile orbis has never been carried out, first of all, the accuracy of the posted information is evaluated low, while similar posted information. It is also good to review the evaluation of the accuracy of the first posted information when multiple posts are posted.
The information regarding the implementation status of the past traffic monitoring activity may be, for example, the implementation history of the past traffic monitoring activity or the ready-made traffic information stored in advance regarding the traffic monitoring activity. In particular, the ready-made traffic information that the in-vehicle device such as the radar detector has already accumulated regardless of the posted information may be used as the information regarding the implementation status of the past traffic monitoring activities. Further, the information obtained by adding the past posted information to the already accumulated existing traffic information may be used as "information on the implementation status of the past traffic monitoring activities".

In the server device in the driving system of the preferred embodiment of the present invention, the posting of the posted information is handled depending on whether the posted information is received before or after the delivery of the corresponding traffic monitoring activity. Is different.
Before distribution, for any poster, the traffic monitoring activity to be posted suddenly appears, and it is necessary to judge the type etc. in a short time until it passes. There is a tendency for the registration operation of the point of traffic monitoring activity to be performed after passing the point, and the point actually registered may be shifted forward in the direction of travel from the actual point. On the other hand, after distribution, it is known in advance that the type of traffic monitoring activity related to the distribution information is being performed, so whether the type of traffic monitoring activity actually being performed is the same as the distribution information. The accuracy of the judgment of whether or not it tends to be high. In addition, since you will be approaching the point while having a high interest in whether or not the traffic monitoring activity is actually being carried out at the point related to the distribution information, the registered point tends to be exactly the actual point. .. Alternatively, a quick contributor may shift to the front side of the actual point. If the posted information after the distribution of the distribution information is handled in consideration of such circumstances, the accuracy of the distribution information including the position accuracy can be improved.

The server device in the driving support system of the preferred aspect of the present invention determines whether or not to deliver the delivery information and the delivery time to continue the delivery according to the type of traffic monitoring activity.
For example, traffic monitoring activities such as speed control for mobile orbis have a known duration and are not continued for 24 hours. Based on such knowledge, it is better to determine the delivery time of the delivery information.
On the other hand, for information on fixed speed control, N system, etc., there is a tendency that accuracy close to 100% is required rather than real-time performance. Therefore, regarding the posted information for fixed speed control and N system, rather than immediately distributing the distribution information upon reception, the staff of the system operator goes to the site and visually checks it. It is also good to provide it to the user as confirmed information.

The posting terminal in the driving support system of the preferred aspect of the present invention can post cancellation information to the effect that the traffic monitoring activity corresponding to the distribution information has not been carried out.
The server device evaluates the accuracy of the posted cancellation information, and determines whether or not to terminate the distribution of the corresponding distribution information according to the accuracy.
If the posting of the cancellation information is accepted, the distribution can be terminated as soon as possible after the corresponding traffic monitoring activity is completed. It is possible to suppress the situation in which the corresponding distribution information continues to be distributed in the shortest possible time even though the target traffic monitoring activity is not performed. Further, the cancellation information is useful for stopping the distribution of erroneous distribution information based on the fake posting information at an early stage, or for giving a negative evaluation to the poster of the fake posting information.

When the server device in the driving support system of the preferred aspect of the present invention receives the posting of the cancellation information and then distributes the distribution information regarding the corresponding traffic monitoring activity, it means that the cancellation information has been posted. Information is included in the distribution information.
On the user side, when determining the accuracy of the distribution information, the determination can be made in consideration of whether or not the cancellation information has been posted. The fact that the corresponding traffic monitoring activity is not carried out is the biggest factor that impairs the user's sense of trust in the distributed information. When distributing the distribution information, if the fact that the cancellation information has been posted is also notified, even if the corresponding traffic monitoring activity is not carried out, the damage of the user's confidence in the distribution information is minimized. Can be suppressed close to. The information indicating that the cancellation information has been posted may be, for example, information indicating whether or not the cancellation information has been posted in the integrated posting information. In particular, it is preferable that the information indicates the number of posts of cancellation information. For example, it is advisable to distribute the number of posts of integrated post information and the number of posts of cancellation information among the number of posts.

The posting terminal of one preferred aspect of the present invention is provided with means for generating posting information having a different degree of detail of the type information according to the knowledge level of the traffic monitoring activity on the user side.
For example, when the target traffic monitoring activity is speed control, the types include mousetrap, mobile orbis, and tracking. Further, for example, in the case of mobile orbis, there are types such as radar type, stealth type, and phototube type. Any user who has a deep interest in traffic monitoring activities such as speed control and can recognize the type of equipment or equipment at a glance can post detailed information. On the other hand, for users who can recognize that it is a traffic monitoring activity related to speed violations, but who have little knowledge about speed measurement, requesting detailed information when posting makes the posting itself difficult and may hesitate to post. high. Therefore, while users who have knowledge of traffic monitoring activities can generate detailed posted information, if users who do not have it can post information with a degree of detail such as speed control, it will be posted by various users. Can be promoted. If the amount of posted information that is the source of information increases, the real-time property and accuracy of the delivered information can be improved.

The posting terminal of one preferred aspect of the present invention can acquire the current position, and the posted information is combined with the acquired position information based on the acquired current position with the type information generated by the user's operation. To generate.
In this case, the accuracy of the position information included in the posted information can be improved. Examples of the configuration in which the current position can be acquired include a configuration having a positioning function by GPS and a configuration in which information on the current position is acquired from an external terminal having a GPS function.

The posting terminal of a preferred aspect of the present invention is a first terminal capable of generating the posting information according to an operation on the user side, and a posting information acquired from the first terminal and directed toward the server device. It is composed of a combination of a second terminal for transmission and.
The first terminal is a terminal capable of acquiring the current position and displaying a code image in which the posted information is recorded.
The second terminal may be a terminal capable of capturing a code image displayed by the first terminal and reading the recorded posted information.
As the second terminal, a mobile terminal such as a smartphone having a camera function (multifunctional mobile terminal) or a game machine having a camera function and a communication function can be used. On the first terminal side, it is only necessary to display the code image in which the posted information is recorded. Such a first terminal can be sufficiently realized by a display screen of about 3 to 4 inches or a hardware configuration provided in an existing radar detector having a GPS function.

The posting terminal of one preferred aspect of the present invention can display a map of a predetermined area including a point of interest, and can register the point of interest as a specific point by an operation on the user side.
The posted information is generated by associating the type of traffic monitoring activity selected by the operation on the user side with the position information representing the specific point registered in advance.
If it is on the displayed map, a specific point can be registered with high position accuracy. The posted information generated via the registration of such a specific point is highly accurate information with high positional accuracy.

The posting terminal of one preferred aspect of the present invention can acquire the current position, and the current position is set as the point of interest.
In this case, when passing the point of traffic monitoring activity, that is, when the current position is located in the immediate vicinity of the point, if the registration operation of the specific point is performed, the point of traffic monitoring activity can be easily and located. You can register with high accuracy.

The notification terminal of one preferred aspect of the present invention can acquire the current position and the current time, and selects which of the acquired distribution information is to be notified according to the current position and the current time.
In this case, it is possible to notify appropriate distribution information according to the driving situation. For example, even if the distribution information of the traffic monitoring activity at a point far away from the user's current position and whether or not he / she is heading is notified, the information is of low value to the user. On the other hand, the distribution information regarding the traffic monitoring activity carried out in the vicinity of the user's current position is highly valuable information for the user, so it is better to notify the user. Further, it is preferable to provide a navigation function and notify the traffic monitoring activity of the point on the route calculated by the route calculation function at an early stage when the distance is long.

The distribution information acquired by the notification terminal of a preferred embodiment of the present invention includes accuracy information indicating the accuracy of the distribution information.
The notification mode is changed according to the accuracy of the acquired distribution information.
If the notification mode is changed according to the accuracy of the distribution information, the user who received the notification can determine the accuracy of the distribution information and deal with it. When the traffic monitoring activity corresponding to the distribution information is not actually performed, there is a risk that the user's confidence in the distribution information will be greatly damaged, but if the above is also notified that the accuracy is low, the above It is possible to suppress the damage to the sense of trust.

In the notification terminal of one preferred aspect of the present invention, the relationship between the notification mode of the distribution information and the accuracy of the distribution information can be set by an operation on the user side.
While there are users who do not want to be notified of distribution information whose authenticity is uncertain, there are also users who want to make their own decisions after receiving notification of all distribution information regardless of whether it is true or false. If the distribution information to be notified can be selected according to the operation on the user side as described above, the distribution information can be appropriately notified to various users.

