Description

  The present invention relates to a route guidance system and a route guidance server that provide route guidance from a current location to a destination in response to a request from a user of a mobile terminal device, and in particular, a route capable of guiding walking routes and railroad route routes. The present invention relates to a guidance system and a route guidance server.

  In response to a request from the user of the mobile terminal device, there is an optimum route search / guidance system that searches a route for moving from the current location to the destination by walking → railway vehicle → walking and provides the user with the mobile terminal device ( Patent Document 1). In this system, the optimal route search / guidance device that has received the current location information, destination information, and route guidance request transmitted from the mobile terminal device is the public transportation departure / arrival time database, public transportation departure / arrival place / fee database, and regional information. Search and judge the database, search for the optimum route and public transportation to be used, and provide it to the portable terminal device.

  By the way, when moving by walking → railway vehicle → walking in this way, the user may make a route search request to the destination after getting on the railcar. However, in a system in which a search is started from a walking route, such as the system described in Patent Document 1, the following problem occurs when a route search request is made while riding on a railway vehicle.

  That is, for example, when a user takes a train around Yamanote Line that departs Kanda Station at a certain time and makes a route search request immediately after departure, the current position of the user at the time of making the route search request is Kanda Station-Tokyo Station The system cannot recognize that the user is on the train even though it is on the railway line in between, so the system is on a road near the current position represented by the current position information transmitted from the mobile terminal device. Route search is performed using the map-matched position as the departure point. As a result, a route returning from the departure place to Kanda Station on foot is searched, and time data of a train having a departure time later than that of the train on board is provided.

  Therefore, a navigation system that addresses this problem has been proposed (Patent Document 2). In this navigation system, when a user of a mobile terminal device makes a route search request to the navigation server while getting on a railroad vehicle, the user inputs that the user is getting on the search condition input screen. In the navigation server, after specifying the boarding station, the vehicle being boarded is specified, and the route guidance is started from the actually boarding vehicle.

  Here, the boarding station is specified by any one of the following methods a, b, and c. “A: The record when the mobile terminal device passes the automatic ticket gate is acquired from the mobile terminal device to identify the boarding station.” If the record cannot be acquired, “b: GPS reception built in the mobile terminal device” Stations near the position represented by the current position information generated by the machine are listed and transmitted to the mobile terminal device to allow the user to select. ”If both a and b are impossible,“ c : Let the user enter the boarding station name. "

  After the boarding station is identified by the above method, the timetable database is accessed, the vehicles (routes and departure times) that the user is estimated to be on are listed, and transmitted to the mobile terminal device to the user. Based on the result, the vehicle on board is identified, and a route search is performed.

  However, in the navigation system described in Patent Document 2, it is necessary for the user to input that the user is on the board from the search condition input screen by any of the methods a, b, and c. In addition, when a record when passing through the automatic ticket gate cannot be obtained and there is no station near the current position, the user needs to input the boarding station name.

<Operation of route guidance system>
2 is a flowchart showing the operation of the route guidance system according to the embodiment of the present invention, FIG. 3 is a flowchart showing the contents of the route search preparation process in FIG. 2, and FIG. 4 is the contents of the route search process in FIG. It is a flowchart which shows.

  In FIG. 2, the operation flow of the mobile terminal device 50 starts when the route guidance application is activated by the user.

  First, the control unit 51 generates a connection request signal and transmits it to the route guidance server 10 via the communication unit 55 (step S1). The connection request signal includes the terminal device ID of the mobile terminal device 50 stored in the storage unit 56.

  In the route guidance server 10, the connection request signal is received by the communication unit 12 and sent to the control unit 11, whereby the flow on the route guidance server 10 side starts. In the route guidance server 10, it is determined whether or not the terminal device ID included in the connection request signal is registered in the storage unit 13. If registered, the route search is performed on the display unit 53 of the mobile terminal device 50. Route search condition input screen data for displaying the condition input screen is generated and transmitted to the mobile terminal device 50 (step S11). Although illustration is omitted, when the terminal device ID is not registered in the storage unit 13, the flow on the route guidance server 10 side is terminated or registration request screen data for prompting the user to register is transmitted.

