[Overview of traffic obstacle notification system]
FIG. 1 is a block diagram for explaining an overall configuration example of the traffic obstacle notification system of this embodiment. The traffic failure notification system of this embodiment is configured by connecting a mobile communication terminal 1 and a traffic failure notification server 2 via a communication network 4. In addition, traffic information providing servers 3 (1), 3 (2), ... Are also connected to the communication network 4. The communication network 4 is mainly the Internet, but is a mobile phone network that connects a terminal such as a mobile communication terminal 1 or a server such as a traffic failure notification server 2 to the Internet, a wireless LAN (Local Area Network), and a public switched telephone. Including net etc.

In this embodiment, the mobile communication terminal 1 is realized by a high-performance mobile phone terminal called a smartphone or the like. In addition to this, it is also possible to realize the mobile communication terminal 1 by a mobile phone terminal, a tablet PC (Personal Computer), or the like. As will be described in detail later, the mobile communication terminal 1 is provided with a current positioning function such as GPS (Global Positioning System), and is located at a place that serves as a base in daily life, such as a home or an office at work. Information (base location) is stored in memory. The base position is automatically determined using so-called daily area determination data, or is manually set and registered by the user.

Further, the mobile communication terminal 1 can specify the moving means used when the user who owns the mobile communication terminal 1 moves, and can store and hold information indicating the specified moving means. The moving means can be automatically determined and specified by a predetermined method using the moving speed, the output of the sensor included in the mobile communication terminal 1, and the like. Then, when the current position of the own device is a position some distance from the base position, the mobile communication terminal 1 indicates information indicating the current position, the base position, and the transportation means used to reach the current position. It has a function of notifying the traffic obstacle notification server 2 of the search information including the above.

The traffic obstacle notification server 2 includes a notification device unit 210 and a route search device unit 220. The notification device unit 210 sets a route search condition based on the search information from the mobile communication terminal 1, and supplies the route search condition to the route search device unit 220. Here, the route search condition is such that the current position, the base position, and the means of transportation included in the search information are set to the starting point, the destination, and the means of transportation. The route search device unit 220 is based on the departure point (current position), destination (base position), and transportation means of the route search condition from the notification device unit 210, and is from the departure point (current position) by the movement means. Search for one or more routes (routes) when moving to the destination (base position).

Further, the route search device unit 220 refers to information such as the traffic information providing servers 3 (1), 3 (2), ..., Which are connected to the communication network 4, and causes a traffic obstacle for one or more routes searched. Search for a situation. In this embodiment, for example, the traffic information providing server 3 (1) provides information on road conditions, and the traffic information providing server 3 (2) provides information on public transportation such as trains and buses. Is what you do. In addition to this, a traffic information providing server that provides information on transportation such as aircraft and ships is also provided.

Then, the route search device unit 220 searches the traffic information providing server 3 (1) for the status of traffic obstacles such as the occurrence or elimination of traffic congestion or traffic closure for the route when the means of transportation is an automobile. In addition, the route search device unit 220 searches for the status of traffic obstacles such as suspension of driving of public transportation and occurrence or elimination of delays through the traffic information providing server 3 (2) for the route when the means of transportation is walking. To do. Then, the search result is provided to the notification device unit 210. The notification device unit 210 uses the search information used this time when a traffic failure occurs or when the traffic failure that has occurred is resolved based on the search result of the traffic failure status from the route search device unit 220. Is transmitted to the mobile communication terminal 1 of the transmission source of.

As a result, when the user of the mobile communication terminal 1 is in a place other than the base such as his / her home or office, the situation of traffic obstacles on the route for returning to the base from the place other than the base can be checked. It can be obtained by the so-called push method without any special operation. That is, it is possible to obtain the situation of a traffic obstacle such as the occurrence of a traffic obstacle on the route for returning to the base from a place other than the base and the elimination of the traffic obstacle without any operation.