The notification terminal of one preferred aspect of the present invention can acquire vehicle information indicating the status of the attached vehicle, and changes the notification mode of the distribution information according to the acquired vehicle information.
The notification terminal of one preferred aspect of the present invention can acquire the speed as the vehicle information, and changes the notification mode of the distribution information regarding the speed control according to the acquired speed.
For example, when approaching the point of traffic monitoring activity of speed control, when the speed of the vehicle is high, the notification of the corresponding distribution information is output by voice, an alarm sound is generated, and the driver suppresses the speed. Is good to do. On the other hand, if the same notification is given when the speed is low due to traffic jams or the like, there is a risk that the driver who cannot achieve the speed at all may feel frustrated. In such a state, it is better to refrain from notifying the distribution information according to the approach.

The notification terminal of one preferred aspect of the present invention can notify the distribution information and can also notify the pre-stored traffic information regarding the traffic monitoring activity.
The notification of regulated traffic information is suitable for notification of traffic monitoring activities such as fixed speed control. On the other hand, the notification of the distribution information is suitable for notification of traffic monitoring activities that require real-time performance, such as mobile orbis, inspections, and patrols by police cars. By combining both, it is possible to provide detailed support for the safe driving of the driver who is the user.

The notification terminal of one preferred aspect of the present invention can acquire the current position and can notify information about the traffic monitoring activity carried out in the predetermined area based on the current position.
When notifying the information regarding the traffic monitoring activity, it is notified so that the user can distinguish whether the notification is based on the distribution information or the ready-made traffic information.
The distributed information is superior in real time to the regulated traffic information, but inferior in accuracy. When the distribution information is notified, if the distribution information is notified separately from the regulated traffic information, the user can determine the effective utilization of the distribution information in consideration of the above-mentioned characteristics.

A preferred aspect of the notification terminal of the present invention is integrated with a posting terminal of another aspect of the present invention.
In this case, it is convenient for the user because it is possible to post the posted information, browse the distribution information, and the like using one terminal.

As shown in FIGS. 1 and 2, the member management server 12 is a server device that manages members registered on the driving support system 1 side of this example. The member management server 12 includes a control board (control unit), a hard disk drive (HDD), and the like on which a CPU for executing arithmetic processing, ROM, RAM, etc., which are storage elements, are mounted, and a LAN port as an external interface. It is equipped with a communication port such as. The member management server 12 is connected to a public communication line via a communication port, and information communication with the posting server 11 is possible.

A user management database 121 for managing members is provided in the storage area of the hard disk drive accessible from the control unit. In the user management database 121, the member ID (My Jupiter ID) which is the identification information, the login password, the poster ID which is the identification information at the time of posting, the user personal information, and the information of the point where the member personally registered (My Jupiter point). ) Etc. are stored and managed for each member. The member management server 12 of this example having the user management database 121 has a function as an authentication means for authenticating the member ID inquired from the posting server 11.

(Posting server)
The posting server 11 is a server device that distributes posting target information that integrates posting information. The posting server 11 includes a control board (control unit), a hard disk drive (HDD), etc. on which a CPU for executing arithmetic processing, ROM, RAM, etc., which are storage elements, are mounted, and also has a LAN port or the like as an external interface. Equipped with a communication port. The posting server 11 is connected to a public communication line via a communication port, and can perform information communication with the posting server 11, the mobile terminal 2, and the like.

The storage area of the hard disk drive accessible from the control unit side includes a GPS target information database 111 that stores information related to traffic monitoring activities, and a user status database 113 that manages post evaluations for each member.
In the storage area of the GPS target information database 111, in addition to the prefabricated GPS area that stores the prefabricated traffic information that is the information of the traffic monitoring activity that has been confirmed by the system side, the post that temporarily stores the posted information for each traffic monitoring activity. An area, a distribution area for storing post target information to be distributed, a new arrival information area for storing past post target information for which distribution has been completed, and the like are provided. The posted target information in the new arrival information area is a candidate for the ready-made traffic information to be newly added to the ready-made GPS area. The GPS target information database 111 may be formed by using a single storage means such as a hard disk, or may be formed by using a plurality of storage means such as a hard disk or a flash ROM.

The ready-made traffic information of the ready-made GPS area is the location and area for information such as traffic monitoring facilities such as stationary Orbis, past traffic control activities such as seatbelt control and drinking inspection, and the frequency of accidents. It is driving support information (POI data) that combines the position information representing.
The posted information in the posting area is unprocessed information as posted from the mobile terminal 2. Details will be described later with reference to FIG. 17, but in this posting area, posted information for each traffic monitoring activity is managed in a list in the order of posting.
The posting target information in the distribution area is information during continuous distribution in which a plurality of posting information common to traffic monitoring activities are integrated.
The post target information in the new arrival information area is the past post target information whose distribution has ended. This post target information may be newly registered as ready-made traffic information after confirmation work by the administrator on the system side. For example, if the posted information about the unregistered N system (automatic number reading system) is stored as the ready-made traffic information, the staff on the system side visually confirms it on site and then newly registers it in the ready-made traffic information. Operation is possible. For example, when posted information and posted target information related to unregistered inspections are frequently recorded as ready-made traffic information, the administrator on the system side can consider registering as ready-made traffic information according to the frequency and the like.

As shown in FIG. 3, the post evaluations stored in the user status database 113 are the total number of posts, the number of correct posts (number of correct posts), the number of incorrect posts, the ratio of correct posts among all posts (correct post rate), and the overall evaluation. Each evaluation item of is included. The points of the comprehensive evaluation are the points given as shown in FIG. 4 according to the number of regular posts and the percentage of regular posts. In the user status database 113, the data of each evaluation item is managed for each contributor (member). For members whose postings are prohibited based on past posting results, the posting prohibition flag is set in the data area of the comprehensive evaluation. In this example, the point of comprehensive evaluation is treated as the accuracy of the posted information by the poster.

The posting server 11 of this example realizes the functions as the following means by causing the CPU to execute a server program which is a pre-installed computer program.
(1) Post receiving means A means for receiving posted information from a mobile terminal 2 or the like via a public communication line.
(2) Posting permission means A means for determining whether or not to permit acceptance of received posting information. The posting permission means refers to the user status database 113 (FIG. 2) by using the member ID included in the posting information, and determines whether or not to permit. Posting information by members with the posting prohibition flag will be refused, and other posting information will be permitted.

The wireless transmitter / receiver 241 of this example can transmit / receive digital audio data obtained by digitizing telephone audio by circuit switching, and also transmits / receives digital data such as posted information, posted target information, application programs, and map data by packet communication. It is possible.

The GPS receiver 242 is a receiver that receives GPS signals coming from GPS satellites and outputs the current time, position information (latitude / longitude) of the current position, current speed, altitude, and the like. The GPS receiver 242 is incorporated in the main body of the mobile terminal 2 so as to be located above the center on the back side in the vertical posture as shown in FIG. 7.

As shown in FIG. 8, the control unit 20 includes a CPU 201, a storage element ROM 202, a flash ROM 203, a RAM 204, an I / O unit 205 forming an input / output interface, and the like. The ROM 202 stores various control programs including the BIOS and the like. The flash ROM 203 stores various installed processing programs. The RAM 204 is a readable / writable storage element that is also used for the work area of the CPU 201 and temporary writing.

The control unit 20 causes the CPU 201 to execute a program read from the ROM 202 or the flash ROM 203, so that the CPU 201 has a telephone function, a data communication function, a map display function for displaying a map on the touch panel 21, and a posting information generation function for generating posting information. , A posting function for posting posted information, an alarm function for traffic monitoring activities, etc. will be realized. Each means for realizing these functions is formed in the control unit 20.

The posting information generation function and the posting function are incorporated by installing the dedicated posting software. This posting software can be downloaded from the application server 15 on the premise of membership registration on the driving support system 1 side (see FIG. 1). The posting software installed on the mobile terminal 2 incorporates encrypted data of a member ID and a login password given to registered members. In order to start the posting software on the mobile terminal 2, the member ID and password given at the time of registration are required to be entered, and the exact match between the information incorporated as encrypted data and the entered information is the starting condition of the posting software. It has become. In the driving support system 1 of this example, posting from an unspecified person other than the member is avoided in advance by requesting the input of the member ID or the like when the posting software is started.

In the storage area of the flash ROM 203, a map database in which map data is stored and a GPS target information database 111 in which GPS target information related to traffic monitoring activities are stored are provided. The GPS target information includes ready-made traffic information such as N system installation information, posting target information delivered from a posting server, and the like.
The map data (MAP data) can be downloaded from the server that provides the map (see FIG. 1). In this example, one of the application servers 15 of the posting software also serves as a map server.
The ready-made traffic information is stored in the GPS target information database 111 when the posting software is installed.
The posted target information is stored in the GPS target information when the distribution is received, and then deleted when a predetermined time elapses.