  The mobile terminal device 50 receives the route search condition input screen data, and displays the route search condition input screen on the display unit 53 (step S2). Next, the mobile terminal device 50 sets the starting point, the destination, and the moving route of the route search condition (step S3). Here, the current position represented by the current position information (latitude information, longitude information, positioning time information) generated by the positioning unit 52 is set as the departure point, and the user inputs from the operation unit 54 as the destination. It is assumed that the destination is set and the “railway / walking route” selected by the user from the operation unit 54 is set as the travel route. Such setting information is stored in the RAM in the control unit 51.

  Next, the control unit 51 generates a route search request signal including each setting information and transmits it to the route guidance server 10 (step S4). In the route guidance server 10, the control unit 11 monitors the reception of the route search request signal in the communication unit 12, and when the communication unit 12 receives the route search request signal and sends it to the control unit 11 (step S12), the route Search preparation processing is executed (step S13).

  As shown in FIG. 3, in the route search preparation process, the route guidance server 10 first receives position information of the mobile terminal device 50 from the user information server 40 for a predetermined time (for example, 5 minutes) before the current time, that is, the mobile terminal device 50. The position information of the user is acquired (step S21). At this time, the route guidance server 10 sends a user information request signal including the terminal device ID of the mobile terminal device 50 to the user information server 40, and the user information server 40 receives the position information corresponding to the received terminal device ID as the user information DB 43. Is read from the route information and transmitted to the route guidance server 10. If the received terminal device ID is not registered in the user information DB 43, the flow on the route guidance server 10 side is terminated, or the process proceeds to step S24 described later.

  Next, the route guidance server 10 acquires the map data near the current position of the mobile terminal device 50, that is, the map data near the current position of the user of the mobile terminal device 50 from the map server 20 (step S22).

  Next, the route guidance server 10 uses the position information within a predetermined time from the current time of the mobile terminal device 50 acquired in step S21 and the map data near the current position of the mobile terminal device 50 acquired in step S22. It is determined whether or not the 50 travel routes are on the railway line, that is, whether or not the user of the mobile terminal device 50 is on the railcar (step S23).

  This determination is performed as follows. If the position represented by the position information within a predetermined time from the current time acquired in step S21 is moving at the speed of the railway vehicle on the railway line or along the railway line in the map data acquired in step S22, It is determined that the user of the terminal device 50 is on the railway vehicle. On the other hand, when it is not so, for example, when moving toward the station at a speed of walking or bicycle, it is determined that the train is not being boarded.

  As a result of the determination, when the vehicle is not on the railroad car (step S23: NO), the departure point set by the portable terminal device 50, that is, the current position of the portable terminal device 50 is set as the departure point of the route search (step S24). ).

  If the result of the determination is that the user is on the railway vehicle (step S23: YES), the route guidance server 10 acquires data representing the candidate vehicle that the user is estimated to be on from the timetable server 30 ( Step S25). That is, for example, the route name of the railway vehicle currently running near the current position of the mobile terminal device 50 and the data indicating the station name and departure time of the station that has just stopped are acquired. Further, the station where the user has boarded is estimated based on the location information of the mobile terminal device 50 before the present time, and the vehicle candidate that the user is estimated to be on board from the timetable server 30 based on the station information. (The name of the railway vehicle currently traveling near the current position of the mobile terminal device 50, the name of the station where the user is estimated to be on board, and the departure at the station where the user is estimated to be on board) Data representing time) may be acquired.

  Next, the route guidance server 10 creates a confirmation dialog for allowing the user of the mobile terminal device 50 to check the vehicle on board, and transmits the confirmation dialog to the mobile terminal device 50 (step S26).

  As shown in FIG. 2, in the mobile terminal device 50, after transmitting the route search request signal (step S4), the reception of the confirmation dialog is monitored (step S5), and if received (step S5: YES), It displays on the display part 53 (step S6).