If there are multiple bases for users of the mobile communication terminal 1, such as home and offices at work, the current time is taken into consideration when the users are usually present at the bases. In, it is possible to determine which base to return to. Of course, it is also possible for the user of the mobile communication terminal 1 to set a base to return to in advance.

In the following, a configuration example of the mobile communication terminal 1 and the traffic fault notification server 2 of the traffic fault notification system of this embodiment, and the details of the processing performed in each of them will be described. Although only one mobile communication terminal 1 is shown in FIG. 1, in reality, a large number of mobile communication terminals used by each of a large number of users are connected to the traffic failure notification server 2 via the communication network 4. Connected to. Although there are various types of these mobile communication terminals, since the basic functions are the same, the mobile communication terminal 1 will be described as a configuration example of these various mobile communication terminals.

[Configuration example of mobile communication terminal 1]
FIG. 2 is a block diagram for explaining a configuration example of the mobile communication terminal 1 of this embodiment. In the mobile communication terminal 1 shown in FIG. 2, the transmission / reception antenna 101A and the wireless communication unit 101 realize a communication function. Although not shown, the control unit 102 is a computer device unit configured by connecting a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) via a bus, and is a mobile communication terminal 1. Realize the function to control each part. The operation unit 103 is a portion provided with a power on / off switch, some function buttons, and the like.

The storage device 104 includes a non-volatile memory having a relatively large storage capacity such as a flash memory, and writes data to the memory, stores the data, reads data from the memory, and stores the data in the memory. Delete data, etc. Then, in the memory of the storage device 104, for example, the map data and the road network data provided by the map information providing server are stored and held so that the navigation function can be realized. Further, in the mobile communication terminal 1 of this embodiment, a base information file and a current location information file are provided in the memory of the storage device 104.

FIG. 3 is a diagram for explaining an example of stored data of the base information file provided in the memory of the storage device 104. As shown in FIG. 3, the base information file contains the base location (representative point) of the place where the user of the mobile communication terminal 1 is usually staying for a long time, such as a home or an office at work. ), Latitude, longitude, staying time zone, staying day of the week, and type are stored in memory. These base location information can be acquired by automatic determination using daily area determination data and map information.

That is, the daily area determination data consisting of the current position and the current time is acquired and accumulated at predetermined timings, and these are compared with the map information. And if the place where you often stay from night to morning is a house, that place is your home, and if the place where you often stay from morning to night is an office building, that place is It can be determined that it is the office where you work. Of course, since the base does not change frequently, the user may manually register each information in the base information file shown in FIG. 3 of the mobile communication terminal 1 in advance.

FIG. 4 is a diagram for explaining an example of stored data of the current position information file provided in the memory of the storage device 104. As shown in FIG. 4, the current position information file stores the latitude and longitude indicating the current position and the information indicating the moving means used to reach the current position. Here, the current position is acquired at predetermined timings by the GPS function provided in the mobile communication terminal 1. Further, the information indicating the moving means can be automatically determined based on the information such as the current position, the moving speed, the sensor output, and the moving route that can be detected by the mobile communication terminal 1. If the current position acquired at each predetermined timing does not change, the data content of the current position information file is maintained.

Further, each time the current position is acquired, the moving speed acquires the current time corresponding to the acquisition timing through the clock function described later and holds it as information paired with the current position. As a result, the moving distance between the past current positions can be known according to the acquired past current position, and the moving time between the past current positions can be known according to the current time corresponding to the past current position. As a result, the moving speed of the section can be obtained by dividing the moving distance by the moving time.

Then, for example, when the speed is less than 7 km / h and the detection output from the vibration sensor is periodic according to walking, it can be determined that the means of transportation is walking. Further, if the vehicle travels at a speed of 8 km / h or more for a certain period of time or more and the detection output from the vibration sensor is not periodic according to walking, it can be determined that the moving means is an automobile. In this case, if the movement route is a railway line, it can be determined that the movement is by train, and the means of transportation can be determined to be walking. In addition, even if the latitude route is a road, if the vehicle is moving so as to stop at the place where the bus stop is installed, it can be determined that the movement is by a fixed-route bus, and the means of transportation can be determined to be walking. ..