The storage area of the flash ROM 203 is further provided with a posting pin storage area for storing information related to the traffic monitoring activity to be posted. In the posting pin storage area, up to four posting pin information regarding the traffic monitoring activity to be posted can be stored. The post pin information is composed of the following information.
-Time information indicating the pin registration time (registration time of the position to be posted) where the posting pin is registered on the map-Position information (latitude / longitude, of the monitoring position (registered position of the posting pin) where the traffic monitoring activity is carried out) Address, control direction with the traveling direction of the own vehicle reversed 180 degrees)
・ Activity content information (including type information) indicating the type, implementation mode, method, etc. of traffic monitoring activities

The basic operation of the mobile terminal 2 of this example will be described.
On the home screen (not shown) of the mobile terminal 2 in which the posting software is installed, an icon of the posting software (not shown) is displayed. When the control unit 20 of the mobile terminal 2 captures a touch operation for this icon, the start splash screen 21A is displayed on the touch panel 21 and then the login screen 21B is displayed as shown in FIG. The login screen 21B is a screen for requesting input of the member ID and login password registered on the driving support system 1 side.

The control unit 20 verifies whether the member ID and login password entered via the login screen 21B exactly match the member ID and login password recorded in the posting software. When the member ID and the login password can be collated, the control unit 20 switches the display of the touch panel 21 to the home screen 21C. This home screen 21C is a screen on which a map of the area around the point of interest is displayed. At the bottom of the screen, in addition to the pin setting button 251 and the setting button 252, a WEB for guiding to a radar detector product site on the Internet. The guidance button 255 is arranged.

On the screen of the home screen 21C, the display area of the map is set so that the point of interest coincides with a predetermined position on the lower center of the screen. As the point of interest, the current position acquired by the GPS receiver is usually set. The control unit 20 sets the current position as the attention point and displays the surrounding map on the home screen 21C unless a user operation for changing the attention point is input. While the vehicle is running, the display area of the map is changed at any time so that the own vehicle mark 250 indicating the current position is located at a predetermined position on the lower center of the screen.
The setting button 252 of the "spanner" mark at the lower right of the home screen 21C is an operation button for displaying the various setting screens 21D of FIG. On the various setting screens 21D, it is possible to change settings such as a warning display mode, a mode of voice output, a setting of an alarm order, and a map display mode. The pin setting button 251 to the left of the setting button 252 is an operation button for registering a posting pin at a point of interest (usually the current position).
The home screen 21C is a basic screen displayed when the posting pin 262 is not registered. On the other hand, when one or more posting pins are registered, the standby / posting screen 21E (FIG. 11) of FIG. 11 to which the posting button 253 for starting posting is added becomes the basic screen.

When displaying the home screen 21C or the standby / posting screen 21E, the control unit 20 refers to the GPS target information database 111 and acquires the ready-made traffic information or the posting target information around the current position as shown in FIGS. 9 and 11. .. The control unit 20 scrolls and displays these information in the information display field 254, and displays the target icon 261 at the corresponding position on the map. In the information display field 254, character information for warning a traffic monitoring activity near the current position is displayed. Of the target icons 261 exemplified in FIG. 11, H in the circle indicates the new H system, N in the circle indicates the N system, and P in the circle indicates parking. The display of these ready-made traffic information or posting target information will be described in detail later.

Next, the operation of the driving support system of this example configured as described above will be described. Hereinafter, (1) the posting operation of the posted information by the mobile terminal 2 (posting terminal 101A in FIG. 1), (2) the generation and distribution operation of the posted target information by the posting server 11 that received the posted information, (3) the posting target. The alarm operation by the mobile terminal 2 (notification terminal 101B in FIG. 1) that has received the information distribution will be described in this order.

(1) Posting operation of posted information by the mobile terminal 2 The posting operation in a situation where the map around the current position is displayed on the home screen 21C or the standby / posting screen 21E while the vehicle is running will be described.
When a user of the posting software witnesses a traffic monitoring activity such as a mobile orbis, the current position can be registered by touching the pin setting button 251 (Fig. 11) on the home screen 21C or the standby / posting screen 21E. be. The control unit 20 that has detected the touch operation of the pin setting button 251 first acquires the time, the latitude / longitude of the current position, and the traveling direction from the GPS receiver 242 and temporarily stores them.

The control unit 20 confirms a vacant area in the post pin storage area, and stores new post pin information in the vacant area. At the time of registration of the post pin 262, the time information and the position information that form a part of the post pin information are stored based on the temporarily stored time, latitude / longitude, and traveling direction. The time information is the pin registration time temporarily stored. The position information is the latitude and longitude temporarily stored, the corresponding address, and the control direction obtained by reversing the temporarily stored traveling direction by 180 degrees. If there is no space in the post pin storage area, the earliest post pin 262 in time is deleted, and the corresponding post pin information stored in the post pin storage area is deleted to open the empty area. Secured. On the map displayed by the standby / posting screen 21E, the posting pin 262 is set at the position corresponding to the position information of the posting pin information. Up to four posting pins 262 can be set, and numbers are assigned in order from the earliest registration time. The post pin information in the post pin storage area is stored in a state in which the pin numbers of the corresponding post pins are associated with each other.

When the control unit 20 detects the touch operation of the post button 253, the control unit 20 displays the pin list screen 21F (FIG. 12) displaying the list of the post pin information stored in the post pin storage area on the touch panel 21. On the pin list screen 21F, in addition to the four pin selection buttons 256 for each posting pin, the return button 257 is arranged. On the right side of the pin selection button 256, the corresponding post pin information is displayed as text. This text display is a display of the posted pin information excluding the activity content information of the traffic monitoring activity, and includes the display of the latitude / longitude, the address, and the control direction in addition to the pin registration time. In this example, since the control direction is set as the required information of the posted information, in FIG. 12, in addition to the unregistered No. 4 pin button 256, the state in which the No. 3 pin button 256 whose direction is undetermined cannot be operated. It has become.

The orientation measurement by the GPS function of the mobile terminal 2 in this example is a radio wave broadcast from a plurality of broadcasting stations such as a GNSS space segment (artificial satellites such as GPS, SBAS, GLONASS, and COMPASS) or a mobile terminal base station. It is performed by measurement by the Doppler shift amount of the above or by a method relative to the past positioning point. It is confirmed when the vehicle speed reaches 10 km / h or more after the 1st Fix is completed (after the first positioning is possible). After that, although the measured directional value fluctuates according to the running, the directional measurement remains in the fixed state until the power is turned off. After the orientation measurement is confirmed, the pin setting button 251 on the standby / posting screen 21E can be operated even if the current position is not positioned, but the posting pin 262 is not set on the map because the current position cannot be acquired. Displayed during search (not shown). After that, the current position is acquired according to the return to the positioning state, and the posting pin 262 is set.

When the operable pin selection button 256 (No. 1 and No. 2 pin selection buttons 256 in FIG. 12) in the pin list screen 21F is touch-operated, the control unit 20 displays the posting screens 21G to K (posting screens 21G to K) on the touch panel 21. 13 to 16) are displayed as appropriate, and activity content information to be stored as post pin information is generated.
The posting screen 21G is a screen for selecting the type (category) of the traffic monitoring activity. The posting screens 21H and I are screens for selecting the embodiment and method of the traffic monitoring activity. The posting screen 21J is a confirmation screen for the generated posting information. The posting screen 21K is a display screen indicating that the posting is completed.
Here, the types of traffic monitoring activities are the types of traffic monitoring activities such as Orbis, N system, inspection, and enforcement. Variations in the modes and methods of traffic monitoring activities differ depending on the type of traffic monitoring activity. For example, in the case of an N system, there are no variations in embodiments or methods. On the other hand, there are variations of mousetrap and mobile orbis for crackdown, and there are variations of radar type, stealth type, etc. for mobile orbis. Whether or not the posting screens 21H and I are displayed in the posting operation differs depending on the type of traffic control activity and the like.

Of the posting screens 21G to K, the posting screens 21G, 21J, and 21K are screens that always pass through regardless of the type of the target traffic monitoring activity. On the other hand, the posting screens 21H and I are screens that do not go through depending on the type of traffic monitoring activity. For example, as shown in FIG. 14, when the type of traffic monitoring activity is N system (automatic number reading system), the posting screens 21H and I are not displayed because there is no variation in the embodiment or method. On the other hand, as shown in FIG. 15, when the type of traffic monitoring activity is control, the embodiment and method are subdivided, so it is necessary to display the posting screens 21H and I and have the user input information.