  Here, the confirmation dialog is, for example, “Is the passenger riding the Keihin Tohoku Line from 15:26 Shimbashi?”. Since the vehicle is traveling simultaneously on a plurality of routes extending in parallel, when there are a plurality of vehicles that are estimated to be on the user's boarding, the list is displayed and the user is allowed to select. You can also.

  In the mobile terminal device 50, it is determined whether or not the user has input a confirmation response from the operation unit 54 with respect to the confirmation dialog (step S7). If the confirmation response is input (step S7: YES), the confirmation response is sent to the route guidance server. 10 (step S8).

  As shown in FIG. 3, after transmitting the confirmation dialog (step S26), the route guidance server 10 monitors the reception of the confirmation response (step S27), and if received (step S27: YES), the confirmation response The user identifies the vehicle on board based on this, and sets the stop station immediately before the current time on the route on which the vehicle is traveling as the departure place (step S28). In the case of the confirmation dialog exemplified above, Shimbashi Station on the Keihin Tohoku Line is set as the departure place.

  If the confirmation response is not received within the predetermined time (step S27: NO), the vehicle is selected on the basis of the predetermined reference from the vehicles to be confirmed in the confirmation dialog, and the current time on the route on which the vehicle is traveling The immediately preceding stop station is set as the departure place (step S29).

  That is, for example, when there is one vehicle to be confirmed in the confirmation dialog, the stop station immediately before the current time on the route on which the vehicle is traveling is set as the departure place. Further, when there are a plurality of vehicles to be confirmed in the confirmation dialog, one vehicle is selected in consideration of the destination, for example.

  When the starting point of the route search is set by executing step S24, S28 or S29, the route search preparation process is terminated and the process proceeds to the route search process (step S14).

  As shown in FIG. 4, in the route search process, the route guidance server 10 first determines whether or not the departure place is a station (step S31). If the result of the determination is that the departure point is a station (step S31: YES), the railway route route from that station to the nearest station of the destination and the walking route ahead is searched (step S32). The process ends. If the departure point is not a station (step S31: NO), the walking route to the nearest station of the departure point, the railway route route from that station to the nearest station of the destination, and the walking route ahead are searched. (Step S33), and the route search process is terminated.

  Returning to the description of FIG. Next, the route guidance server 10 transmits the route search results (route data, vehicle arrival / departure time data, map data) to the mobile terminal device 50 (step S15). When the mobile terminal device 50 transmits a confirmation response (step S8), does not receive a confirmation dialog within a predetermined time (step S5: NO), or does not input a confirmation response within the predetermined time (Step S7: NO), the reception of the route search result is awaited. When the route search result is transmitted from the route guidance server 10, it is received and displayed on the display unit 53 (Step S9).

As described above in detail, the route guidance system according to the embodiment of the present invention has the following features (1) to (2).
(1) When the route guidance server 10 receives a route search request starting from the current position from the mobile terminal device 50, the past position within a predetermined time from the current time of the mobile terminal device 50 stored in the user information DB 43 Based on the information and the position information of the railway line stored in the map DB 23, it is determined whether or not the portable terminal device 50 is moving on the railway line. When making a route search request while riding, there is no need to input that the train is on board.
(2) When it is determined that the mobile terminal device 50 is moving on the railway line, by referring to the timetable DB33, information representing a railway vehicle estimated to be on the user of the mobile terminal device 50 ( Route name, departure time of the stop station just before the current time, etc.) and a confirmation dialog is displayed on the portable terminal device 50, so the user of the portable terminal device 50 only needs to respond to the confirmation dialog, It becomes unnecessary.

  In the above embodiment, the configuration is such that the confirmation dialog and the confirmation response are exchanged between the route guidance server 10 and the mobile terminal device 50 even when there is one vehicle to be confirmed in the confirmation dialog. The exchange may be performed only when there are a plurality of vehicles to be confirmed in the confirmation dialog, and the exchange may be omitted if there is one vehicle to be confirmed in the confirmation dialog.