The clock circuit 105 has a calendar function and provides the current date, the current day of the week, and the current time. The sensor unit 106 includes various sensors such as a 6-axis sensor, a geomagnetic sensor (azimuth sensor), and a vibration sensor. The 6-axis sensor is a combination of a 3-axis acceleration sensor and a 3-axis gyro sensor, and can accurately detect the attitude of the own aircraft. In addition, the geomagnetic sensor can accurately detect the azimuths such as north, south, east, and west with reference to the own machine. In addition, the vibration sensor can detect the vibration applied to the own machine.

By the function of the sensor unit 106, it is possible to detect the posture of the own machine and the traveling direction (moving direction) of the own machine. As a result, it is possible to display a navigation map on the display unit 108D so that the upper side of the display screen of the display unit 108D viewed by the user is the traveling direction of the own machine. Further, it is possible to detect the vibration generated during walking and use it for determining the means of transportation, or to realize the function of the pedometer.

The GPS antenna 107A and the GPS unit 107 realize the current position acquisition function. The touch panel 108 including the display unit 108D and the touch sensor 108S, the audio output unit 109, and the speaker 110 form a user interface. The display unit 108D can display a map and the current position of the own machine, and can display necessary guidance information. In addition, various guidance messages, alarm sounds, and the like can be emitted through the voice output unit 109 and the speaker 110.

The traffic obstacle notification unit 120 includes a search information forming unit 121 and a notification control unit 122, and realizes a function of notifying when a traffic obstacle occurs in the route from the current position to the base. The search information forming unit 121 functions when the current position of the own machine is a position some distance from the base position of the base information file formed in the memory of the storage device 104. The search information forming unit 121 forms the search information and transmits the search information to the traffic failure notification server 2 through the wireless communication unit 101 and the transmission / reception antenna 101A.

FIG. 5 is a diagram for explaining an example of the search information formed by the search information forming unit 121. As shown in FIG. 5, the search information includes a terminal ID, a current position, a base position, a means of transportation, and the like. The terminal ID is information that can uniquely identify the mobile communication terminal 1, and for example, the IP (Internet Protocol) address of the mobile communication terminal 1 is used. The current position is the current position of the mobile communication terminal 1, and the moving means is the moving means used to reach the current position. As the current position and the moving means, the current position and the moving means of the current position information file described with reference to FIG. 4 are used.

Further, the base position of the search information is information indicating the position of the base to be returned from the current position, and the base position of the base information file described with reference to FIG. 3 is used. However, if there are two or more bases, it is automatically determined which base should be headed at the present time based on the current time and the staying time zone of each base. For example, a case where the data of the base information file shown in FIG. 3 is used will be described as an example.

Simply, if the current time belongs to the staying time zone of any of the bases, the base of the staying time zone to which the current time belongs may be determined as the base to be returned. In this case, the time zone other than the staying time zone is considered to be the commuting time from the home to the work place and the return time from the work place to the home, and should not be used for determining the base. Of course, this is just an example, and other discrimination methods may be used.

For example, if the current time is after the end of the staying time zone of the office (after 20:00) and until the end of the staying time zone of the home (until 6:30), the base location is (until 6:30). In X1, Y1), it is determined that the base whose type is home is the base to be returned. This is a case of considering that many people go out to eat with colleagues after the work is completed. It is possible to make adjustments in the same way when it is determined that the base to be returned is the place of employment.

In addition, as other information, various necessary information can be added to the search information and transmitted. For example, search conditions set by the user of the mobile communication terminal 1, for example, when the means of transportation is an automobile, search conditions such as toll road priority, down road priority, distance priority, and time priority can be added. In addition, when the means of transportation is walking, search conditions such as train priority, bus priority, route priority that does not get wet in the rain, and the availability of taxis can be added. These search conditions may be registered in advance by the user of the mobile communication terminal 1 in the memory of the storage device 104 of the mobile communication terminal 1.

