  By using the posting terminal according to the present invention, it is possible to generate post information including type information indicating the type of traffic monitoring activity performed to promote traffic safety, and position information indicating the monitoring position, and to the server device Can be posted. The server device generates distribution information including type information and position information related to the traffic monitoring activity by integrating a plurality of pieces of posted information with common traffic monitoring activities to be posted. The notification terminal can notify the distribution information distributed from the server device.

  The distribution information can be, for example, highly real-time information generated based on the posted information, but the accuracy of the posted information varies, and there may be correct information or incorrect information. If a plurality of pieces of post information that are not true or false are distributed as they are, there is a risk of confusion as to what information should be believed on the notification terminal side. In particular, when a notification terminal is installed in the vehicle or when a portable notification terminal is brought into the vehicle, for example, if such posted information is distributed as it is while the driver is driving, it may hinder driving. There is a risk.

  On the other hand, for example, the distribution information in the present invention may be information whose accuracy is improved by integrating a plurality of pieces of post information. In this distribution information, for example, real-time properties based on posted information and accuracy improved by information integration are compatible. Distribution information in which real-time performance and accuracy are compatible 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 useful for realizing a driving support system with improved real-time performance. .

The traffic monitoring activities that are the subject of posted information in the present invention include traffic control such as speed control, parking prohibition control, seat belt control, etc., alcohol drinking check and seat belt check.
The server device in the present invention may have both a function of receiving the posted information and a function of transmitting the delivery information, or a server that receives the posted information and the delivery information. The server to be connected may be connected by a dedicated line, a dedicated communication line, a public communication line, or the like.

  The server device in the driving support system according to a preferred aspect of the present invention uses a plurality of pieces of posted information whose time related to posting of the posted information is within a predetermined time and whose monitoring position belongs within a predetermined range. Handle as post information for traffic monitoring activities.

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

The position information indicating the monitoring position in the driving system according to a 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. is there.
A road where a vehicle can travel in both directions opposite to each other except for a one-way road is generally used. Some traffic monitoring activities performed on the road target only one of the traveling directions, such as road speed control and inspection. If the distribution information can identify the traveling direction targeted by the traffic monitoring activity, it becomes more useful to the driver driving the road on which the traffic monitoring activity is performed. Because the degree of importance of the distribution 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. is there.

The server device in the driving support system according to a preferred aspect of the present invention evaluates the accuracy, which is the degree of likelihood of the posted information, and integrates a plurality of posted information to generate the distribution information according to the accuracy. Change the handling of each post information.
There are the following examples of handling post information according to accuracy. For example, the distribution information is generated using only posting information with a certain accuracy or higher. For example, post information that does not satisfy a certain degree of accuracy is handled as one piece of post information when a plurality of similar post information is posted. For example, the number of posts of the same type within a radius of 100 m is one.

The server device in the driving support system according to a 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 specified and the posting performance of the posted user. To do.
In general, it is possible to estimate that post information from a specific person is more accurate than post information from an unspecified person. For a specific contributor, it is also possible to make a point such as the number of times of posting correct post information, and use that point when evaluating the accuracy of the post information by the specific contributor.

As a posting terminal in the driving line-of-sight system of a preferred aspect of the present invention, various application programs including a dedicated machine in which the posting function for posting information is incorporated in advance and an application program for incorporating the posting function for posting information There is a general-purpose machine that can be selected and installed by the user,
The server apparatus evaluates the accuracy of the posted information depending on whether the posted information is information posted from a dedicated machine or whether the posted information is posted from a general-purpose machine.

  The introduction cost on the user side for using the posting function and the expectation for the distribution information differ between the dedicated machine and the general-purpose machine. For example, when the application program of the general-purpose machine is free software or the like, there is a possibility that a user who is not interested in the distribution information will post with mischief. On the other hand, considering that a dedicated machine is purchased, it can be estimated that a contributor from the dedicated machine has a sense of expectation in the distribution information. For this reason, for example, when the details of the posted information itself and the quality of information are substantially 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 according to a preferred aspect of the present invention evaluates the accuracy of the posted information with reference to information relating to the implementation status of past traffic monitoring activities.
For example, if post information related to speed control is posted at a point where speed control by a mobile orbit is frequently performed, the accuracy of the post information can be highly evaluated. On the other hand, if post information related to speed control is posted at a point where speed control by mobile orbis has never been carried out, first, the accuracy of the post information is evaluated low, while similar post information It is also possible to review the evaluation of the accuracy of the first posting information when is posted twice.
The information related to the implementation status of the past traffic monitoring activity may be, for example, an implementation history of the past traffic monitoring activity, or existing traffic information stored in advance regarding the traffic monitoring activity. In particular, the existing traffic information that has already been accumulated by the in-vehicle device such as the radar detector without depending on the posted information may be used as information regarding the implementation status of past traffic monitoring activities. Furthermore, information obtained by adding past posted information to the already-stored existing traffic information may be referred to as “information regarding the implementation status of past traffic monitoring activities”.

In the server apparatus in the driving system according to a preferred aspect of the present invention, the post information is handled depending on whether the post of the post information is received before or after the distribution information relating to the corresponding traffic monitoring activity is distributed. Are different.
Before distribution, for any contributor, the traffic monitoring activity to be posted appears unexpectedly, and it is necessary to determine the type or the like in a short time before passing. There is a tendency that the registration operation or the like of the point of the traffic monitoring activity is performed after passing the point, and the actually registered point may be shifted forward in the traveling direction from the actual point. On the other hand, if it is after distribution, it is known in advance that the type of traffic monitoring activity related to the distribution information is performed, so whether the type of traffic monitoring activity actually performed is as the distribution information There is a tendency that the accuracy of the determination of whether or not is high. In addition, while being highly interested in whether traffic monitoring activities are actually performed at the point related to the distribution information, it will approach that point, so the registered point will be easy to match the actual point . Or, if it is a quick contributor, there is a possibility that it is shifted to the near side from the actual point. If the post information after distribution of the distribution information is handled in consideration of such circumstances, the accuracy of the distribution information can be improved including the position accuracy.

The server device in the driving support system according to a preferred aspect of the present invention determines whether or not to distribute the distribution information and a distribution time for continuing the distribution according to the type of traffic monitoring activity.
For example, traffic monitoring activities such as speed control, such as mobile orvis, are generally known in duration and do not last for 24 hours. Based on such knowledge, it is preferable to determine the distribution time of distribution information.
On the other hand, with regard to information on fixed speed control, N system, and the like, there is a tendency for accuracy closer to 100% than real-time performance. Therefore, for post information targeted for fixed speed control and N system etc., rather than delivering delivery information immediately upon receipt, the system operator staff visits the site and visually confirms, It may be provided to the user as confirmed information.

The posting terminal in the driving support system according to a preferred aspect of the present invention can post cancellation information indicating that the traffic monitoring activity corresponding to the distribution information is not implemented,
The server apparatus evaluates the accuracy of the posted cancellation information, and determines whether or not to end the distribution of the corresponding distribution information according to the accuracy.
If posting of the cancellation information is accepted, distribution can be completed as soon as possible after the corresponding traffic monitoring activity is completed. Although the target traffic monitoring activity is not performed, the situation where the corresponding distribution information continues to be distributed can be suppressed as quickly as possible. Furthermore, the cancellation information is useful for canceling delivery of erroneous delivery information based on fake posting information at an early stage, or for giving a negative evaluation to a poster of fake posting information.

When the server device in the driving support system according to a preferred aspect of the present invention distributes the distribution information related to the corresponding traffic monitoring activity after receiving the cancellation information post, the cancellation information has been posted. Is included in the distribution information.
On the user side, when determining the accuracy of the distribution information, the user can make a determination in consideration of whether or not the cancellation information is posted. The lack of corresponding traffic monitoring activities is the biggest factor that impairs the user's confidence in the distribution information. When delivering the distribution information, it is also possible to notify the user that the cancellation information has been posted. Even if the corresponding traffic monitoring activity is not implemented, the loss of the user's trust in the distribution information is minimized. It can be suppressed close to. The information indicating that the cancellation information has been posted may be, for example, information indicating whether or not there is cancellation information posting in the integrated posting information. In particular, it may be information indicating the number of cancellation information posted. For example, the number of posts with integrated post information and the number of posts with cancellation information out of the number of posts may be distributed.