The control unit 20 generates activity content information corresponding to the operation button selected by the user operation in the process of passing through the posting screens 21G to I, and stores the activity content information in the posting pin storage area at any time. The activity content information that forms part of the posting pin information is confirmed when the posting screen 21J is reached. On the posting screen 21J, a posting button 259 and a return button 257 are arranged together with a text display of the generated posting information. When the touch operation of the post button 259 is detected, the control unit 20 reads the corresponding post pin information from the post pin storage area, and adds the member information of the poster such as the member ID and the registrant ID to the post information. To generate. The control unit 20 transmits the posted information generated in this way to the posting server 11, and when the transmission is completed, the display of the touch panel 21 is switched to the posting screen 21K. This posting screen 21K is displayed for a few seconds, and then is terminated in response to the return to the home screen 21C or the standby / posting screen 21E.

The posting screens 21H and I, excluding the posting screen 21G for selecting the embodiment and method of the traffic monitoring activity, are all provided with a selection button 258 "Other / Unknown". When the "Other / Unknown" selection button 258 is operated, the control unit 20 does not go through the sequence of the posting screen 21 illustrated in FIGS. 13 to 16, but the activity content stored in the posting pin storage area. The information is confirmed, and the posting screen 21J is immediately switched and displayed. In the mobile terminal 2 of this example with such specifications, for example, even a user who does not know the difference in the method of Orbis (speed violation) has a detailed level that "Orbis is installed" according to the knowledge level. Post information can be generated relatively easily. On the other hand, a user with a high level of knowledge who is familiar with the difference in the Orbis method can generate post information with a high level of detail by selecting either method on the posting screen 21I.

Further, as shown in FIG. 15, when the type is control, the posting screen 21I can be passed by selecting the "other / unknown" selection button 258 on the posting screen 21H. For users who do not have a very high level of knowledge, it may be troublesome for the posting screen 21 to be rolled out one after another, but the specification that a part of the posting screen 21 is passed as described above is not very familiar to the user. It is also effective in activating posting activities by.

The posted information posted by the operation of the mobile terminal 2 as described above includes the following information as in the text display of the posting screen 21J. Of these, the time information and location information are the information stored in the post pin storage area when the post pin 262 is registered, and the activity content information is stored in the post pin storage area in the process of passing through the post screens 21G to I. This is the stored information. Member information is added when posting to the post pin information read from the post pin storage area.
-Time information indicating the pin registration time-Location information of the monitoring position where traffic monitoring activities are carried out (latitude / longitude, address, direction)
・ Activity content information indicating the type, implementation mode, method, etc. of traffic monitoring activity ・ Member information of posters such as member ID and registrant ID

(2) Generation and distribution operation of posting target information by the posting server 11 When the posting information is received from the mobile terminal 2, the posting server 11 first requests authentication of the member management server 12. The member management server 12 requested to be authenticated refers to the user management database 121 (FIG. 2) using the member information received from the posting server 11 and determines the existence or nonexistence of the corresponding member. When the corresponding member is valid, the poster ID of the member is returned from the member management server 12.

When the posting server 11 is authenticated by the member management server 12, the posting server 11 refers to the user status database 113 and confirms the presence or absence of the posting prohibition flag for the poster. The posting server 11 deletes the posting information for which the posting prohibition flag is set without accepting it, and executes the acceptance processing for the posting information for which the posting prohibition flag is not set. In this reception process, first, the posted information is temporarily stored in association with the posted time (arrival time) of the posted information, and sorting for each traffic monitoring activity is executed. In this sorting, the condition of common type that the type of traffic monitoring activity is common, the condition of locational proximity that it is located within a radius of 100 m (predetermined range), and the predetermined time. Other posted information that satisfies all the conditions of temporal proximity that the posted information is posted within is searched from the posted area. When other posted information that satisfies all the conditions can be searched, the newly accepted posted information is classified as having the same traffic monitoring activity as the other posted information, and is sequentially accepted as shown in the posted information list in FIG. The posting numbers are assigned in order and stored in the posting area. On the other hand, if the past posting information satisfying the conditions of commonity of types, locational proximity, and temporal proximity is not stored in the posting area, the posting server 11 may use the posting server 11. A new post information list similar to that in FIG. 17 is newly generated starting from the newly accepted post information (post number 001).

When adding new post information to the post information list of FIG. 17, the posting server 11 refers to the user status database 113 using the poster ID of the new posting information, and inquires about the posting evaluation of the poster. As described above with reference to FIG. 3, the items of the post evaluation for each contributor include the total number of posts, the number of correct posts, the number of incorrect posts, the correct post rate, and the overall evaluation. When adding new posted information to the posted information list in the figure, the posting server 11 accumulates the points of the poster's comprehensive evaluation (FIG. 3), calculates and stores the accumulated points. As will be described in detail later, this cumulative point is used as an evaluation value of the accuracy of the posting target information based on the posting information. In this example, all the posted information is recorded as shown in FIG. 17, but instead, the posted information whose comprehensive evaluation point is below the reference point is not registered in the list of FIG. You may erase it.

The information detail level in the posted information list in FIG. 17 is a value indicating the degree of detail of the activity content information included in the posted information. In each of the posting screens 21H and I (FIGS. 13 to 16), the detail level of the posted information generated by making a significant selection other than the others is 3, and only one of the posting screens 21H and I is used. The post information generated by making a significant selection is the detail level 2, and the post information generated by making a significant selection only on the posting screen 21G is the detail level 1. As a matter of course, for the N system in which the posting screens 21H and I are not presented because there is no distinction between embodiments and methods, the information detail level of all posted information is level 1. On the other hand, there are various types, embodiments, and methods, and the information detail level such as mousetrap on which the posting screens 21H and I are presented varies depending on the posting information from detail level 1 to 3.

Here, the temporal proximity condition and the locational proximity condition, which are the conditions for sorting the newly received posted information, will be described.
The condition of temporal proximity is that the pin registration time of the new posted information is included within a predetermined time based on the pin registration time of the preceding posted information. As shown in FIG. 18, a different time is set for each posted information according to the comprehensive evaluation of the poster of the preceding posted information (FIG. 3) and the traffic volume of the monitoring position. Of the post evaluations, the higher the point of the overall evaluation, the longer the predetermined time is set. In addition, depending on whether the monitoring position is an urban area or a county area, whether it is an arterial road, the number of vehicles owned under the jurisdiction of the police station to which the monitoring position belongs, etc. It is set, and the longer the traffic volume, the longer the time is set.

As shown in FIG. 18, for example, after receiving the first posted information, when the second posted information satisfying the above two conditions of locational proximity and common type is received, the arrival time is set. Within a predetermined time set for the first posted information (the time indicated by the downward arrow in the figure), the second posted information is classified as having common traffic monitoring activities. Further, for example, with respect to the fifth post information satisfying the above two conditions after receiving the fourth post information, the arrival time is after the lapse of a predetermined time set in the fourth post information. , Within a predetermined time set in the third posted information. As a result, the fifth posted information is sorted as having the same traffic monitoring activity as the third posted information, like the fourth posted information.

The condition of locational proximity is that the position based on the newly posted information is included within a radius of 100 m centered on the reference point. The position of this reference point changes at any time as shown in FIG. 19 when the posted information is sequentially sorted. Here, B1, B2, B3 ... Represent each post information before the corresponding post target information is delivered, and A1, A2, A3 ... Each after the corresponding post target information is delivered. Represents posted information. The number following A or B indicates the order in which they were posted. For example, the posted information of B1 is the posted information that is the starting point of the first posting. A1 is the post information posted first after the corresponding post target information is delivered. The vertical direction in the figure shows the transition of time. The left-right direction indicates the position in the advancing / retreating direction on the road where the traffic monitoring activity to be posted is carried out. The right side indicates the backward side and the left side indicates the forward side with respect to the traveling direction of the vehicle.