In addition, it is also possible to include information such as the transmission date and time information of the search information and the MAC (Media Access Control) address of the mobile communication terminal 1 in the search information as other information for transmission. In this embodiment, for the sake of simplicity, it is assumed that various search conditions are not transmitted by other information. Then, as shown in FIG. 5, the current position of the search information is used as the starting point, the base position is used as the destination, and the moving means is used as the moving means when going from the starting point to the destination. ..

Such search information is transmitted from the mobile communication terminal 1 to the traffic failure notification server 2. Then, based on the search information, the traffic obstacle notification server 2 searches for the traffic obstacle status on the route from the current position (departure point) to the base position (destination) by the transportation means, and notifies the search result. Will be done. Here, the situation of the traffic obstacle includes at least the occurrence of the traffic obstacle, the change of the traffic obstacle, and the elimination of the traffic obstacle.

If the same traffic obstacle is repeatedly detected at the same location, it can be determined that the traffic obstacle that has occurred continues. In addition, changes in traffic obstacles include, for example, an increase or decrease in a congested section in the case of road congestion, a change from a suspension of driving to a delay, an increase or decrease in delay time, etc. in the case of a railway line. including.

The notification control unit 122 performs notification processing according to a failure notification described later from the traffic failure notification server 2 received through the transmission / reception antenna 101A and the wireless communication unit 101. The notification control unit 122 performs a process of notifying, for example, that a traffic obstacle has occurred, a change in the traffic obstacle that has occurred, or a resolution of the traffic obstacle that has occurred. If the traffic obstacle that has occurred continues, the occurrence of the traffic obstacle will not be repeatedly notified for the same route.

As described above, the mobile communication terminal 1 of this embodiment cooperates with the traffic obstacle notification server 2 when the current position is separated from the base position to some extent, and describes the situation of the traffic obstacle in the route returning from the current position to the base. , You can receive notifications by push method. If the current position is separated from the base to some extent, it usually means that it cannot be easily moved without using a car or public transportation, and the linear distance from the current position to the base position is, for example, 2 km or more. It is stipulated as a case.

Of course, the criterion when the current position is separated from the base to some extent is not limited to the case where the straight line distance from the current position to the base position is 2 km. The distance serving as the determination criterion can be set to an appropriate distance, such as 3 km or 4 km, depending on the user of the mobile communication terminal 1.

Also, instead of the distance between the current position and the base position, it is judged that the current position is located in a different city, ward, town, or village from the city where the base is located, as if the current position is some distance from the base. You may. Further, the case where the current position is located in a prefecture different from the prefecture where the base is located may be determined as the case where the current position is separated from the base to some extent. In addition to this, the case where the current position is separated from the base to some extent may be determined by various methods.

The process shown in FIG. 7 is always executed by the control unit 102 of the mobile communication terminal 1 at predetermined timings until the current position of the mobile communication terminal 1 is separated from the base to some extent (for example, 2 km in a straight line distance). To. Then, when the current position of the mobile communication terminal 1 is separated from the base to some extent (for example, 2 km in a straight line distance), the search information transmission process and the notification information reception process continue until the base is reached or, for example, the end operation is performed. Will be done. Hereinafter, a specific description will be given.

First, the control unit 102 identifies a base to return to at the present time (step S101). Specifically, in step S101, the stored data of the base information file formed in the memory of the storage device 104 should be referred to, and if there is only one base data, the base specified by the base data should be returned. Identify as a base. When there are a plurality of base data, the control unit 102 compares the current time acquired from the clock circuit 105 with the staying time zone of each base data in the base data file to specify the base to be returned (step S101). ). In this embodiment, as described above, when the current time belongs to the staying time zone of any of the bases, the base of the staying time zone to which the current time belongs is determined as the base to be returned.