A posting terminal according to a preferred aspect of the present invention includes means for generating posting information in which the degree of detail of the type information differs according to a knowledge level related to a traffic monitoring activity on the user side.
For example, when the target traffic monitoring activity is speed control, the type includes mouse catch, mobile orvis, tracking, and the like. Further, for example, in the case of mobile orvis, there are types such as a radar type, a stealth type, and a phototube type. Detailed information can be posted by users who are deeply interested in traffic monitoring activities such as speed control, and who can recognize the type by simply looking at the equipment and devices. On the other hand, users who can recognize traffic monitoring activities related to speed violations, but who have limited knowledge of speed measurement, requesting detailed information when posting may make posting difficult and make the posting frustrating. high. Therefore, users who have knowledge about traffic monitoring activities can generate detailed posting information, while those who are not so can simply post posting information with a detailed degree of speed control. Can be promoted. If the posted information as an information source increases, the real-time property and accuracy of the distribution information can be improved.

The posting terminal according to a preferred aspect of the present invention is capable of acquiring a current position, and combining the position information based on the acquired current position with the type information generated by an operation on the user side. Is generated.
In this case, the accuracy of the position information included in the posted information can be improved. As a configuration capable of acquiring the current position, there are, for example, a configuration having a positioning function by GPS, a configuration of acquiring information on the current position from an external terminal having a GPS function, and the like.

A posting terminal according to a preferred aspect of the present invention is a first terminal capable of generating the posting information in response to an operation on the user side, obtains posting information from the first terminal, and proceeds toward the server device. It is comprised by the combination with the 2nd terminal which transmits.
The first terminal is a terminal capable of acquiring a current position and displaying a code image in which the post information is recorded,
The second terminal may be a terminal that can capture a code image displayed by the first terminal and read the recorded posting information.
As the second terminal, a mobile terminal such as a smartphone (multifunctional mobile terminal) having a camera function 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 a code image in which the post information is recorded. Such a first terminal can be sufficiently realized not only by a display screen of about 3 to 4 inches but also by a hardware configuration provided in an existing radar detector having a GPS function.

A posting terminal according to a 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 posting information is generated by associating the type of the traffic monitoring activity selected by the user's operation with the position information representing the specific point registered in advance.
If it is on the displayed map, the specific point can be registered with high positional accuracy. Post information generated through registration of such a specific point is highly accurate information with high positional accuracy.

The posting terminal according to a 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 easily located. You can register with high accuracy.

The notification terminal according to a 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, appropriate distribution information according to the driving situation can be notified. For example, even if the distribution information of the traffic monitoring activity at a point that is far away from the current position of the user and is not sure whether or not to go is reported, the information becomes low value for the user. On the other hand, distribution information related to traffic monitoring activities performed in the vicinity of the user's current position is information that is highly valuable to the user, and thus should be notified. Furthermore, a navigation function is provided, and traffic monitoring activities at points on the route calculated by the route calculation function may be notified early when the distance is long.

The distribution information acquired by the notification terminal according to a preferred aspect 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 in accordance with the accuracy of the distribution information, the user receiving the notification can determine the accuracy of the distribution information and deal with it. If the traffic monitoring activity corresponding to the distribution information is not actually performed, the user's confidence in the distribution information may be greatly damaged, but if the fact that the accuracy is low is also reported The damage of reliability can be suppressed.

In a notification terminal according to a 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 a user operation.
While there are users who do not want to receive notification of distribution information that is not true or false, there are also users who want to make their own judgment after receiving notification of all distribution information regardless of authenticity. As described above, if the distribution information to be notified according to the operation on the user side can be selected, the distribution information can be appropriately notified to various users.

A notification terminal according to a preferred aspect of the present invention can acquire vehicle information representing a situation of an attached vehicle, and changes a notification mode of distribution information according to the acquired vehicle information.
The notification terminal according to a preferred aspect of the present invention can acquire the speed as the vehicle information, and changes the notification mode for the distribution information related to speed control according to the acquired speed.
For example, when approaching a speed control traffic monitoring point or when the speed of the vehicle is high, a notification that the driver suppresses the speed, such as outputting a notification of the corresponding distribution information or generating an alarm sound, etc. Good to do. On the other hand, if the same notification is given when there is a traffic jam or the like and the speed is low, there is a risk that the driver's frustration feeling that the speed cannot be achieved at all will be aggravated. In such a state, it is preferable to refrain from notifying the distribution information according to the approach.

A notification terminal according to a preferred aspect of the present invention is capable of notifying the distribution information and notifying pre-stored traffic information stored in advance regarding traffic monitoring activities.
The notification of the 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 properties, such as mobile orvis, inspection, and patrol by a police car. By combining the two, it is possible to provide detailed support for the safe driving of the user driver.

A notification terminal according to a preferred aspect of the present invention is capable of acquiring the current position, and capable of notifying information on traffic monitoring activities performed in a predetermined area based on the current position,
In 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 notification based on the established traffic information.
The distribution information is superior in real time to the regulated traffic information, but inferior in accuracy. When the distribution information is notified, if the notification is performed separately from the regulated traffic information, the user can determine effective use in consideration of the above characteristics of the distribution information.

A notification terminal according to a preferred aspect of the present invention is integrated with a posting terminal according to another aspect of the present invention.
In this case, posting of posted information and browsing of distribution information can be performed using a single terminal, which is convenient for the user.

The code | symbol 101A of FIG. 1 has shown the structure as a posting terminal of this example, and the code | symbol 101B has shown the structure of the alerting | reporting terminal of this example. Reference numerals 102A and 102B indicate the configuration of a posting terminal or a notification terminal described in the second embodiment. Instead of this example, the posting server 11 and the member management server 12 may be integrated, or may be connected via a dedicated line so that communication is possible. The posting server 11 and the member management server 12 may be installed in the same place or in different places.

(Member management server)
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. This member management server 12 includes a control board (control unit), a hard disk drive (HDD), etc. on which a CPU that executes arithmetic processing, ROM and RAM as storage elements are mounted, and a LAN port as an external interface. Etc. are provided. 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, a member ID (My Jupiter ID), which is identification information, a login password, a contributor ID serving as identification information at the time of posting, user personal information, and information of a point personally registered by a member (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.

(Post 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), and the like on which a CPU for executing arithmetic processing, ROM, RAM, and the like as storage elements are mounted, and a LAN port as an external interface. It has a communication port. The posting server 11 is connected to a public communication line via a communication port, and information communication with the posting server 11, the portable terminal 2, and the like is possible.

The storage area of the hard disk drive that can be accessed from the control unit side includes a GPS target information database 111 that stores information relating to traffic monitoring activities, and a user status database 113 that manages post evaluation for each member.
In the storage area of the GPS target information database 111, in addition to the established GPS area that stores the established traffic information that is information of the traffic monitoring activity that has been confirmed by the system side, the posted information is temporarily stored 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 ended, and the like are provided. The posting target information in the newly arrived information area is a candidate for existing traffic information to be newly added to the existing GPS area. The GPS target information database 111 may be formed using a single storage unit such as a hard disk, or may be formed using a plurality of storage units such as a hard disk or a flash ROM.

Existing traffic information in the existing GPS area is based on the location and area of information such as traffic monitoring facilities such as installed orvis, past traffic control activities such as seat belt control and drinking inspection, and the frequency of accidents. This is driving support information (POI data) that is a combination of position information representing.
The posting information in the posting area is unprocessed information that has been posted from the mobile terminal 2. Although details will be described later with reference to FIG. 17, in this posting area, posting information for each traffic monitoring activity is managed in a list in the order of posting.
Posting target information in the distribution area is information on which the distribution is being continued and integrated with a plurality of pieces of post information common to traffic monitoring activities.
The posting target information in the new arrival information area is past posting target information for which distribution has ended. This post target information may be newly registered as existing traffic information after receiving a confirmation work by an administrator on the system side. For example, when post information related to an unregistered N system (car number reading system) is stored as the existing traffic information, the system staff visually confirms it on site and then newly registers the existing traffic information. Operation is possible. For example, when post information and post target information related to unregistered inspections are frequently recorded as the existing traffic information, the administrator on the system side can consider registration as the existing traffic information according to the frequency or the like.