When the posting server 11 receives the posting information B1 as the starting point, the posting server 11 first sets the corresponding monitoring position as the first reference point 1 (the point in the circle 1 in FIG. 19). After that, when the monitoring position is within a radius of 100 m centered on the reference point 1 and new posted information B2 relating to the traffic monitoring activity having a common type is received, the monitoring position of the posted information B2 and the reference point are received. The position between 1 and 1 is set as the new reference point 2. When the monitoring position is within a radius of 100 m centered on the reference point 2 (the point surrounded by the circle 2) and new posted information B3 related to traffic monitoring activities of the same type is received, the posted information B3 is monitored. The distance between the position (B3) and the reference point 2 is divided into three equal parts, and the position away from the reference point 2 on the monitoring position (B3) side is set as a new reference point 3 (point in the circle 3). Since the reference point 2 is a point based on two posted information, while the monitoring position (B3) is a point based on only one posted information, the position of this reference point 3 is based on the concept of weighted average. Determined in an intermediate position. Further, when the posting information B4 is grouped after the reference point 3 is set according to the reception of the posting information B3, the distance between the monitoring position (B4) of the posting information B4 and the reference point 2 is 4 A position separated from the reference point 3 on the monitoring position (B4) side by an equally divided distance is set as a new reference point 3.

The weighted average coefficient differs between before and after delivery of the post target information. Specifically, regarding the monitoring position of the posted information before distribution, the above-mentioned weighted average coefficient is set to 1, and for example, if the reference point is based on four posted information, a new monitoring position and a reference point are used. The distance is divided into 5 equal parts and shifted to the new monitoring position side. On the other hand, regarding the monitoring position of the posted information after distribution, the above weighted average coefficient is set to 2, and for example, if the reference point is based on 6 posted information, the distance between the new monitoring position and the reference point is set. It is shifted to the new monitoring position by twice the distance of eight equal parts.

In this way, the reason for different handling before and after delivery of post target information will be explained. Before distribution, it is necessary for any contributor to judge the type etc. in a short time until the traffic monitoring activity suddenly appears and passes. Therefore, the registration operation of the point of traffic monitoring activity tends to be after passing the point, and the point of the posting target actually registered shifts forward (passing direction) from the actual point. Probability is high. On the other hand, after distribution, it is known in advance that the type of traffic monitoring activity related to the posted target information is being performed, so the type of traffic monitoring activity actually being performed is as per the posted target information. The accuracy of determining whether or not there is a tendency tends to increase. Also, since you will be approaching that point while having a high interest in whether or not traffic monitoring activities are actually being carried out at the point related to the posted target information, the registered point will be exactly the actual point. easy. As described above, if the coefficient of the weighted average when determining the reference point before and after distribution is different and the coefficient of the monitoring position of the posted information after distribution is increased, the post after distribution is expected to have high accuracy of the monitoring position. Information can be quickly reflected in the position of the reference point, and the position accuracy can be improved.

The posting server 11 integrates the posting information and starts generating the posting target information for distribution for the traffic monitoring activity in which the cumulative points of the posting information list in FIG. 17 exceed a predetermined reference point. This post target information includes the following information.
-Time information indicating the earliest pin registration time of the posted information-Location information of the monitoring position where traffic monitoring activities are carried out (latitude / longitude, address, direction)
・ Activity content information indicating the type, implementation mode, and method of traffic monitoring activity ・ Accuracy information indicating the degree of certainty of the posted target information

In the position information of the post target information, the latitude and longitude of the average position of the latest 10 posted information, the address corresponding to the latitude and longitude, and the average direction of the average of the latest 10 posted information are set. .. It is also possible to set the reference point (FIG. 19) for determining the locational proximity to the latitude / longitude and the address in the position information included in the posted information.
In generating activity content information among the post target information, the post server 11 refers to the post evaluation (Fig. 3) for each contributor, has an overall evaluation score of 7 points or more, and has a correct post rate. Select information posted by 70% or more contributors. If the difference in the activity content information of the selected posted information is only the difference in the detail level, and there is no difference in the embodiment, method, etc., the activity content information of the posted information with the highest detail level is posted as it is. It is set in the activity content information to be included in the target information. On the other hand, if there is a difference in the embodiment, method, etc., the activity content information determined by majority vote is included in the posting target information. If it is not decided by a majority vote, the activity content information by the poster who is detailed and has a high positive posting rate among the selected posting information is given priority.
The latest cumulative points are set as they are for the accuracy information of the post target information.

The posting server 11 of this example stores all the posting target information generated as described above in the new arrival information area, and distributes posting target information other than the stationary Orbis and N system using a public communication line. do. The posting server 11 stores the posting target information about the stationary Orbis and the N system without distributing it, and then outputs it according to an output operation by the system administrator or the like. The posted target information, which is also the new installation information of the stationary Orbis and N system, is visually confirmed by the staff on the system side, and when it is visually confirmed, it is registered in the ready-made GPS area (GPS target information database 111 in FIG. 2). The ready-made traffic information registered in this way is distributed to users such as radar detectors that warn of the approach to GPS contents such as Orbis and N system, and is subsequently downloaded to the mobile terminal 2. Included in posting software.

(3) Alarm operation by the mobile terminal 2 Next, the alarm by the mobile terminal 2 will be described. The mobile terminal 2 of this example can execute an alarm using the prefabricated traffic information incorporated in the GPS target information database 111 at the time of installing the posting software and the posted target information stored in the GPS target information database 111 after receiving the distribution. Is. Such an alarm is executed during the display of the home screen 21C (FIG. 9) or the standby / posting screen 21E (FIG. 11). On the home screen 21C or the standby / posting screen 21E after receiving the posting target information, the target icon 261C of the ready-made traffic information is displayed as a circular mark, and the target icon 261R of the posting target information (delivery information) is a rectangle as shown in FIG. It is displayed as a mark.

The square target icon 261R of the post target information is displayed in different colors according to the accuracy represented by the accuracy information included in the post target information. Those with low accuracy are displayed in cool colors, and as the accuracy increases, they change to warm colors, and those with high accuracy are displayed in red. Instead of or in addition to this, the size of the square mark may be changed according to the accuracy of the posting target information.

When the control unit 20 of the mobile terminal 2 detects a touch operation on the rectangular target icon 261R, the control unit 20 displays a data display screen 21L for displaying detailed data of posted target information and the like, as shown in FIG. On this data display screen 21L, in addition to the detailed data of the posting target information, the accuracy, the number of postings, the occupancy ratio of the highly rated posters, the past results of similar traffic monitoring activities, and the posting list are displayed. When the control unit 20 detects a touch operation for any of the contributors in the contributor list, the control unit 20 switches and displays the content posted by the contributor and the display screen (not shown) of the points of the comprehensive evaluation of the contributor. .. The detailed information of the corresponding ready-made traffic information is also displayed at the time of touch operation with respect to the circular target icon 261C corresponding to the ready-made traffic information.

Further, the mobile terminal 2 displaying the home screen 21C or the standby / posting screen 21E has a monitoring position of the traffic monitoring activity of the ready-made traffic information or the posting target information according to the running of the vehicle, as shown in FIGS. 22 and 23. When approaching a GPS target), an alarm according to the type is executed. While the home screen 21C or the standby / posting screen 21E is being displayed, the control unit 20 refers to the GPS target information database 111 and acquires prefabricated traffic information or posting target information around the current position. The control unit 20 calculates the distance from the current location of the GPS target of the surrounding existing traffic information or the posted target information at any time, and detects the approach to the corresponding GPS target according to this distance.

FIG. 22 is an example of an alarm when approaching the installation position (monitoring position) of the N system and an alarm when approaching the seatbelt control area (monitoring area). The former is an example of a traffic monitoring activity warning that is carried out at a point rather than an area. The latter is an example of an alarm for traffic monitoring activities carried out in the area.
When the standby / posting screen 21E is displayed and the point of time and effort is reached to the installation position of the N system by 340 m, the control unit 20 displays a text display such as "N system 340 m" in the information display field 254 and the N system. Illustration 265 representing the above is displayed in a pop-up on the screen.
Upon reaching a point 340 m before the seatbelt control area, the control unit 20 displays a text display such as "seatbelt control 340 m" in the information display field 254 and displays the corresponding illustration 265 in a pop-up on the screen. .. Further, when the vehicle is traveling in the seatbelt control area, that is, when the current position belongs to the area, the control unit 20 displays a text display such as "seatbelt control" in the information display field 254. When the area is passed, that is, when the current position is out of the area, the character display in the information display field 254 is erased, and the original standby / posting screen 21E or the like is displayed.

FIG. 23 is an example of an alarm when approaching the installation position of the expressway Orbis. The timing of warning start when approaching the installation position of Orbis on the highway differs depending on whether the vehicle speed at that time exceeds the speed limit. When the speed limit is exceeded, the control unit 20 displays a text such as "Expressway Orbis 2000m" in the information display field 254 when it reaches the point of 2000m, as shown in the leftmost figure in the figure. And the corresponding illustration 265 is popped up. In addition, the control unit 20 executes a voice alarm such as "2 km ahead, XX road, loop coil Orbis."

