For example, the user instructs the input device 203 to input the name, telephone number, or address of a landmark that is a destination as destination information.

  When the destination information is input from the input device 203, the arithmetic processing device 204 inputs the terminal location information from the location information acquisition device 202 (step S102). Arithmetic processing device 204 instructs wireless communication device 201 to transmit destination information and terminal location information. Then, the wireless communication device 201 transmits the destination information and the terminal location information to the search server 10 via the wireless base station and the communication network 50 according to the instruction of the arithmetic processing device 204 (step S103).

  The search server 10 searches for a route to the destination based on the destination information and terminal position information received by the communication device 102, and transmits the search information to the mobile terminal 20 via the communication network 50 and the wireless base station ( Step S104). In the present embodiment, the arithmetic processing unit 101 of the search server 10 uses, as search information, the location information of the boarding station, the location information of the getting-off station, the location information of the destination, the train search information, the departure location walking time, and the destination walking location.

  For example, the arithmetic processing unit 204 processes a map stored in advance by a storage device (not shown) of the mobile terminal 20 to generate a route map. For example, the arithmetic processing unit 204 adds a route from the current position to the boarding station to the map based on the position information from the position information acquisition unit 202 and the boarding station location information included in the search information. In addition, the arithmetic processing unit 204 adds a route from the getting-off station to the destination on the map based on the position information of the getting-off station and the destination included in the search information. Note that the arithmetic processing unit 204 may generate a route map by processing the map received from the search server 10.

  Moreover, the arithmetic processing unit 204 generates a route flowchart based on the train search information, the departure point walking time, and the destination walking time included in the search information.

  FIG. 3 is an explanatory diagram illustrating an example of a route map and a route flowchart displayed by the mobile terminal 20. As shown in FIG. 3, in the present embodiment, the mobile terminal 20 displays a route flowchart 302 superimposed on the route map 301 on a single screen. As shown in FIG. 3, the route map 301 includes a route from the current position 303 to the boarding station 304, a route from the boarding station 304 to the getting-off station 305, and a route from the getting-off station 305 to the destination 306.

  The user moves on foot to the boarding station while viewing the route map and route flowchart. When the arithmetic processing unit 204 determines that the user has arrived at the boarding station, the arithmetic processing unit 204 causes the display unit 205 to switch the display from the route map to the search platform diagram. For example, the arithmetic processing unit 204 determines whether or not the difference between the position information from the position information acquisition apparatus 202 and the position information of the boarding station included in the search information is equal to or less than a predetermined distance. If it is determined that the difference from the position information of the boarding station is equal to or less than the predetermined distance, the arithmetic processing unit 204 determines that the user has arrived at the boarding station, and displays the search platform diagram included in the search information on the display unit 205. Display.

  FIG. 4 is an explanatory diagram showing an example of a search platform diagram. As shown in FIG. 4, in the present embodiment, the mobile terminal 20 displays a route flowchart 302 on the search platform diagram 401 and displays it on a single screen.

In addition, the search platform diagram 401 includes a current position 403 of the mobile terminal 20. For example, the arithmetic processing unit 204 adds the current position 403 to the search platform diagram 401 based on the position information from the position information acquisition unit 202 and causes the display unit 205 to display the position.

  When the departure time has passed, the arithmetic processing unit 204 determines whether or not the user has boarded the designated train (step S106). For example, the arithmetic processing unit 204 determines whether or not the mobile terminal 20 has started moving along the route from the boarding station based on the position information from the position information acquisition unit 202. If it is determined that the movement has started, the arithmetic processing unit 204 determines that the user has boarded the designated train. Further, for example, the user may input from the input device 203 whether or not he / she can get on a specified train. In this case, the arithmetic processing unit 204 determines whether or not the user has boarded the designated train based on the input from the input unit 203.

  If it is determined that the designated train cannot be boarded, the arithmetic processing unit 204 returns to the process of step S102 again. That is, the portable terminal 20 transmits the destination information and the terminal position information to the search server 10 again, and requests the search server 20 to search for a route again.

  If it is determined that the specified train has been boarded, the arithmetic processing unit 204 causes the display unit 205 to switch the display from the search platform diagram to the search vehicle interior diagram. FIG. 5 is an explanatory diagram illustrating an example of a search vehicle interior diagram. As shown in FIG. 5, in the present embodiment, mobile terminal 20 displays route flowchart 302 on search vehicle interior diagram 501 in a single screen. As shown in FIG. 5, the search vehicle interior diagram 501 includes a standing position 502 in the vehicle where the distance to the exit at the getting-off station is the shortest. In addition, the search vehicle interior diagram 501 includes a current position 503 of the mobile terminal 20. For example, when the train stops at a station or the like, the arithmetic processing unit 204 adds the current position 503 to the search vehicle interior diagram 501 and displays it on the display unit 205 based on the position information from the position information acquisition unit 202.

  When the getting-off station approaches, the arithmetic processing unit 204 notifies the user that the getting-off station is approaching (step S107). For example, the arithmetic processing unit 204 determines whether or not the difference between the position information from the position information acquisition unit 202 and the position information of the getting-off station included in the search information is equal to or less than a predetermined distance. If the arithmetic processing unit 204 determines that the difference from the position information of the getting-off station is equal to or less than a predetermined distance, the arithmetic processing unit 204 outputs a sound or buzzer sound indicating that the getting-off station is approaching, to the sound output unit (not shown). ). In addition, for example, the arithmetic processing unit 204 uses a vibration function of the mobile terminal 20 to notify by vibration that the getting-off station is approaching.

  When the arrival time at the getting-off station has passed, the arithmetic processing unit 204 determines whether or not the user has got off at the getting-off station (step S108). For example, the arithmetic processing unit 204 determines whether or not the moving speed of the mobile terminal 20 is equal to or lower than a predetermined speed based on the position information from the position information acquiring unit 202. If it is determined that the speed is equal to or less than the predetermined speed, the arithmetic processing unit 204 determines that the user has been able to get off at the getting-off station. If it is determined that the speed is higher than the predetermined speed, the arithmetic processing unit 204 determines that it cannot get off at the getting-off station. Further, for example, the user may input from the input device 203 whether or not the user can get off at the getting-off station. In this case, the arithmetic processing unit 204 determines whether it is possible to get off at the getting-off station based on the input from the input device 203.

  If it is determined that the user cannot get off at the getting-off station, the arithmetic processing unit 204 returns to the process of step S102 again. That is, the portable terminal 20 transmits the destination information and the terminal position information to the search server 10 again, and requests the search server 20 to search for a route again.

  When it is determined that the user can get off at the getting-off station, the arithmetic processing unit 204 causes the display device 205 to switch the display from the searched vehicle interior map to the route map, and the route map illustrating the remaining walking route from the getting-off station to the destination. Is displayed (step S109). When the user arrives at the destination, the arithmetic processing unit 204 ends the navigation process (step S110).