  In addition, instead of the posting server 11 of this example having both a function of receiving posting information, a function of generating posting target information, and a function of distributing posting target information, each function may be configured by a separate server. good. Servers having these functions individually may be connected in a communicable state and may be installed in the same place, but may be installed in different places.

(Mobile device)
As shown in FIGS. 5 and 6, the mobile terminal 2 of the present example is a palm-sized flat smartphone (multifunctional mobile phone). Most of the front is occupied by the touch panel 21 in which the touch sensor sheet 211 is laminated on the display screen of the liquid crystal display unit 212 (FIG. 8), and the home button 2H for displaying the home screen (not shown) on the touch panel 21. Is arranged only on the side of the touch panel 21. On the back surface of the portable terminal 2, a lens hole 220 fixed to a camera substrate 22 (FIG. 8) that constitutes an imaging unit is provided. Although not shown in FIGS. 5 and 6, the power button 200 (FIG. 8) and the like are arranged on the outer peripheral side surface. In the driving support system 1 of the present example, as shown in FIG. 7, a state where the portable terminal 2 is fixed to the dashboard of the vehicle using the in-vehicle holder 19 or the like is a preferable usage mode.

  As shown in FIG. 8, a control board on which an electric circuit forming the control unit 20 is formed is accommodated inside the mobile terminal 2. For the control unit 20, in addition to the camera substrate 22 on which a CMOS element, a lens, and the like are mounted, the amplifier substrate 23 that drives the speaker 230, the power button 200, the touch sensor sheet 211, the liquid crystal display unit 212, and the wireless transceiver 241. The GPS receiver 242, the clock unit 243, and the like are electrically connected.

  The wireless transceiver 241 is means for executing wireless communication in a predetermined frequency band. The wireless transmitter / receiver 241 of this example can transmit and receive digital voice data in which telephone voice is digitized by circuit switching, and also transmits and receives digital data such as post information, post target information, application programs, and map data by packet communication. Is possible.

  The GPS receiver 242 is a receiver that receives GPS signals flying from GPS satellites and outputs the current time, current position information (latitude and longitude), current speed, altitude, and the like. The GPS receiver 242 is incorporated in the main body of the portable terminal 2 so as to be positioned at the upper center of the back side when in a vertical posture as shown in FIG.

  As shown in FIG. 8, the control unit 20 includes a CPU 201, a ROM 202, a flash ROM 203, and a RAM 204 that are storage elements, an I / O unit 205 that forms an input / output interface, and the like. The ROM 202 stores various control programs including BIOS. 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 in addition to the telephone function and the data communication function, a map display function for displaying a map on the touch panel 21 and a post information generation function for generating post information. Realize post function to post information, alarm function for traffic monitoring activities, etc. 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 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). In the posting software installed in the portable terminal 2, the encrypted data of the member ID and the login password to be given to the registered member is incorporated. 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 input, and the information entered as encrypted data and the input information exactly match the input conditions for starting 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 input of a member ID or the like when starting the posting software.

The storage area of the flash ROM 203 is provided with a map database storing map data and a GPS target information database 111 storing GPS target information related to traffic monitoring activities. GPS target information includes established traffic information such as N system installation information, post target information received from a post server, and the like.
Map data (MAP data) can be downloaded from a server that provides a map (see FIG. 1). In this example, one of the posting software application servers 15 also serves as a map server.
The existing traffic information is stored in the GPS target information database 111 when the posting software is installed.
The posting target information is stored in the GPS target information when receiving the distribution, and then deleted when a predetermined time has elapsed.

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. The posting pin storage area can store posting pin information related to the traffic monitoring activity to be posted, up to four cases. Posting pin information is composed of the following pieces of information.
-Time information indicating the pin registration time (registration time of the posting target position) when the posting pin is registered on the map-Position information (latitude and longitude, monitoring position (posting pin registration position) where the traffic monitoring activity is performed (Registration direction with the address and the traveling direction of the vehicle reversed 180 degrees)
・ Activity content information (including type information) that indicates the type, mode, method, etc. of traffic monitoring activities

The basic operation of the mobile terminal 2 of this example will be described.
A posting software icon (not shown) is displayed on the home screen (not shown) of the mobile terminal 2 in which the posting software is installed. When the control unit 20 of the portable terminal 2 captures a touch operation on this icon, the startup splash screen 21A is displayed on the touch panel 21 as shown in FIG. 9, and then the login screen 21B is displayed. The login screen 21B is a screen for requesting input of a member ID and a login password registered on the driving support system 1 side.

  The control unit 20 verifies whether the member ID and login password input via the login screen 21B completely match the member ID and login password recorded in the posting software. When the member ID and the login password are verified, the control unit 20 switches the display on the touch panel 21 to the home screen 21C. This home screen 21C is a screen on which a map around the point of interest is displayed. In the lower part of the screen, in addition to the pin setting button 251 and the setting button 252, a WEB for guiding to a product site of a radar detector on the Internet. A guidance button 255 is arranged.

On the screen of the home screen 21C, a map display area is set so that the point of interest coincides with a predetermined position at 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 point of interest and displays the surrounding map on the home screen 21C unless a user operation for changing the point of interest is input. While the vehicle is traveling, the display area of the map is changed as needed so that the vehicle mark 250 representing the current position is located at a predetermined position at the lower center of the screen.
The “spanner” mark setting button 252 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, settings such as a warning display mode, a sound output mode, a warning order setting, and a map display mode can be changed. A pin setting button 251 adjacent 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 a posting button 253 for starting posting is added becomes the basic screen.

  As shown in FIGS. 9 and 11, the control unit 20 refers to the GPS target information database 111 when acquiring the home screen 21 </ b> C or the standby / posting screen 21 </ b> E, and acquires existing traffic information or post target information around the current position. . The control unit 20 scrolls and displays the information on the information display field 254 and displays the target icon 261 at a corresponding position on the map. In the information display field 254, character information for warning a traffic monitoring activity close to the current position is displayed. In the target icon 261 illustrated in FIG. 11, the circled H indicates the new H system, the circled N indicates the N system, and the circled P indicates parking. The display of these existing traffic information or posted target information will be described in detail later.

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

(1) Posting operation of posting information by the mobile terminal 2 The posting operation in a situation where a 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.
The user of the posting software can register the current position by touching the pin setting button 251 (FIG. 11) on the home screen 21C or the standby / posting screen 21E when witnessing traffic monitoring activities such as mobile orvis. is there. The control unit 20 that has detected the touch operation of the pin setting button 251 first acquires the time, the latitude and longitude of the current position, and the traveling direction from the GPS receiver 242 and temporarily stores them.

  The control unit 20 confirms an empty area in the posted pin storage area and stores new posted pin information in the empty area. When the posting pin 262 is registered, time information and position information forming part of the posting pin information are stored based on the temporarily stored time, latitude and longitude, and the traveling direction. The time information is a pin registration time temporarily stored. The location information is a latitude and longitude stored temporarily, a corresponding address, and a control orientation obtained by inverting the temporarily stored traveling orientation by 180 degrees. When there is no empty space in the posting pin storage area, the earliest posting pin 262 is deleted in time, and the corresponding posting pin information stored in the posting pin storage area is deleted so that there is no empty area. Secured. On the map displayed on the standby / posting screen 21E, the posting pin 262 is set at a position corresponding to the position information of the posting pin information. The posting pins 262 can be set up to a maximum of four, and numbers in order from the earliest registered time are attached. Post pin information in the post pin storage area is stored in a state in which the pin number of the corresponding post pin is associated.

