[Navigation system processing]
Next, an example of the processing of the navigation system according to the first embodiment configured as described above will be described in detail with reference to FIGS. FIG. 2 is a flowchart illustrating an example of processing of the navigation system according to the first embodiment.

  As shown in FIG. 2, first, the route search request transmission unit 102b of the terminal device 100 receives a route search condition including a departure point, a destination, and a railroad use via the input unit 118 by the user. A route search request including the route search condition is transmitted to the navigation server 200 (step SA-1). Here, the departure place may be the current position of the user of the terminal device 100 based on the current position information acquired by the current position information acquisition unit 102a. The departure time may be the current time. In addition, the route search condition may include a transit point, a moving means other than railroad use, a departure time, a transit time, an arrival time, and / or a date.

  Then, the route search request receiving unit 202a of the navigation server 200 receives the route search request transmitted from the terminal device 100 (step SA-2).

  Then, the reference route search unit 202b of the navigation server 200 determines a reference route that is a guide route from the departure point to the destination that satisfies the route search condition included in the route search request received by the route search request reception unit 202a as a traffic. Based on the traffic information stored in the information database 206b, search is performed using the network information stored in the network information database 206a, and reference route information that is route information related to the reference route is generated (step SA-3). Here, when a route point is included in the route search condition, the reference route search unit 202b may search for a reference route that passes through the route point.

  Then, the reference route information transmission unit 202c of the navigation server 200 includes the map information related to the map including the reference route stored in the map information database 206c, the reference route information generated by the reference route search unit 202b, and the network information database 206a.

Here, the reference route information transmitting unit 202c may further transmit guide information (display guide information, voice guide information, etc.) output on the reference route, stored in the guide information database 206d.

  The reference route information receiving unit 102c of the terminal device 100 receives the map information, the reference route information, and the route network information transmitted from the navigation server 200, and receives the received map information, reference route information, and route. The network information is stored in the route guidance information file 106a (step SA-5). Here, when receiving the guide information from the navigation server 200, the reference route information receiving unit 102c may store the guide information in the route guide information file 106a.

  Then, the reference route information display unit 102d of the terminal device 100 superimposes the reference route information and the route network information stored in the route guidance information file 106a on the map information stored in the route guidance information file 106a. Is displayed on the display unit 114 (step SA-6). Here, the reference route information display unit 102d may further display the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a on the display unit 114 in a superimposed manner.

That is, the reference route information display unit 102d may not only output the reference route on the route map but also display it as character information.

  Then, the control unit 102 of the terminal device 100 receives part of the station information, the route information, or the map information included in the route network information displayed on the display unit 114 via the input unit 118 by the user. It is determined whether or not it has been selected (step SA-7). Here, the selection may be a range selection by clicking, tapping, dragging, or the like. Further, the station information may be selected by distinguishing between the boarding station, the getting-off station, or the transit station. That is, the control unit 102 determines whether or not a railway station or route is designated.

  And the selection information transmission part 102e of the terminal device 100 is determined that the part of station information, route information, or map information was selected by the control part 102 in step SA-7 (step SA-7: Yes), any one of the station information, the route information, or the map point information corresponding to a part of the map information is transmitted to the navigation server 200 (step SA-8).

  Then, the selection information receiving unit 202d of the navigation server 200 receives the selection information transmitted from the terminal device 100 (step SA-9).

  Then, the change destination setting unit 202e of the navigation server 200 sets a station, a route, or a point on the map (for example, a facility) based on the selection information received by the selection information receiving unit 202d as the change destination (step SA). -10). Here, the change destination setting unit 202e not only sets the route or point (station, facility, etc.) directly designated by the user of the terminal device 100 as the change destination, but also by the selection information receiving unit 202d. Candidates such as stations or routes may be set as the change destination from within the range around the point on the map based on the received selection information.

  The changed route search unit 202f of the navigation server 200 is set by the change destination setting unit 202e from the starting point to the destination that satisfies the route search condition included in the route search request received by the route search request receiving unit 202a. Based on the type of change destination, a change route that is a guide route using the change destination is searched using the network information stored in the network information database 206a based on the traffic information stored in the traffic information database 206b. Then, changed route information that is route information related to the changed route is generated (step SA-11). Here, when the change destination is a stop point, the change route search unit 202f may search for a change route that is a guide route using a route connected to the stop point. Further, when the change destination is a route, the changed route search unit 202f may search for a changed route that is a guide route using at least one section of the route. In addition, using the change destination means that the stop point that is the change destination is a public transport boarding point (for example, a boarding station), a getting-off point (for example, a getting-off station), or a transit point (for example, a transit station) Etc.), it may be used for public transportation that operates the route that is the change destination, and the point on the map that is the change destination is used as a transit point in the walking route It may be. The changed route search unit 202f is a remaining guide route connected to a part of the reference route using the change destination set by the change destination setting unit 202e from the departure point to the destination satisfying the route search condition. A certain remaining route may be searched, and a guide route connecting the part of the reference route and the remaining route may be acquired as a changed route. For example, the changed route search unit 202f searches for a remaining route that is a guide route that connects to a reference route at two connecting stations via a station set as a change destination between a departure point and a destination. Part of the reference route from the ground to the first connected station, the remaining route from the first connected station to the second connected station, and the reference from the second connected station to the destination You may acquire the guidance route which connected a part of route as a change route.

  In addition, when the station is set as the change destination, the changed route search unit 202f starts from the departure point and uses the route connected to the designated station to reach the destination. May be searched. In addition, when a route is set as a change destination, the changed route search unit 202f searches for a changed route that is a guide route that starts from the departure point and uses between stations of at least one section of the specified route. May be. In addition, the change route search unit 202f passes through the POI when the POI is set as the change destination and there is a moving means related to the POI (for example, the POI is an accommodation facility and the moving means is a shuttle bus of the accommodation facility) Then, a changed route that is a guide route using the moving means related to the POI may be searched. In this manner, the change route is searched based on the attribute type (point or route) to be selected depending on whether the station (so-called point) is designated or the route is designated. The changed route search unit 202f may re-search a part of the reference route. In addition, when a route point is included in the route search condition, the changed route search unit 202f may search for a changed route that passes through the route point. The changed route searching unit 202f not only searches for a changed route from the departure point to the destination, but also selects information from the terminal device 100 by the selection information receiving unit 202d during route guidance such as a reference route in the terminal device 100.