On the other hand, when the speed is within the speed limit, the control unit 20 displays a text display such as "Expressway Orbis 1000m" in the information display field 254 when the point of 1000m is reached, as shown in the central figure in the figure. At the same time, the corresponding illustration 265 is displayed in a pop-up. In addition, a voice warning such as "1 km ahead, XX road, radar type Orbis" is executed. After that, when the point 500 m before is reached, a voice such as "The camera is on the right side" is output from the speaker 230.
Furthermore, when the vehicle reaches the point 300m immediately before, the information display field 254 that displays the text to that effect is displayed, and a voice warning such as "300m ahead, XX road radar type Orbis. The running speed is 120 km." Is issued. Execute.

It is also possible to add public control information to the posting target information delivered by the posting server 11. In this case, it becomes possible to notify and warn the public control information as shown in FIG. 24. The figure is an example of scrolling the text display "It is the seatbelt control week from August 1st" in the information display field 254.

As described above, by using the mobile terminal 2 of this example, it is possible to generate type information indicating the type of traffic monitoring activity carried out to promote traffic safety and post information including position information indicating the monitoring position. , Posting is possible to the posting server 11. The posting server-11 generates posting target information (delivery information) including type information and location information related to the traffic monitoring activity by integrating a plurality of posting information common to the traffic monitoring activities to be posted. The other mobile terminal 2 can execute notification, alarm, etc. using the posting target information from the posting server 11.

While the posted information from the mobile terminal 2 contains highly real-time information, the accuracy of the posted information varies, and there may be correct information or incorrect information. If a plurality of posted information whose authenticity is uncertain is distributed as it is in this way, there is a risk of confusion as to which information should be believed on the side of the mobile terminal 2 that has received the distribution.
On the other hand, according to the posting server 11 of this example, it is possible to deliver the posting target information with improved accuracy by integrating a plurality of posting information. This post target information is easy to use and useful information that has both real-time performance based on posted information and accuracy improved by information integration.

In particular, in this example, the posted information to be integrated is sorted by judging the three conditions of temporal proximity, common type of traffic monitoring activity, and locational proximity. According to such sorting, the posted information for a specific traffic monitoring activity can be accurately extracted. Furthermore, in integrating the posted information sorted in this way to generate the posted target information, the accuracy of the posted information is evaluated, and then the posted information with high accuracy is selectively used. Since the post target information is information generated by integrating the post information with high accuracy, the accuracy is high. Further, the posting target information generated by integrating the posted information that has undergone the accuracy evaluation is easy to evaluate the accuracy, and is easy to manage on the distribution side and the distribution receiving side. On the distribution side, it is also good to selectively distribute the posting target information according to the accuracy. On the side receiving the distribution of the posting target information, it is also possible to selectively perform notification or alarm according to the accuracy.

As described above, the driving system 1 of this example is a system for distributing posted target information based on posted information related to traffic monitoring activities such as traffic control and inspection to support driving, and is a system for supporting driving of the posted target information to be distributed. It is an excellent system that has both real-time performance and accuracy (reliability).

It may be configured so that the cancellation information indicating that the traffic monitoring activity related to the delivered post target information is not carried out can be generated as the post information. For example, a cancellation posting button for transmitting cancellation information may be additionally arranged on the data display screen 21L of FIG. 21 displayed by touching the square target icon 261R (FIG. 20) of the standby / posting screen 21E. good. On the posting server 11 side, it is preferable to authenticate the received cancellation information in the same manner as in the case of posting information. Posting after receiving the cancellation information When distributing the target information, it is also possible to include information such as the fact that the cancellation information has been accepted and the number of canceled posts. A cancellation post display field for displaying such information may be added to the data display screen 21L of FIG. Furthermore, the accuracy of the cancellation information is evaluated based on the number of posts of the same type of cancellation information and the occupancy ratio of highly rated posters, and when the accuracy exceeds a predetermined threshold, the distribution of the corresponding posting target information is stopped. It is also good to do.

It is also good to store the original posted information in the new arrival information storage area after the distribution of the posted target information is completed. These posted information are useful as reference information when considering whether or not to newly register the posted target information in the ready-made traffic information.
After the distribution of the posting target information is completed, it is preferable to execute the evaluation of the poster for each posting information in the posting information list in FIG. 17 and reflect the evaluation result in the content of the evaluation item. If you are a contributor who makes a correct post, the post evaluation will be higher and higher, while if you are a contributor who makes a wrong post, the post evaluation will be lower and higher, and there will be a difference in the post evaluation. If the difference in post evaluation becomes remarkable, when the post server 11 receives the post information, it becomes possible to easily determine the handling thereof, the integration of the integrated information becomes easy, and the accuracy of the post target information can be improved. ..
Instead of this example, while accepting posts from posters that cannot be specified on the system side, it is also possible to treat the posted information of an unspecified specific person as post information with low accuracy. In this case, the number of posts can be increased.

In this example, it is displayed in different colors according to the accuracy of the posting target information. In addition to this, the threshold value regarding the certainty of whether or not to display the post target information may be adjustable by the user's operation. In addition, it is also possible to configure the display mode of the posting target information with respect to the accuracy so that it can be set by the operation on the user side.

It is also possible to configure the mobile terminal 2 so that the position of the posting pin 262 on the map can be corrected by a user operation such as dragging after the posting pin 262 is registered and before the posting information is transmitted. In this case, the post information may include pin correction information indicating that the position correction operation of the post pin 262 has been performed. The posting server 11 may handle the posted information including the pin correction information by presuming that the position accuracy of the position information is higher than the post information not including the pin correction information, and reflect it in the position information of the post target information. good.

It is also possible to configure the mobile terminal 2 so that the position of the target icon 261R (FIG. 20) of the posting target information can be corrected by the user operation. Further, it is also possible to include the icon correction information indicating that the position correction operation of the target icon 261R has been performed in the posted information. On the posting server 11 side, it is preferable to handle the posted information including the icon correction information by presuming that the position accuracy is high and reflect it in the position information of the posting target information.
It is also good to equip the posting server 11 with a map database. If well-known map matching is performed using map data so that the monitoring position related to the posted information is located at a specific point, the position accuracy of the monitoring position can be ensured and the position accuracy of the posted target information can be improved. The specific points in map matching may be, for example, points on the road or points where crackdowns have been carried out in the past.

The mobile terminal 2 of this example displays a data display screen 21L that displays detailed data and the like of the posting target information as shown in FIG. 21 in response to a touch operation on the target icon 261R (FIG. 20) related to the posting target information. In this data display screen 21L, the contributors are displayed in a list in the order of the time of the posted information, but instead of this, the contributors with high points of overall evaluation may be ranked and displayed.

In this example, as shown in FIG. 4, the points of the overall evaluation of the posters are determined by the number of regular posts and the percentage of regular posts, and the accuracy of the posted information by each poster is evaluated by this. As an alternative method for evaluating the accuracy of posted information, a method based on evaluation from other users, a method of evaluating according to the degree of proximity of the distance to the past control position data collected in advance, and the like can be considered. For example, when the target icon 261R (for example, double tap) of the post target information is touch-operated (for example, double-tap), the integrated original post information monitoring position may be displayed. Further, if the evaluation screens of the corresponding contributors are switched and displayed by touching each monitoring position, each contributor can be evaluated relatively easily from the mobile terminal 2 side.

The freshness information is information indicating the implementation time of the traffic monitoring activity to be posted. As shown in FIG. 33 (c), data values representing freshness are defined according to the time when the target traffic monitoring activity is carried out. For example, in the case of posted information targeting traffic monitoring activities currently being carried out, the freshness value will be zero, and even posted information targeting traffic monitoring activities carried out within one month over one week. For example, the freshness value becomes 20. On the other hand, for the posted information for the permanent installation type Orbis etc., the data value of freshness is 255.
The direction type information is information that supplements the control direction included in the position information. By using the direction type information, it is possible to specify the control direction of the monitoring activity in the opposite lane, and also to specify whether the traffic monitoring activity is on the right side or the left side of the driving lane. For example, in the case of traffic monitoring activity targeting a traveling lane, 0x01, which is a 180-degree inversion of the traveling direction (traveling direction of a vehicle) of 0x02 in FIG. 34, is the type of control direction. For example, when the posting pin is registered in front of the Orbis installed in the median strip, the Orbis is set diagonally to the right of the driving lane. In this case, the type of control direction is 0x10 in the figure.

In the driving support system 1 of this example, (1) generation of posted target information using the radar detector 4, (2) transmission of posted information by the mobile terminal 2, (3) authentication of posted information by the member management server 12, Each operation and the like are different from the driving support system of the first embodiment. Hereinafter, the contents of each operation of (1) to (3) will be described.