  When the control unit 20 detects a touch operation on the posting button 253, the control unit 20 displays a pin list screen 21F (FIG. 12) on the touch panel 21 that displays a list of posting pin information stored in the posting pin storage area. In addition to four pin selection buttons 256 for each posting pin, a return button 257 is arranged on the pin list screen 21F. On the right side of the pin selection button 256, corresponding post pin information is displayed as text. This text display is a display of post pin information excluding activity content information of traffic monitoring activities, and includes a display of latitude / longitude, address, and control direction in addition to the pin registration time. In this example, since the control direction is set as essential information of the posted information, in FIG. 12, in addition to the unregistered 4th pin button 256, the 3rd pin button 256 whose direction has not been determined cannot be operated. It has become.

  The azimuth measurement by the GPS function of the portable terminal 2 of this example is performed by using GNSS space segments (GPS, SBAS, GLONAS, COMPASS and other artificial satellites) or radio waves broadcast from a plurality of broadcasting stations such as portable terminal base stations. Measurement by Doppler shift amount or relative method with past positioning points. After 1stFix is finished (after the first positioning is completed), it is determined when the vehicle speed reaches 10 km / h or more. After that, although the value of the measured azimuth varies according to the traveling, the azimuth measurement remains in a definite 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 non-positioning, while the posting pin 262 is not set on the map because the current position cannot be acquired. Displayed during search (not shown). Thereafter, the current position is acquired in accordance with the return to the positioning state, and the posting pin 262 is set.

When the operable pin selection button 256 (the first and second 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 ( 13 to 16) are appropriately displayed, and the 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 21 </ b> H and I are screens for selecting a traffic monitoring activity implementation mode and method. The posting screen 21J is a confirmation screen for the generated posting information. The posting screen 21K is a display screen indicating that posting has been completed.
Here, the type of traffic monitoring activity is the type of traffic monitoring activity of Orbis, N system, inspection, and control. Variations in the modes and methods of traffic monitoring activities vary depending on the type of traffic monitoring activity. For example, if it is N system, there is no variation of an embodiment or a system. On the other hand, for control, there are variations of mousetraps and mobile orvis, and for mobile orvis, there are variations such as radar type and stealth type. Whether or not the posting screens 21H and I are displayed during the posting operation differs depending on the type of traffic control activity.

  Among the posting screens 21G to 21K, the posting screens 21G, 21J, and 21K are screens that are surely passed 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 pass 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 (automobile number reading system), there is no variation of the embodiment or method, so the posting screens 21H and I are not displayed. On the other hand, as shown in FIG. 15, when the type of traffic monitoring activity is control, the implementation mode and method are subdivided, so it is necessary to display the posting screens 21 </ b> H and I and allow the user to 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 21I, and stores it in the posting pin storage area as needed. The activity content information forming part of the posting pin information is determined 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 posting button 259 is detected, the control unit 20 reads the corresponding posting pin information from the posting pin storage area, and adds the posting member information such as the member ID and the registrant ID to post information. Is generated. The control unit 20 transmits the posting information generated in this way toward the posting server 11, and switches the display on the touch panel 21 to the posting screen 21K when the transmission is completed. The posting screen 21K is displayed for a few seconds, and then the display is terminated in response to the return to the home screen 21C or the standby / posting screen 21E.

  In addition, the posting screens 21H and I excluding the posting screen 21G for selecting the mode and method of the traffic monitoring activity are provided with a selection button 258 of “other / unknown”. When this “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 and 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 portable terminal 2 of this example having such a specification, for example, even a user who does not know the difference in the method of Orbis (speed violation), the detailed level “Orbis is installed” according to the knowledge level Can be generated relatively easily. On the other hand, if the user has a high knowledge level who is familiar with the difference in the Orbis method, posting information with a high level of detail can be generated by selecting one of the methods on the posting screen 21I.

  Further, as shown in FIG. 15, if 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 are not very high in knowledge level, it may be troublesome that the posting screens 21 are drawn out one after another. On the other hand, the specification that a part of the posting screens 21 is passed as described above is not very detailed. It is also effective for the activation of posting activities.

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

(2) Posting Target Information Generation and Distribution Operation by Posting Server 11 When the posting server 11 receives posting information from the mobile terminal 2, it first requests authentication of the member management server 12. The member management server 12 that has been requested to authenticate uses the member information received from the posting server 11 to refer to the user management database 121 (FIG. 2) and determines whether or not the corresponding member exists. When the corresponding member exists effectively, the member's contributor ID is returned from the member management server 12.

  When the posting server 11 receives the authentication of 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 receiving it, and executes the receiving process for the posting information for which the posting prohibition flag is not set. In this reception process, first, the posting information is temporarily stored in association with the posting time (incoming time) of the posting information, and sorting for each traffic monitoring activity is executed. In this classification, the condition of commonality that the types of traffic monitoring activities are common, the condition of spatial proximity that is located within a radius of 100 m (predetermined range), and a predetermined time The posting area is searched for other posting information that satisfies the temporal proximity condition that the posting information has been posted within. When other posted information satisfying all the conditions can be searched, the newly accepted posted information is classified as having the same other posted information and traffic monitoring activity, and sequentially received as shown in the posted information list of FIG. The post number is assigned in order and stored in the post area. On the other hand, when past posting information that satisfies the condition of commonality of type, location proximity, and time proximity condition is not stored in the posting area, the posting server 11 A new post information list similar to that shown in FIG. 17 is generated starting from newly received post information (post number 001).

  When adding new posting information to the posting 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 post evaluation items for each contributor include items of the total number of posts, the number of correct posts, the number of incorrect posts, the correct post rate, and the overall evaluation. When the posting server 11 adds new posting information to the posting information list shown in the figure, the posting server 11 accumulates the points of the poster's comprehensive evaluation (FIG. 3) and calculates and stores the accumulated points. As will be described in detail later, this accumulated point is used as an evaluation value or the like of the accuracy of the posting target information based on the posting information. In this example, all post information is recorded as shown in FIG. 17, but instead of this, post information whose overall evaluation point is lower than the reference point is not registered in the list of FIG. It may be erased.

  The information detail level in the posted information list in FIG. 17 is a value representing the degree of detail of the activity content information included in the posted information. In the posting screens 21H and I (FIGS. 13 to 16), the detailed level of the posting information generated by making a significant selection other than the others is 3, and only one of the posting screens 21H and I is selected. Posting information generated by significant selection is detailed level 2, and posting information generated by significant selection only on the posting screen 21G is detailed level 1. Of course, for the N system in which the posting screens 21H and I are not presented without any distinction between the embodiment and the method, the information detail level of all posting information is level 1. On the other hand, there are various types, implementation modes, and methods, and the information detail level such as the mousetrap on which the posting screens 21H and I are presented varies depending on the posted information from the detailed level 1 to the level 3.

Here, a temporal proximity condition and a spatial proximity condition, which are conditions for sorting newly received post information, will be described.
The temporal proximity condition is a condition that the pin registration time of new post information is included within a predetermined time with reference to the pin registration time of preceding post information. As this predetermined time, different times are set for each piece of posted information, as shown in FIG. The posting time with a higher overall evaluation point is set as a predetermined time for the posting evaluation. In addition, whether the monitoring position is an urban area or a county, whether it is a main road, the number of vehicles in the police station jurisdiction to which the monitoring position belongs, etc. The longer the time is set, the smaller the traffic volume.

  As shown in FIG. 18, for example, after receiving the first post information, when the second post information satisfying the above two conditions of the local proximity and the commonality of the type is received, the arrival time is 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 a common traffic monitoring activity. In addition, for example, for the fifth post information that satisfies the above two conditions after receiving the fourth post information, the arrival time is after the elapse of a predetermined time set in the fourth post information. , Within a predetermined time set in the third posting information. Thereby, the 5th contribution information is classified as the 3rd contribution information and traffic monitoring activity in common like the 4th contribution information.

