[Processing of navigation server 200 (server-driven type)]
Next, an example of processing of the navigation server 200 in the second embodiment configured as described above will be described in detail below with reference to FIG.

  As illustrated in FIG. 11, first, the control unit 102 of the terminal device 100 transmits a route search condition including at least a departure place and a destination input by the user via the input unit 116 to the navigation server 200 ( Step SB-1). Here, the departure location may be the current location of the user of the terminal device 100 based on the location information signal received from the location transmission device 500 by the location acquisition unit 112. For example, the control unit 102 acquires the position information calculated from the position information signal received from the position transmission device 500 by the position acquisition unit 112 as the current position information of the user of the terminal device 100, and the terminal based on the current position information The current position of the user of the device 100 may be set as the departure place. Further, the control unit 102 may transmit the position information signal received from the position transmission device 500 by the position acquisition unit 112 to the navigation server 200. The route search condition may further include a waypoint. Further, the route search condition may further include a corresponding state of the moving means that is barrier-free.

  Then, the route search condition receiving unit 202a of the navigation server 200 receives a route search condition including at least a departure place and a destination transmitted from the terminal device 100 (step SB-2). Here, when the location information signal is received from the terminal device 100, the route search condition receiving unit 202a acquires the location information calculated from the location information signal as the current location information of the user of the terminal device 100, and the current location The current position of the user of the terminal device 100 based on the information may be set as the starting point of the route search condition.

  Then, the route searching unit 202b of the navigation server 200 selects a plurality or a single guide route from the starting point to the destination satisfying the route searching condition including at least the starting point and the destination received by the route searching condition receiving unit 202a. The search is performed using the network data stored in the network database 206a, and guide route data is generated (step SB-3). Here, when a route point is further included in the route search condition, the route search unit 202b may search for a guide route that passes through the route point.

  And the movement means extraction part 202c of the navigation server 200 determines whether the station is included in the guidance route searched by the route search part 202b (step SB-4).

  And when the movement means extraction part 202c of the navigation server 200 determines with the station being included in the guidance route searched by the route search part 202b in step SB-4 (step SB-4: Yes), The moving means data of the station stored in the moving means database 206b is extracted (step SB-5). Here, when the moving means extraction unit 202c determines that a station is included in the guidance route searched by the route search unit 202b in Step SB-4 (Step SB-4: Yes), the route search condition. The moving means data of the station stored in the moving means database 206b corresponding to the barrier-free information stored in the moving means database 206b that satisfies the barrier-free correspondence state specified in (2) may be extracted.

  The guidance display screen generation unit 202e of the navigation server 200 displays based on route guidance information including at least the guidance route data generated by the route search unit 202b and the movement means data extracted by the movement means extraction unit 202c. A screen is generated (step SB-6). When the guide display screen generation unit 202e determines in step SB-4 that the moving means extraction unit 202c does not include a station in the guide route (step SB-4: No), the route search unit 202b. A display screen based on the route guidance information including at least the guidance route data generated by the above is generated. Here, the guidance display screen generation unit 202e may generate a display screen composed of the guidance route data generated by the route search unit 202b and the movement means data extracted by the movement means extraction unit 202c. Further, the guidance display screen generation unit 202e may generate a display screen that displays the moving means based on the moving means data extracted by the moving means extraction unit 202c in a list format. In addition, the guidance display screen generation unit 202e displays a moving unit based on the moving unit data extracted by the moving unit extraction unit 202c in the order of guidance of the guidance route based on the guidance route data generated by the route search unit 202b. May be generated. The guidance display screen generation unit 202e displays a display screen of turn-by-turn display guidance data stored in the guidance database 206d associated with the moving unit based on the moving unit data extracted by the moving unit extraction unit 202c. May be generated. Further, the guidance display screen generation unit 202e may generate a display screen based on the route guidance information and the current position information of the user of the terminal device 100. Further, the guidance display screen generation unit 202e acquires the guidance route data generated by the route search unit 202b and / or the position of the terminal device 100 on the map data of the map including the guidance route stored in the map database 206c. The display screen may be generated by superimposing the current position information of the user of the terminal device 100 based on the position information signal periodically received from the position transmission device 500 by the unit 112. Here, the guidance display screen generation unit 202e receives the position information signal from the terminal device 100, calculates the position information from the position information signal, and acquires the position information as the current position information of the user of the terminal device 100. By doing so, a display screen may be generated. The guidance display screen generation unit 202e may generate a display screen based on display guidance data other than the TBT stored in the guidance database 206d.

  Then, the guidance display control unit 202f of the navigation server 200 transmits the display screen generated by the guidance display screen generation unit 202e to the terminal device 100, thereby causing the display unit 114 of the terminal device 100 to display the display screen. (Step SB-7). Here, for example, when the guidance display control unit 202f receives a route guidance start request or the like input by the user via the input unit 116 of the terminal device 100, the map generated by the guidance display screen generation unit 202e is used. On the map data of the map including the guide route stored in the database 206c, the guide route data generated by the route search unit 202b and / or the current location information of the user of the terminal device 100 acquired periodically is stored. The display screen may be displayed on the display unit 114 of the terminal device 100 by transmitting the superimposed display screen to the terminal device 100. For example, when the guidance display control unit 202f receives a voice navigation start request or the like input by the user via the input unit 116, the guidance point such as a branch point on the guidance route stored in the guidance database 206d. By transmitting the voice guidance data associated with the traveling direction or the like to the terminal device 100, the voice guidance data may be output via the voice output unit 118 of the terminal device 100. The route guidance display control and voice output control execution processing by the guidance display control unit 202f is performed until the terminal device 100 reaches the destination, waypoint, or guide point after the start of route guidance or voice navigation. May be continued, and / or repeated.