(1) Generation of posted information When the control unit 40 of the radar detector 4 detects the operation of the memory button 522 while the map screen 62 of FIG. 29 is displayed, the control unit 40 includes four pin setting buttons 634 as shown in FIG. 35. The registration menu button 63 of is displayed in a pop-up on the screen. As the registration menu button 63, in addition to the pin setting button 634 for registering the posting pin 64 (FIG. 36), the ITY map button 631 for displaying the latitude and longitude of the vehicle positioning position when the button is pressed is displayed as a two-dimensional bar code. There is a My Area button 632 for registering My Area and a Cancel Button 633 for canceling the registered area.

When the pin setting button 634 is touch-operated, the control unit 40 sets the posting pin 64 at the current position of the map screen 62 as shown in FIG. 36, and at the same time, the position information (latitude / longitude, address, control direction) of the posting target. ) And the pin registration time are registered in the posting pin storage area. In the radar detector 4 of this example, which can register up to four post pin information in the post pin storage area, the post pin 64 can be registered up to four from the first pin to the fourth pin. In this figure, since all the pins were empty, the first pin was set to the current position as the posting pin 64, and the position information at that time, the pin registration date and time, etc. were stored in association with the first pin. This is an example. The activity content information indicating the type, embodiment, method, etc. of the traffic monitoring activity is generated according to the subsequent user operation (FIGS. 40 to 42) and stored in the posting pin storage area.

When all four post pins 64 are registered and four post pin information is stored in the post pin storage area, the registration menu button 63 of FIG. 37 is popped up in response to the operation of the memory button 522. To. Here, the registration menu button 634A including the display of "The pin is full" displays that the posting pin 64 (FIG. 36) cannot be registered.
In this example, since the control direction is essential information for the posting information, the posting pin 64 cannot be registered when the traveling direction by the GPS function is undecided as in the first embodiment. There is. When the memory button 522 is operated while the traveling direction is undetermined, the control unit 40 pops up the registration menu button 63 including the registration menu button 634B indicating the undetermined direction (FIG. 38). Further, when the memory button 522 is operated in the non-positioning state in which the positioning by the GPS function is not performed, the control unit 40 displays a telop on the upper part of the map screen 62 indicating that the GPS search is in progress (FIG. 39). ).

When the control unit 40 detects a touch operation on the map screen 62 (FIG. 29 or the like), the control unit 40 displays the setting screen 67A at the top of FIG. 40. On the setting screen 67A, various menu buttons including a posting button 670 for posting posting information are arranged. When the post button 670 is touch-operated, the control unit 40 switches to the display of the post pin menu screen 67B in the middle of the figure. The post pin menu screen 67B is a screen in which a confirmation button 671A and an erase button 671B are arranged for each post pin. For unregistered post pins, the operation buttons 671A and 671A and B are displayed in shadow and cannot be operated. The control unit 40 that has detected the touch operation to the pin confirmation button 671A reads the post pin information corresponding to the post pin from the post pin storage area. The control unit 40 displays texts of position information (latitude / longitude, address, control direction) and time information (pin registration date / time) among the read post pin information, as well as a post button 672 for starting the post process. The arranged pin confirmation screen 67C is displayed. The generation of post information is started in response to the touch operation of the post button 672.

When the control unit 40 detects the touch operation of the posting button 672 in the pin confirmation screen 67C as shown in FIG. 41, the control unit 40 appropriately displays the posting screens 67D to 67I of FIGS. 41 and 42 according to the type of traffic monitoring activity and the like. , Displayed on the touch panel 45. The posting screens 67D to 67F of FIG. 41 are screens for generating activity content information (FIG. 32) such as the type (category) of the traffic monitoring activity to be posted, its embodiment, and the method. The posting screens 67D to F correspond to the posting screens 21G to I (FIGS. 13 to 16) of the first embodiment, respectively. The control unit 40 adds the activity content information generated in response to the user operation on the posting screens 67D to 67F to the posting pin information stored in the posting pin storage area. Except for the posting screen 67D for selecting the type of traffic monitoring activity to be posted, the posting screens 67E and F for selecting the embodiment and method are set with operation buttons for selecting other or unknown. The purpose of providing an operation button for selecting other etc. on the posting screens 67E and F is to facilitate posting by a user who is not very familiar with traffic control and to activate posting.

The posting screen 67G of FIG. 42 is an operation screen for inputting freshness information (FIG. 32) indicating the implementation time of the traffic monitoring activity to be posted. On this posting screen 67G, in addition to the operation button for selecting the current implementation, the operation button within one week, the operation button within one month, the operation button within three months, and the like are arranged. The driving support system 1 of the first embodiment is a system that is supposed to be posted for the traffic monitoring activity currently being carried out, while the system of this example is also capable of posting for the past traffic monitoring activity. It has become. The control unit 40 adds the freshness information corresponding to the operation button selected on the posting screen 67G to the posting pin information stored in the posting pin storage area.
The posting screen 67H is a posting screen for selecting the type of control direction. On this posting screen 67H, "driving lane", "opposite lane", "right direction", "left direction", "driving lane right side", "driving lane left side", "opposite lane left side", "opposite" The operation buttons for "on the right side of the lane" are arranged. The control unit 40 adds the direction type information (FIGS. 32 to 34) corresponding to the operation button selected on the posting screen 67H to the posting pin information stored in the posting pin storage area.

When any of the operation buttons is operated on the posting screen 67H as described above, the generation of the posting pin information (FIG. 32) is completed. The control unit 40 reads the post pin information from the post pin storage area, adds the product information (FIG. 32), and generates the post information. Then, a code image 670 in which this posting information is recorded is generated, and as shown in FIG. 42, the posting screen 67I including this code image 670 is displayed on the touch panel 45.
The posting user may take the code image 670 with the mobile terminal 2 that has started the posting software corresponding to the code image. In the mobile terminal 2 that has captured the code image 670, image processing is executed, the code image 670 in the captured image is cut out, and the posted information recorded in the code image 670 is read. The control unit of the mobile terminal 2 immediately transmits the posted information read in this way to the posting server 11.

When the posting server 11 receives the posting information, it first requests the authentication of the member management server 12. The member management server 12 requested to be authenticated refers to the user management database 121 using the product information (serial number, etc.) received from the posting server 11 and determines the existence or nonexistence of the corresponding purchaser. When the corresponding purchaser is validly present, the poster ID of the purchaser is returned from the member management server 12. When the posting server 11 is authenticated by the member management server 12, the posting server 11 refers to the user status database 113 and confirms the presence or absence of the posting prohibition flag for the poster. The posting server 11 deletes the posting information for which the posting prohibition flag is set without accepting it, and executes the acceptance processing for the posting information for which the posting prohibition flag is not set.

The reception process of this example is different from the posted information in which the data value of the freshness information (FIG. 33) is zero and the posted information other than that. The freshness information is zero, that is, the real-time posted information for the traffic monitoring activity currently being carried out is handled in the same manner as in the first embodiment and becomes the source information of the posted target information for distribution.
On the other hand, other posted information, that is, posted information related to permanent traffic monitoring activities such as N system (data value of freshness information is 255), and posted information related to past traffic monitoring activities are described in Example 1 of the posting server 11. It is stored in the same new information area and becomes the original information of the newly registered ready-made traffic information.
The other configurations and effects are the same as in Example 1.

The posting screens 67E to H (FIGS. 41 and 42) may be provided with a "immediate posting button" for jumping to the posting screen 67I. If any of the Orbis button, N system button, control button, and inspection button is selected by the posting screen 67D corresponding to the posting screen 21G (FIGS. 13 to 16) of the first embodiment, the type of traffic monitoring activity is confirmed. .. After the type of traffic monitoring activity is confirmed in this way, even if the posting buttons on the posting screens 67E to H are operated immediately after that, it is possible to generate posting information including the type information indicating the confirmed type. ..

The registered post pin 64 (FIG. 36, etc.) can be deleted by operating the delete button 671B on the post pin menu screen 67B in the middle of FIG. 40. When the erase button 671B is operated, the erase of the corresponding post pin is completed via the screen for confirming the erase and the screen for displaying that the erase is completed, as shown in FIG. 43 (a). By operating the system button arranged in the lower right corner of the setting screen 67A at the top of FIG. 40, the data erasure screen can be switched and displayed as shown in FIG. 43 (b). If you select the post pin button on this data deletion screen, you can delete the post pin and the corresponding post pin information all at once.