  The positional proximity condition is a condition that the position based on the new post information is included within a radius of 100 m centered on the reference point. As shown in FIG. 19, the position of the reference point fluctuates at any time as post information is sequentially sorted. Here, B1, B2, B3,... Represent post information before the corresponding post target information is distributed, and A1, A2, A3,. Represents post information. The numbers following A or B indicate the order of posting. For example, the posting information of B1 is posting information that is the starting point of posting first. A1 is the posting information posted first after the corresponding posting target information is distributed. The vertical direction in the figure represents the transition of time. The left-right direction represents the position in the forward / backward direction on the road where the traffic monitoring activity to be posted is performed. 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 a starting point, the posting server 11 first sets the corresponding monitoring position as the first reference point 1 (the circled point 1 in FIG. 19). Thereafter, when new posting information B2 relating to a traffic monitoring activity having a common type as a monitoring position within the radius of 100 m centered on the reference point 1 is received, the monitoring position of the posting information B2 and the reference point are received. A position corresponding to an intermediate point between 1 and 1 is set as a new reference point 2. When new posting information B3 relating to traffic monitoring activities with a common type is received within a radius of 100 m centered on this reference point 2 (the point of the circled circle 2), the posting information B3 is monitored. A position separated from the reference point 2 toward the monitoring position (B3) by the distance obtained by dividing the distance between the position (B3) and the reference point 2 into three equal parts is set as a new reference point 3 (point of the circled circle 3). While the reference point 2 is a point based on two pieces of posted information, the monitoring position (B3) is a point based on only one piece of posted information. Therefore, the position of the reference point 3 is based on a weighted average concept. It is determined at an intermediate position. In addition, after the reference point 3 is set in response to the reception of the posting information B3, when the posting information B4 is grouped, the distance between the monitoring position (B4) of the posting information B4 and the reference point 2 is set to 4. A position separated from the reference point 3 toward the monitoring position (B4) by the equally divided distance is set as a new reference point 3.

  Note that the weighted average coefficient is different between before and after the posting target information is distributed. Specifically, with regard to the monitoring position of post information before distribution, the weighted average coefficient is set to 1, for example, if the reference point is based on four pieces of post information, a new monitoring position and reference point Is shifted to a new monitoring position by a distance equal to five. On the other hand, with regard to the monitoring position of post information after distribution, the weighted average coefficient is set to 2, for example, if the reference point is based on six pieces of post information, the distance between the new monitoring position and the reference point is set as follows. The distance is shifted to the new monitoring position by a distance twice as much as eight.

  The reason why the handling is different before and after the distribution of the posting target information will be described. Before distribution, for any contributor, traffic monitoring activities appear unexpectedly, and it is necessary to determine the type and the like in a short time before passing. Therefore, there is a tendency that the registration operation of the point of the traffic monitoring activity is after the point, and the posted target point that is actually registered is shifted forward (in the passing direction) from the actual point. Probability is high. On the other hand, if it is after distribution, it is known in advance that the type of traffic monitoring activity related to the posting target information is being performed, so the type of traffic monitoring activity actually performed is as per the posting target information. The accuracy of determining whether or not there is a tendency to increase. In addition, while being interested in whether or not traffic monitoring activities are actually being performed at the point related to the posting target information, you will approach that point, so the registered point will be the exact point easy. Posting post-delivery where high accuracy of the monitoring position is expected by making the weighted average coefficient different when determining the reference point before and after delivery and increasing the post-delivery post monitoring point coefficient as described above Information can be quickly reflected in the position of the reference point, and the position accuracy can be improved.

The posting server 11 starts to generate post target information for distribution by integrating post information for traffic monitoring activities in which the cumulative points in the post 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 in the posted information-Location information (latitude / longitude, address, direction) of the monitoring location where traffic monitoring activities are carried out
・ Activity content information that indicates the type, mode, and method of traffic monitoring activities ・ Accuracy information that indicates the degree of likelihood of post target information

In the position information of the posting target information, the latitude and longitude of the average position of the latest 10 posting information, the address corresponding to the latitude and longitude, and the average direction of the latest 10 posting information are set. . Note that the reference point (FIG. 19) for determining the local proximity may be set to the latitude / longitude and address in the position information included in the posted information.
In generating the activity content information of the posting target information, the posting server 11 refers to the posting evaluation for each contributor (FIG. 3), the overall evaluation score is 7 points or more, and the correct posting rate is Select post information from more than 70% of contributors. If the difference in the activity content information of the selected posted information is only the difference in detail level and there is no difference in the implementation mode or method, the activity content information of the posted information with the highest detail level is left as it is. Set to activity content information to be included in target information. On the other hand, when there is a difference in the embodiment, the method, etc., the activity content information determined by majority decision is included in the posting target information. If it is not decided by majority decision, priority is given to the activity content information by the contributor who is detailed and has a high correct posting rate among the selected posting information.
The latest accumulated points are set as they are in the accuracy information of the posting 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 installation type Orvis and N system using a public communication line. To do. The posting server 11 stores the posting target information regarding the installation type Orbis and N system without distributing them, and then outputs them according to the output operation by the system administrator or the like. Posting target information that is also new information on the installation type Orbis and N system is visually confirmed by the system staff, and is registered in the existing GPS area (GPS target information database 111 in FIG. 2) when the visual confirmation is possible. The existing traffic information registered in this way is distributed to users such as radar detectors that warn of the approach to GPS content such as Orbis and N system, and then downloaded to the portable terminal 2. Included in posting software.

(3) Alarm Operation by Mobile Terminal 2 Next, alarm by the mobile terminal 2 will be described. The mobile terminal 2 of this example can execute an alarm using the existing traffic information incorporated in the GPS target information database 111 when the posting software is installed, and the posted target information stored in the GPS target information database 111 upon receiving the distribution. It is. Such an alarm is executed while the home screen 21C (FIG. 9) or the standby / posting screen 21E (FIG. 11) is being displayed. On the home screen 21C or the standby / posting screen 21E after receiving the posting target information, as shown in FIG. 20, the target icon 261C of the existing traffic information is displayed with a circular mark, and the target icon 261R of the posting target information (distribution information) is a rectangle. Displayed with a mark.

  The square target icon 261R of the posting target information is displayed in different colors according to the accuracy represented by the accuracy information included in the posting target information. Those with low accuracy are displayed in a cool color, and as the accuracy increases, the color changes to a warm color, 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 detecting a touch operation on the square target icon 261R, the control unit 20 of the portable terminal 2 displays a data display screen 21L that displays detailed data of the posting target information as shown in FIG. In 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 highly rated posters, the past results of similar traffic monitoring activities, and the poster list are displayed. When the control unit 20 detects a touch operation on 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. . In addition, also at the time of touch operation with respect to the circular target icon 261C corresponding to the existing traffic information, the detailed information of the corresponding existing traffic information is displayed.

  Furthermore, the mobile terminal 2 that is displaying the home screen 21C or the standby / posting screen 21E, as shown in FIGS. 22 and 23, according to the traveling of the vehicle, the monitoring position of the traffic monitoring activity of the established traffic information or the posted target information ( When the GPS target is approached, an alarm corresponding 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 the existing traffic information or post target information around the current position. The control unit 20 calculates the distance from the current location at any time for the GPS targets in the surrounding existing traffic information or the posted target information, 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 seat belt control area (monitoring area). The former is an example of an alarm for traffic monitoring activities performed at points rather than areas. The latter is an example of an alarm for traffic monitoring activities carried out in the area.
When the point of 340 m is reached to the installation position of the N system while the standby / posting screen 21E is being displayed, the control unit 20 displays a text display such as “N system 340 m” in the information display field 254 and also displays the N system. An illustration 265 representing the above is pop-up displayed on the screen.
When the control unit 20 reaches a point 340 m before the seat belt control area, the control unit 20 displays a text display such as “seat belt control 340 m” in the information display field 254 and pops up a corresponding illustration 265 on the screen. . Further, when the vehicle is traveling in the seat belt control area, that is, when the current position belongs to the area, the control unit 20 displays a text display such as “seat belt control” in the information display field 254. When the user passes through the area, that is, when the current position leaves the area, the character display in the information display field 254 is deleted, and the original standby / posting screen 21E and the like are displayed again.