Next, the control unit 102 acquires the current position of the own machine through the GPS unit 107 (step S102), and determines whether or not the current position is separated from the base position of the specified base by a predetermined distance or more (step S103). .. Specifically, on the map, the current position and the base position of the base to be returned are plotted on the map, the straight line distance between these two points is obtained, and the straight line distance should be separated by, for example, 2 km or more. For example, it can be determined that the current position is separated from the base position of the specified base by a predetermined distance or more.

It is assumed that in the determination process of step S103, it is determined that the current position is not separated from the base position of the specified base by a predetermined distance or more. In this case, since the user having the mobile communication terminal 1 is located at or near the base, the control unit 102 ends the process shown in FIG. 7 and waits for the next execution timing. ..

It is assumed that in the determination process of step S103, it is determined that the current position is separated from the base position of the specified base by a predetermined distance or more. In this case, the control unit 102 accesses the traffic failure notification server 2 through the wireless communication unit 101 and the transmission / reception antenna 101A, and connects the link (communication path) (step S104). Then, the control unit 102 controls the search information forming unit 121 to start the search information transmission process (step S105). The details of the search information transmission process started in step S105 will be described later. Further, the control unit 102 controls the notification control unit 122 to start the notification information reception process (step S106). Details of the notification information reception process started in step S106 will be described later.

Then, the control unit 102 confirms the end (step S107). In this step S107, it is confirmed whether or not the linear distance between the latest current position and the base position of the base to be returned is shorter than, for example, 2 km. If the straight line distance between the latest current position and the base position of the base to be returned is shorter than 2 km, it can be determined that the user having the mobile communication terminal 1 has reached the vicinity of the base, and the traffic failure notification process is terminated. Confirm (identify) that it has become. Further, it is confirmed (specified) that the traffic obstacle notification process is terminated even when the predetermined interrupt process for terminating the traffic obstacle notification process is performed on the mobile communication terminal 1.

After that, the control unit 102 determines in the end confirmation process of step S107 whether or not it has been confirmed (specified) that the traffic obstacle notification process has been terminated (step S108). When it is determined in the determination process of step S107 that it has not been confirmed (specified) that the traffic obstacle notification process has been terminated, the process from step S107 is repeated.

Further, it is assumed that it is determined in the determination process of step S108 that it has been confirmed (specified) that the traffic obstacle notification process has been terminated. In this case, a predetermined termination process is executed (step S109), and the process shown in FIG. 7 is terminated. Then, the control unit 102 returns to the state of executing the process shown in FIG. 7 at predetermined timings.

The end process of step S109 includes, for example, a process of opening a link (communication path) connected to the traffic failure notification server 2. In addition, processing such as issuing an end instruction for ending the search information transmission process started in step S105 and issuing an end instruction for ending the notification information receiving process started in step S106 is also included.

[Explanation of search information transmission process]
FIG. 8 is a flowchart for explaining the search information transmission process executed in step S105 of the traffic obstacle notification process shown in FIG. 7. The process shown in FIG. 8 is a process executed by the search information forming unit 121 functioning under the control of the control unit 102. The search information forming unit 121 forms the search information described with reference to FIG. 5, and performs a process of transmitting the search information to the traffic obstacle notification server 2 (step S201). Next, the control unit 102 confirms whether or not the end instruction of the search information transmission process has been generated in the process of step S109 of FIG. 8 (step S202).

Then, the control unit 102 determines whether or not the end instruction has been generated (step S203). When it is determined that the end instruction has not occurred in the determination process of step S203, the process from step S201 is repeated. Further, in the determination process of step S203, when it is determined that the end instruction has occurred, the search information transmission process shown in FIG. 8 is terminated. As described above, the search information transmission process shown in FIG. 8 has been described with reference to FIG. 5 at predetermined timings when the current position of the mobile communication terminal 1 is separated from the base to be returned by a predetermined distance or more. This is a process of forming search information and transmitting it.