The posted target information distributed by the driving support system 1 of this example is information about the traffic monitoring activity currently being carried out as in the first embodiment. Alternatively or additionally, it is also possible to deliver post target information generated by integrating post information about past traffic monitoring activities with freshness information (FIG. 33) other than 255 or zero. In this case, for example, one or more posted information for traffic monitoring activities carried out two months ago, posted information for the same type of traffic monitoring activity one month ago, and the same type within one week. By integrating the posted information for traffic monitoring activities, it is possible to generate posted target information for points requiring attention where traffic monitoring activities are frequently carried out.
Here, in order for the above-mentioned one or more posted information to be sorted as the posted information for the common traffic monitoring activity two months ago, the temporal proximity and the locational proximity regarding the implementation time are required. And it is necessary to satisfy the three conditions of commonality of types. In addition, in order for the posted information for a specific traffic monitoring activity two months ago to be sorted as for a common traffic monitoring activity one month ago for the traffic monitoring activity that was carried out in the same way, it is a place. It is necessary to satisfy the two conditions of proximity and commonality of types.

In this example, the posted information is transferred to the mobile terminal 2 by using the code image 670 (FIG. 42) displayed by the radar detector 4. Instead of this, the radar detector 4 and the mobile terminal 2 may be connected in a communicable state by wireless communication such as WiFi, and the posted information may be transferred (see FIG. 1). For example, if the posting button displayed on the touch panel 45 of the radar detector 4 is operated while the dedicated software is running on the mobile terminal 2, the posting information is posted via the mobile terminal 2. It is also good to configure it as follows. In order to equip the radar detector 4 with a WiFi function, a WiFi module or the like may be incorporated. The mobile terminal 2 may be any mobile terminal having an access point (tethering) function.

If the radar detector 4 is capable of wireless communication with the mobile terminal 2, it is also possible to receive the distribution of the posting target information via the mobile terminal 2. The radar detector 4 can notify and warn the posted target information. Further, if the public control information is distributed, the radar detector 4 can notify the public control information as shown in FIG. 44. The radar detector 4 illustrated in the figure scrolls and displays the distributed public control information at the bottom of the map screen 62.

It should be noted that the driving support system may be compatible with both the posted information of Example 1 and the posted information of this example. The posted information of the first embodiment and the posted information of this example may be integrated to generate the posted target information. In this case, the accuracy evaluation may be different between the posted information generated by the mobile terminal 2 and the posted information generated by the radar detector 4. For example, as for the poster who has purchased the radar detector 4 and is actually using it, it is possible to assume a person who attaches great importance to the warning function and the like and has abundant knowledge about traffic control. There is a high possibility that the accuracy of information posted by such contributors can be highly evaluated.

In this example, the cumulative points (FIG. 17) of the posted information list are used as the accuracy of the posted target information. In addition to this, the accuracy may be evaluated based on the implementation history of past traffic monitoring activities. For example, if there is a history of similar traffic monitoring activities in the past, set an accuracy of 120% of the accumulated points (value increased by 20%), or add history points to the accumulated points. It is also good to do it. As a history point, a point that reflects the frequency of implementation is good. In determining the implementation history of past traffic monitoring activities, it is also good to use the posted target information in the new information area in addition to the existing traffic information.

It is also possible to change the notification or warning mode of the posted target information according to the vehicle information acquired by the OBD function such as the speed of the vehicle. For example, when the speed exceeds the speed limit, the posting target information regarding the mobile orbis etc. becomes very important.

(Example 3)
This example is an example in which the posted information is delivered as it is based on the driving support system of the first embodiment. This content will be described with reference to FIGS. 17 and 45 to 47.

As the posted information to be distributed, for example, the posted information whose posting evaluation point of the poster is 8 points or more and is not yet reflected in the posting target information, and the fluctuation of the monitoring position such as the police car under guard. Along with this, there is posted information where real-time performance is important.
FIG. 45 is a display example of posted information regarding police motorcycles. In this figure, the information pin 271 is displayed at the monitoring position corresponding to the posted information of the police motorcycle on the map displayed on the touch panel 21 of the mobile terminal 2. In the figure, the balloon display 275 displayed when the information pin 271 is tapped (touch operation) is also shown. The balloon display 275 displays the posting date and time, the activity content of the traffic monitoring activity related to the posting information, and the like. For posted information where real-time performance is important, set a limit such as 6 hours for the displayed time, manage this time limit on the mobile terminal 2 side, and delete the information pin 271 according to the passage of the time limit. It is also good to do. The illustration of the information pin 271 may be changed depending on the type of the target traffic monitoring activity, and the display color and size of the information pin 271 may be changed depending on the degree of risk.

Further, in the figure, a scroll display field 278 is provided at the bottom of the display screen of the touch panel 21. The scroll display field 278 is a display field for post information that does not include a monitoring position in the map area displayed on the touch panel 21 among the post information delivered as described above. If such a display is provided, posted information having a monitoring position in a distant place that is not included in the map area can be displayed. As a distant range, a range such as 20 km can be set. It is also possible to selectively display distant posted information located in the traveling direction of the vehicle, distant posted information located on the traveling road, and the like. It is also possible to display the public control information in FIG. 24 referred to in Example 1 in the scroll display column 278, but in this case, the background color is changed between the public control information and the posted information, and so on. It is advisable to devise ways to make it easier to distinguish between public control information.

As the message structure for scrolling the posted information, for example, the structure shown in FIG. 46 can be adopted. In the case of such a message structure, for example, "Yuppi-san (35) 10:30 on June 6 [Speed control (radar)] In front of Yupiteru, Iwazu-cho, Okazaki-shi, Aichi I'm doing it as usual. Be careful! You can scroll the message such as ". As for the posting experience value, a value that increases in proportion to the number of postings is good. For example, the number of positive posts and the overall evaluation shown in FIG. 3 may be adopted as the posting experience value. In addition, in order to increase the number of users such as posting enthusiasts who like posting, it is also effective to give a prize by commending the top 3 posting experience points of the year. At the end of the year, the posting server may be equipped with a program that selects the top three posting experience points of the year. Such an event provides an incentive for posting and contributes to more accurate collection of posted information.

Post information may be delivered automatically from the posting server (for example, every 10 minutes). As shown in FIG. 45, the update button 272 may be provided so that the distribution is immediately executed in response to the operation of the update button 272. Further, the posted information may be selectively distributed only to the desired users. This is because there are some users who do not want to deliver the posted information that is not accurate enough.

In order to distribute the posted information, it is also good to use the distribution file for each of 47 prefectures. By using such a distribution file, for example, posted information in Aichi prefecture can be collectively distributed to users traveling in Aichi prefecture. At the time of distribution of the distribution file for each prefecture, in addition to the distribution file of the prefecture to which the current position belongs, the distribution file of the adjacent prefecture may be distributed at the same time. Further, the posted information to be included in the distribution file may be limited to the posted information within 6 hours from the posting time (the time received by the posting server). The posted information for one case may be, for example, the following contents.
・ Latitude and longitude example, 34.794025 degrees, 137.117188 degrees ・ Display period example, June 6, 2012 10:25 to June 6, 2012 16:25 ・ Control content example, speed control (white police motorcycle)
・ Address information Examples of prefectures, examples of cities, wards, towns and villages in Aichi prefecture, examples of street names in Nishio city, 2 in XX town ・ Detailed locations and nearby landmarks (data may not be available)
For example, the road / comment from the intersection between JA of Nishihatazu and Sugi Pharmacy toward Kota (there may be no data).
For example, this is a place I often do. Be careful of the speed limit of 40km.
-User information User name example, Yuppi posting experience value example, 121

In the mobile terminal 2 of this example, the generation of posting information can be started by the touch operation of the posting button 273 in FIG. 45. When the post button 273 is touch-operated, a post page (not shown) is displayed. On this posting page, the latitude / longitude when the posting button 273 is touch-operated, the date / time, the date / time, and the text display of the address information, as well as the operation means such as a rotating drum for selecting the type of traffic monitoring activity, etc. It is also good to provide a picker view. For detailed locations and comments, it is good to let them enter text. In addition, in order to deal with posters who have trouble entering text, it may be possible to pass the input for detailed locations and comments. If the comment etc. is passed, it is also good to configure it so that a nice comment is added on the posting server side.
The other configurations and effects are the same as in Example 1.

In this example, information posted far away outside the map area is scrolled to the bottom of the screen. Instead, as shown in FIG. 47, the posted information whose monitoring position is located on the right side of the map area is scrolled to the strip-shaped space 278R at the right end of the screen, and the monitoring position is located on the upper side. The posted information may be scrolled and displayed in the space 278U at the top of the screen. In this case, the direction of the distant posted information can be grasped according to the scrolled position.