  FIG. 23 is an example of an alarm when approaching the highway orbis installation position. The alarm start timing when approaching the highway orbis installation position depends on whether or not the vehicle speed at that time exceeds the speed limit. When the speed limit is exceeded, the control unit 20 displays a text display such as “Expressway Orvis 2000 m” when the vehicle reaches a point of 2000 m as shown in the left end diagram of FIG. And a corresponding illustration 265 is pop-up displayed. In addition, the control unit 20 performs a sound 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 Orvis 1000 m” in the information display field 254 when reaching the point of 1000 m trouble as shown in the central diagram of FIG. At the same time, a corresponding illustration 265 is popped up. In addition, an audio warning such as “1 km ahead, XX road, radar-type Orbis” is executed. Thereafter, when reaching a point 500 m in front, a sound such as “Camera is on the right side” is output from the speaker 230.
In addition, when you reach the point 300m just before, you will see an information display field 254 displaying text to that effect and a voice alert saying "300m away, XX road radar-type Orbis. Traveling speed is 120km". Run.

  Note that public control information may be added to the posting target information distributed by the posting server 11. In this case, notification of public control information as shown in FIG. This figure shows an example in which the text display “Seat belt enforcement week from August 1st” is scrolled and displayed in the information display field 254.

  As described above, if the mobile terminal 2 of this example is used, it is possible to generate post information including type information indicating the type of traffic monitoring activity performed to promote traffic safety and position information indicating the monitoring position. Posting to the posting server 11 is possible. The posting server 11 generates a posting target information (distribution information) including type information and position information related to the traffic monitoring activity by integrating a plurality of pieces of posting information common to the traffic monitoring activity to be posted. Other mobile terminals 2 can execute notifications, warnings, and the like using the posting target information from the posting server 11.

The post information from the mobile terminal 2 includes highly real-time information, but the accuracy of the post information varies, and there may be correct information or incorrect information. If a plurality of post information that is not true or false is distributed as such, there is a risk of confusion as to what information can be believed on 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 distribute posting target information whose accuracy is improved by integrating a plurality of posting information. This posting target information is easy-to-use and useful information in which real-time characteristics based on posting information and accuracy improved by information integration are compatible.

  In particular, in this example, post information to be integrated is sorted by determining three conditions: temporal proximity, commonality of types of traffic monitoring activities, and locational proximity. According to such sorting, posted information for a specific traffic monitoring activity can be accurately extracted. Furthermore, when the posting information sorted in this way is integrated to generate the posting target information, the posting information with high accuracy is selectively used after evaluating the accuracy of the posting information. Since the posting target information is information generated by integrating posting information with high accuracy, the accuracy is high. In addition, the posting target information generated by integrating the posting information that has undergone the accuracy evaluation is easy to evaluate the accuracy, and is easy to manage on the distributing side and the receiving side. On the distribution side, the posting target information may be selectively distributed according to the accuracy. On the side receiving the distribution of the posting target information, it is also possible to selectively perform notification or warning according to the accuracy.

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

  You may comprise so that the cancellation information to the effect that the traffic monitoring activity concerning the delivered posting target information is not being implemented can be generated as posting information. For example, a cancel 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) on the standby / posting screen 21E. good. On the posting server 11 side, the received cancellation information should be authenticated in the same manner as the posting information. When the posting target information is distributed after the cancellation information is received, information indicating that the cancellation information has been received and the number of canceled postings may be included. A cancel post display field for displaying such information may be added to the data display screen 21L of FIG. In addition, the accuracy of cancellation information is evaluated based on the number of postings of the same type of cancellation information, the percentage of highly rated posters, etc., and the distribution of the corresponding posting target information is canceled when the accuracy exceeds a predetermined threshold. It is also good to do.

In addition, after the distribution of the posting target information is finished, the original posting information may be stored in the new arrival information storage area. These pieces of post information are useful as reference information when considering whether or not to newly register post target information in the existing traffic information.
After the distribution of the posting target information is completed, it is preferable to perform the evaluation of the poster for each piece of posting information in the posting information list of FIG. 17 and reflect the evaluation result on the contents of the evaluation items. If you are a correct contributor, your post rating will get higher and higher, but if you make a wrong post, your post rating will go down and your post will be different. If the difference in the posting evaluation becomes significant, when the posting server 11 accepts the posting information, the handling can be easily determined, the integration of the integrated information becomes easy, and the accuracy of the posting target information can be improved. .
Instead of this example, while accepting posts from contributors who cannot be specified on the system side, post information of unspecified specific persons may be handled as post information with low accuracy. In this case, the number of posts can be increased.

  In this example, the display is color-coded according to the accuracy of the posting target information. In addition to this, a threshold regarding the accuracy of whether or not to display the posting target information may be adjustable by a user operation. In addition, the display mode of the posting target information with respect to the accuracy may be configured to be set by a user operation.

  In addition, it is good also as a structure which can correct the position of the posting pin 262 on a map by user operation, such as a drag | drug, after registering the posting pin 262 in the portable terminal 2 and transmitting posting information. In this case, the post correction information indicating that the position correction operation of the posting pin 262 has been performed may be included in the posting information. The posting server 11 presumes that post information including pin correction information has higher positional accuracy than post information that does not include pin correction information, and may reflect the post information in the position information of the post target information. good.

The mobile terminal 2 may be configured so that the position of the target icon 261R (FIG. 20) of the posting target information can be corrected by a user operation. Further, icon correction information indicating that the position correction operation of the target icon 261R has been performed may be included in the posted information. On the post server 11 side, post information including icon correction information is presumed to be handled with a high positional accuracy and reflected in the position information of the post target information.
The posting server 11 may be provided with a map database. If known map matching is executed using map data so that the monitoring position related to the posted information is located at a specific point, the positional accuracy of the monitoring position can be secured, and the positional accuracy of the posting target information can be improved. The specific point in the map matching may be, for example, a point on a road or a point where control or the like has been performed in the past.

  The mobile terminal 2 of this example displays a data display screen 21L that displays detailed data 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, a list of contributors is displayed in the order of time of the post information, but instead of this, contributors with high overall evaluation points may be displayed in ranking.

  In this example, as shown in FIG. 4, the points of the poster's overall evaluation are determined based on the number of correct posts and the correct posting rate, thereby evaluating the accuracy of the posted information by each poster. As alternative methods for evaluating the accuracy of the posted information, a method based on evaluation from other users, a method of evaluating according to the degree of approach of the distance to the past management position data collected in advance, and the like can be considered. For example, when the target icon 261R (FIG. 20) of the post target information is touched (for example, double-tapped), the monitoring position of the original post information integrated may be displayed. Furthermore, if the corresponding author's evaluation screen is switched and displayed by touching each monitoring position, each poster can be evaluated relatively easily from the mobile terminal 2 side.

These may be combined. A configuration in which posted information is exchanged by a method using a function corresponding to a display function or a communication function installed in a portable terminal is preferable.

  The basic operation of the alarm function, which is the main function of the radar detector 4 having the above-described configuration and realized by the control of the control unit 40 and the like, will be described. In a standby state in which an alarm target event such as RD reception, wireless reception, or alarm point approach has not occurred, a standby state is displayed in which the map screen 62 (FIG. 29) is displayed. When any one of the alarm point approach, RD reception, and wireless reception occurs in the standby state, the control unit 40 executes the corresponding function among the GPS alarm function, the RD alarm function, and the wireless alarm function. Execute the process. Note that, when two or more events occur simultaneously, the priority of each function is in order of the RD alarm function, the radio alarm function, and the GPS alarm function from the highest.

  On the map screen 62, a map around the current position is displayed as shown in FIG. On the map screen 62, the map is displayed so that the traveling direction of the vehicle always faces upward, and the lower center of the screen is the current position. The own vehicle icon 601 is displayed at the current position. In the upper left corner of the map screen 62, a compass 626 and a vehicle speed display 625 for displaying the traveling direction of the vehicle are arranged, and a time display 621 is arranged in the upper right corner. In the lower left corner of the map screen 62, an address display 622 for displaying a town name and the like at the current position is arranged.