[Explanation of notification information reception process]
FIG. 9 is a flowchart for explaining the notification information reception process executed in step S106 of the traffic obstacle notification process shown in FIG. 7. The process shown in FIG. 9 is a process executed by the notification control unit 122 functioning under the control of the control unit 102. The notification control unit 122 receives the failure notification addressed to the own machine from the traffic failure notification server 2 (step S301), and determines whether or not the failure notification addressed to the own machine has been received (step S302). ). When it is determined by the determination process of step S302 that the notification of the failure or the like has been received, the notification control unit 122 executes a process of outputting the notification (step S303).

In step S303, for example, an alarm sound is emitted and message information indicating a traffic obstacle situation is displayed on the display unit 108D. For example, if the means of transportation is a car, for example, "Traffic congestion on National Highway XX, 1km due to an accident at an intersection", "Elimination of traffic congestion on National Highway XX", etc. Etc. will be notified. In addition to this, it is also possible to notify the occurrence of road closures and instructed detours. In addition, if the means of transportation is walking, obstacles such as "JR XX line, currently suspending operation due to traffic light failure", "JR XX line, restarting operation. Delay of about 30 minutes occurs" You will be notified of the occurrence of the problem and the status of the failure.

Then, after determining that the notification process of step S303 and the determination process of step S302 have not received the notification of the failure or the like addressed to the own machine, the process proceeds to the process of step S304. In this case, the control unit 102 confirms whether or not the end instruction of the notification information reception process has been generated in the process of step S109 of FIG. 8 (step S304). Then, the control unit 102 determines whether or not the end instruction has been generated (step S305).

When it is determined that the end instruction has not occurred in the determination process of step S305, the process from step S301 is repeated. Further, in the determination process of step S305, when it is determined that the end instruction has occurred, the notification information reception process shown in FIG. 9 is terminated. As described above, the notification information receiving process shown in FIG. 9 responds to the transmission of the search information from the own device when the current position of the mobile communication terminal 1 is separated from the base to be returned by a predetermined distance or more. , The notification information transmitted from the traffic trouble notification server 2 is received. Then, when the notification information is received, it is automatically output to perform a process of notifying the user of the mobile communication terminal 1.

[Processing of traffic failure notification server 2]
FIG. 10 is a flowchart for explaining an example of the traffic obstacle notification process executed by the traffic obstacle notification server 2 of this embodiment. The process shown in FIG. 10 is a process that is always performed by the functions of the notification device unit 210 and the route search device unit 220 under the control of the control unit 202 of the traffic failure notification server 2.

First, the control unit 202 receives the search information from the mobile communication terminal 1 through the communication I / F 201 (step S401), and determines whether or not the search information has been received (step S402). In the determination process of step S402, when it is determined that the signal has not been received, the process from step S401 is repeated. When it is determined in the determination process of step S402 that the search information has been received, the search condition setting unit 211 sets the search condition based on the received search information under the control of the control unit 202, and the set search condition is set. Is provided to the route search unit 221 (step S403).

In step S403, the search condition setting unit 211 sets search conditions in which the current position, the base position, and the moving means of the search information from the control unit 202 are the starting point, the destination, and the moving means, and routes the search conditions. It is supplied to the search unit 221. Under the control of the control unit 202, the route search unit 221 executes a route search according to the search conditions from the search condition setting unit 211, and provides the search result to the traffic obstacle search unit 222 (step S404).

Under the control of the control unit 202, the traffic obstacle search unit 222 searches for the traffic obstacle status in each of the one or more routes searched by the route search unit 221 and supplies the search result to the obstacle notification forming unit 212. (Step S405). Specifically, in step S405, the traffic obstacle search unit 222 accesses the traffic information providing server 3 (1), ... On the communication network 4 through the communication I / F 201, and searches for the status of the traffic obstacle in the searched route. To do.