When an alarm target event such as RD reception, wireless reception, or alarm point approach occurs in the standby state, the control unit 40 displays alarm information on the map screen 62 in a superimposed manner (pop-up display), and the alarm content is voiced. Output. At this time, the light emission color of the light emitting unit 53 changes from blue representing the standby state to red, thereby displaying that attention is required.
In the GPS alarm, as shown in FIG. 30, a photo display 628 of a control point including a symbol display 629 of alarm contents and a radar display icon (mini radar) 627 indicating the remaining distance and direction are pop-up displayed on the map screen 62.
In the RD alarm, as shown in FIG. 31, a photo display 628 of a control point including a symbol display 629 of alarm contents and a radar display icon 627 indicating the remaining distance and direction are pop-up displayed on the map screen 62. As the remaining distance of the radar display icon 627, a distance estimated from the electric field strength (Lv1 to Lv5) of the received radar wave is displayed.
Since the wireless alarm is almost the same as the RD alarm, a wireless alarm screen (not shown) is displayed.

Next, the data specification of the posted information (including posted pin information) handled by the driving support system of this example and the operation of the system will be described.
The data specification of the posted information handled by the driving support system of this example is as shown in FIG. In the figure, illustration of header information and the like necessary for communication is omitted. In the posted information of this example, the member information of the first embodiment is replaced with product information (serial number or the like) of the radar detector 4. In addition, the posting pin information of the present example includes freshness information indicating the implementation time of the traffic monitoring activity to be posted and direction type information indicating the type of the control direction (FIGS. 32 to FIG. 34) has been added. The breakdown of each data such as X, Y, A... Constituting the posting pin information in FIG. 32 is as shown in FIG. The contents of T, R, and M data among the data shown in FIG. 6A are as shown in FIGS.

The freshness information is information indicating the implementation time of the traffic monitoring activity to be posted. A data value representing freshness is defined as shown in FIG. 33 (c) in accordance with the execution time of the target traffic monitoring activity. For example, if the posted information is for traffic monitoring activities that are currently being implemented, the value of freshness will be zero, and the posted information will be for traffic monitoring activities that have been performed within one month over one week. In this case, the freshness value is 20. On the other hand, the postage information for the permanent installation type Orbis or the like has a freshness data value of 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 of the opposite lane, and to specify whether the traffic monitoring activity is the right side or the left side of the traveling lane. For example, in the case of a traffic monitoring activity for a traveling lane, 0x01 obtained by reversing the 0x02 travel direction (vehicle travel direction) in Fig. 34 by 180 degrees is the type of the control direction. For example, when a posting pin is registered in front of the Orbis installed in the median strip, Orbis is set in the diagonally right direction of the traveling lane. In this case, the type of the control orientation is the orientation of 0x10 in the figure.

  In the driving support system 1 of this example, (1) generation of post target information using the radar detector 4, (2) transmission of post information by the portable terminal 2, (3) authentication of post information by the member management server 12, These operations are different from those of the driving support system of the first embodiment. Hereinafter, the contents of the operations (1) to (3) will be described.

(1) Generation of Posting Information When the control unit 40 of the radar detector 4 detects the operation of the memory button 522 while the map screen 62 in FIG. 29 is being displayed, as shown in FIG. The registration menu button 63 is pop-up displayed 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), an ITY map button 631 for displaying the latitude and longitude of the vehicle positioning position when the button is pressed, 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 touched, the control unit 40 sets the posting pin 64 at the current position on the map screen 62 as shown in FIG. 36, and the position information (latitude / longitude, address, control orientation) 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 capable of registering a maximum of four pieces of posted pin information in the posted pin storage area, the posted pins 64 can be registered up to four pins from the first pin to the fourth pin. In the figure, since all the pins are empty, the first pin is set as the posting pin 64 at the current position, and the position information and pin registration date and time at that time are stored in association with the first pin. It is an example. Note that 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 posting pins 64 are registered and four posting pin information is stored in the posting pin storage area, the registration menu button 63 in FIG. 37 is popped up in response to the operation of the memory button 522. The Here, the registration menu button 634A including the display “Pin is full” indicates that posting pin 64 (FIG. 36) cannot be registered.
In this example, the control direction is indispensable information for the posting information. As in the first embodiment, the posting pin 64 cannot be registered when the traveling direction by the GPS function is not yet determined. Yes. When the memory button 522 is operated in a state in which the traveling azimuth has not yet been determined, the control unit 40 pops up a registration menu button 63 including a registration menu button 634B indicating the azimuth is not yet determined (FIG. 38). When the memory button 522 is operated in a non-positioning state in which positioning by the GPS function is not performed, the control unit 40 displays a telop message indicating that a GPS search is being performed on the upper part of the map screen 62 (FIG. 39). ).

  When the control unit 40 detects a touch operation on the map screen 62 (FIG. 29, etc.), it displays the uppermost setting screen 67A in FIG. Various menu buttons including a posting button 670 for posting posting information are arranged on the setting screen 67A. When the posting button 670 is touched, the control unit 40 switches to the display of the middle posting pin menu screen 67B in FIG. The posting pin menu screen 67B is a screen in which a confirmation button 671A and an erasing button 671B are arranged for each posting pin. It should be noted that the unregistered posting pin is in an inoperable state while the operation buttons 671A and B are displayed in shadow. The control unit 40 that has detected the touch operation on the pin confirmation button 671A reads the posted pin information corresponding to the posted pin from the posted pin storage area. In addition to the text display of position information (latitude / longitude, address, control direction) and time information (pin registration date / time) in the read posting pin information, the control unit 40 includes a posting button 672 and the like for starting posting processing. The arranged pin confirmation screen 67C is displayed. Posting information generation is started in response to a touch operation of the posting button 672.

  As shown in FIG. 41, when the control unit 40 detects a touch operation of the posting button 672 in the pin confirmation screen 67C, the control unit 40 appropriately displays the posting screens 67D to 67I in FIGS. 41 and 42 according to the type of traffic monitoring activity. Is displayed on the touch panel 45. The posting screens 67D to 67F in 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 method. The posting screens 67D to 67F 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 according to the user operation on the posting screens 67D to 67F to the posting pin information stored in the posting pin storage area. Note that, 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 operation buttons for selecting other and the like on the posting screens 67E and 67F is to activate posting by simplifying posting by a user who is not familiar with traffic control.

The posting screen 67G in FIG. 42 is an operation screen for inputting freshness information (FIG. 32) indicating the implementation time of the traffic monitoring activity to be posted. This posting screen 67G includes an operation button for selecting the current operation, an operation button for one week, an operation button for one month, an operation button for three months, and the like. While the driving support system 1 according to the first embodiment is a system that is supposed to post a traffic monitoring activity that is currently being implemented, the system according to the present example also allows a posting that targets a past traffic monitoring activity. It has become. The control unit 40 adds 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 enforcement direction. In this posting screen 67H, “traveling lane”, “opposite lane”, “right direction”, “left direction”, “traveling lane right side”, “traveling lane left side”, “opposite lane left side”, “opposite” Operation buttons 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.

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

  When the posting server 11 receives the posting information, it first requests authentication of the member management server 12. The member management server 12 that has been requested for authentication refers to the user management database 121 using product information (such as a serial number) received from the posting server 11 and determines whether or not the corresponding purchaser exists. When the corresponding purchaser exists effectively, the poster ID of the purchaser is returned from the member management server 12. When the posting server 11 receives the authentication of 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 receiving it, and executes the receiving process for the posting information for which the posting prohibition flag is not set.

The acceptance process of this example is different from posted information whose data value of freshness information (FIG. 33) is zero and other posted information. The freshness information is zero, that is, the real-time post information targeted for the traffic monitoring activity currently being implemented is handled in the same manner as in the first embodiment, and becomes the original information of the post target information for distribution.
On the other hand, other post information, that is, post information related to permanent traffic monitoring activities such as the N system (data value of freshness information is 255) and post information related to past traffic monitoring activities are the same as in the first embodiment of the posting server 11. It is stored in the same newly arrived information area and becomes the original information of the existing traffic information newly registered.
Other configurations and operational effects are the same as those in the first embodiment.

  The posting screens 67E to H (FIGS. 41 and 42) may be provided with “immediate posting buttons” for jumping to the posting screen 67I. If any of the Orvis button, the N system button, the control button, and the check button is selected on 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 determined. . In this way, after the type of traffic monitoring activity is confirmed, even if the posting button on the posting screens 67E to 67H is operated thereafter, the posting information including the type information indicating the determined type can be generated. .

  The registered posting pin 64 (FIG. 36, etc.) can be deleted by operating the delete button 671B on the posting pin menu screen 67B in the middle of FIG. When the delete button 671B is operated, as shown in FIG. 43A, the deletion of the corresponding posting pin is completed via the screen for confirming the deletion and the screen for displaying the completion of the deletion. If the system button arranged in the lower right corner of the setting screen 67A in the uppermost row in FIG. 40 is operated, the data erasure screen can be switched and displayed as shown in FIG. If the posting pin button is selected on this data erasure screen, the posting pin and the corresponding posting pin information can be erased collectively.

Posting target information distributed by the driving support system 1 of this example is information related to the traffic monitoring activity that is currently being implemented, as in the first embodiment. Alternatively or additionally, post target information generated by integrating post information relating to past traffic monitoring activities with freshness information (FIG. 33) other than 255 or zero may be distributed. In this case, for example, one or a plurality of posted information for traffic monitoring activities carried out two months ago, posted information for the same type of traffic monitoring activities one month ago, and the same type within one week It is possible to generate post target information related to points requiring attention with high frequency of traffic monitoring activities by integrating post information with respect to traffic monitoring activities.
In addition, in order to sort one or a plurality of posted information as posted information for common traffic monitoring activities two months ago, the temporal proximity and the spatial proximity related to the implementation time And the three conditions of commonality of types need to be satisfied. In addition, post information for traffic monitoring activities performed in the same manner one month ago with respect to post information for specific traffic monitoring activities two months ago should be Two conditions of common proximity and commonality of types need to be satisfied.

  In this example, posted information is transferred to the mobile terminal 2 using the code image 670 (FIG. 42) displayed by the radar detector 4. Instead, the radar detector 4 and the portable 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 activated on the mobile terminal 2 side, the posting information is posted via the mobile terminal 2. It is good also to comprise. In order to provide the radar detector 4 with the WiFi function, a WiFi module or the like may be incorporated. The mobile terminal 2 may be a mobile terminal having an access point (tethering) function.

  If the radar detector 4 is capable of wireless communication with the portable terminal 2, it is also possible to receive the posting target information via the portable terminal 2. The radar detector 4 can notify the posting target information, warn, and the like. Furthermore, if the public control information is distributed, the radar control information can be notified by the radar detector 4 as shown in FIG. The radar detector 4 illustrated in the figure scrolls and displays the public control information that has been distributed at the bottom of the map screen 62.

  In addition, the driving assistance system which can respond to both the contribution information of Example 1 and the contribution information of this example may be sufficient. The posting target information may be generated by integrating the posting information of the first embodiment and the posting information of this example. In this case, the evaluation of accuracy may be different between the post information generated by the mobile terminal 2 and the post information generated by the radar detector 4. For example, for a contributor who purchases and actually uses the radar detector 4, it is possible to assume a person who attaches importance to the alarm function and has a lot of knowledge about traffic control. There is a high possibility that the posting information by such a poster can be evaluated with high accuracy.

  In this example, the accumulated 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 past history of traffic monitoring activities. For example, if there is a history of similar traffic monitoring activities in the past, 120% of the accumulated points (20% higher value) are set as the accuracy, or the history points are added to the accumulated points. It is also good to do. As the history point, a point reflecting the execution frequency or the like is preferable. In determining the past implementation history of traffic monitoring activities, it is also possible to use post target information in the newly arrived information area in addition to the use of existing traffic information.

    Depending on the vehicle information acquired by the OBD function, such as the speed of the vehicle, it is also possible to change the notification or warning mode of the posted target information. For example, in the case of a speed exceeding the speed limit, post target information relating to a mobile orbit is very important.

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

Post information that is subject to distribution includes, for example, post information that the post evaluation point of the contributor is 8 points or more and has not yet been reflected in the post target information, or changes in the monitoring position such as police cars in the guard. Along with this, there is posting information and the like where real-time performance becomes important.
FIG. 45 is a display example of post information relating to a white buy being watched. In the figure, on the map displayed on the touch panel 21 of the portable terminal 2, information pins 271 are displayed at the monitoring positions corresponding to the posted information of the watched white buy. In the figure, a balloon display 275 displayed when the information pin 271 is tapped (touched) 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 post information where real-time performance is important, a limit of 6 hours or the like is set for the displayed time, the time limit is managed on the mobile terminal 2 side, and the information pin 271 is deleted as the time limit elapses. It is also good to do. Note that the illustration of the information pin 271 may be changed depending on the type of 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 posted information in which the monitoring position is not included in the map area displayed on the touch panel 21 among the posted information distributed as described above. By providing such a display, it is possible to display post information having a monitoring position in the distance that is not included in the map area. A range such as 20 km can be set as the far range. It is also possible to selectively display distant post information located in the traveling direction of the vehicle, distant post information located on a running road, and the like. Note that the public control information of FIG. 24 referred to in the first embodiment may be displayed in the scroll display column 278. In this case, the post information such as changing the background color between the public control information and the post information may be used. It is advisable to devise to make it easy to distinguish between public control information.

  For example, the configuration shown in FIG. 46 can be adopted as the message configuration when the posted information is scroll-displayed. In the case of such a message structure, for example, “Yuppi-san (35) 10:30 on June 6 [Radar control] In front of Jupiter, Iwatsu-cho, Okazaki-shi, Aichi Prefecture. "Can be scrolled. The posting experience value is preferably a value that increases in proportion to the number of postings. For example, you may employ | adopt the positive posting number, comprehensive evaluation, etc. which are shown in FIG. 3 as contribution experience value. In order to increase the number of users such as posting enthusiasts who like posting, events such as awarding the top 3 posting experience points and giving prizes are also effective. It is also possible to provide the posting server with a program that selects the top 3 posting experience values at the end of the year. Such an event serves as an incentive for posting and contributes to more accurate collection of posting information.

  Post information may be automatically distributed from the posting server (for example, every 10 minutes). As shown in FIG. 45, an update button 272 may be provided, and distribution may be performed immediately in response to an operation of the update button 272. Further, the posting information may be selectively distributed only to a desired user. This is because there are users who do not wish to distribute post information with insufficient accuracy.

In order to distribute the posted information, it is also possible to use a distribution file for each 47 prefectures. If such a distribution file is used, for example, post information in the prefecture can be distributed to users traveling in Aichi prefecture in a lump. When distributing 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 simultaneously. Furthermore, the posting information included in the distribution file may be limited to posting information within six hours from the posting time (time accepted by the posting server). The post information for one case may be, for example, the following contents.
・ Latitude / Longitude Example, 34.794025 degrees, 137.1117188 degrees ・ Display period Example, June 6, 2012 10:25 to June 6, 2012 16:25 ・ Regulation details Example, speed control (white buy)
・ Address information Prefectural example, Aichi prefecture, municipality name, Nishio city, street address, etc., XX town, 2 address ・ Detailed location and nearby landmarks (data may not be available)
For example, a road and comment from the intersection between JA of Nishimurozu and Sugi Pharmacy towards Koda (data may not be available)
For example, it ’s a place you ’re doing. Watch out for the speed limit of 40km.
・ User information User name Example, Yuppi Posting experience value Example, 121

In the mobile terminal 2 of this example, generation of post information can be started by a touch operation of the post button 273 in FIG. When the posting button 273 is touched, a posting page (not shown) is displayed. This posting page includes an operation means such as a rotating drum for selecting the type of traffic monitoring activity in addition to the text display of latitude / longitude, year / month / day / hour / minute and address information when the posting button 273 is touched. It is also possible to provide a picker view. For detailed locations and comments, text should be entered. It should be noted that the detailed location and comments may be allowed to pass so as to be able to deal with contributors who are troublesome in text input. If a comment or the like is passed, a nice comment may be added on the posting server side.
Other configurations and operational effects are the same as those in the first embodiment.

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