The obstacle notification forming unit 212 first determines the occurrence of a traffic obstacle based on the search result from the traffic obstacle search unit 222 (step S406). The obstacle notification forming unit 212 holds the search result of the previous traffic obstacle status for each route, and if it is the same as or different from the previous search result, it means that a traffic obstacle has occurred or that the traffic obstacle has occurred. Determine if it is resolved. Here, the occurrence of traffic obstacles shall include the case where the traffic obstacles that are occurring have changed. For example, when the distance of the traffic congestion that has occurred becomes longer or shorter, it is considered that a new traffic obstacle has occurred. Similarly, if there is a delay from the suspension of train operation to the resumption of operation, it is considered that a new traffic obstacle has occurred.

Then, the failure notification forming unit 212 determines whether or not the determination result is the same as the previous search result (step S407), and if they are the same, the situation has not changed from the previous time, so nothing is notified. The process from step S401 is repeated without doing so. When it is determined in the determination process of step S407 that it is not the same as the previous search result, it is determined whether or not the determination result is the occurrence of a traffic obstacle (step S408).

It is assumed that in the determination process of step S408, it is determined that the determination result is the occurrence of a traffic obstacle. In this case, the failure notification forming unit 212 forms a failure notification for notifying the occurrence of a traffic failure based on the search result this time, and transmits this to the mobile communication terminal 1 of the search information provider (step). S409). After that, the process from step S401 is repeated.

Further, it is assumed that in the determination process of step S408, it is determined that the determination result is not the occurrence of a traffic obstacle. In this case, the obstacle notification forming unit 212 determines that the change is to resolve the traffic obstacle, and forms a fault notification notifying the resolution of the traffic obstacle based on the previous and current search results. This is transmitted to the mobile communication terminal 1 that provides the search information (step S410). After that, the process from step S401 is repeated.

In this way, the traffic failure notification server 2 searches for a route based on the search information from the mobile communication terminal 1, searches for the status of the traffic failure on the searched route, and uses this as the source of the search information. It is possible to notify the communication terminal 1.

[Effect of Embodiment]
In the traffic obstacle notification system of the above-described embodiment, when the vehicle is separated from a base location such as a home or an office at work by a predetermined distance and the route to return to the base is obstructed, the so-called traffic obstacle notification system is called. The user of the mobile communication terminal 1 can be notified by the push method. Further, even when the traffic obstacle is changed or resolved, the user of the mobile communication terminal 1 can be notified of this by a so-called push method. Since the notification is a push type, the user of the mobile communication terminal 1 does not need to operate the mobile communication terminal 1 in order to receive the notification of the occurrence or resolution of the traffic obstacle.

Therefore, when a traffic obstacle occurs on the route used when returning to the base, it is possible to know this in a timely manner. This makes it possible to prevent inconveniences such as being caught in a traffic jam or waiting for a train at a station for a long time without knowing the occurrence of a traffic obstacle. Then, it is possible to make effective use of time, such as searching for another route to return to the base with a margin, or detouring to another place to finish the work.

It is possible to respond by displaying the message on the screen or emitting a corresponding voice message from the speaker 110 through the voice output unit 109.

Further, for example, when the operation of the train is suspended, the route of traveling by another means of transportation such as a bus may be more convenient for the user of the mobile communication terminal 1. Therefore, the mobile communication terminal 1 forms and transmits a route search request that does not specify the means of transportation to the traffic failure notification server 2. Then, the traffic obstacle notification server 2 searches for a plurality of routes to be moved by various means of transportation from the current position of the mobile communication terminal 1 to the base, and notifies each route and the presence or absence of a traffic obstacle. You may. In this case, the user of the mobile communication terminal 1 can select a route that can be moved by a means of transportation that is more convenient for him / her.

Further, by enabling the selection of another route, it is possible to start the navigation process so as to guide the selected route. That is, it can be configured to execute the notification of the occurrence of a traffic obstacle, the selection of another route, and the navigation process of the selected route as a series of processes. In this case, map information, road network data, pedestrian network data, and transportation network data for guiding the selected route are acquired from the traffic obstacle notification server 2 and stored in the storage device 104. Then, the control unit 102 functions to display a map corresponding to the map information stored in the storage device 104 on the display unit 108D, indicate the route selected on the map, and display the own machine on the map.
