The layer stores the layer where the ticket gate is located in the station (layer in the building). The latitude and longitude store the latitude and longitude as the position information of the ticket gate. For the latitude and longitude, for example, the latitude and longitude of representative points of a plurality of ticket gates can be used.

  FIG. 4 is an example of a route network in a station. In FIG. 4, for convenience of illustration, the upper side of the paper is described as the north side. This routing network includes 5 nodes and 8 links. FIG. 4 shows the latitude / longitude of the ticket gate and the mark positions P1 to P4 of the traveling direction determination latitude / longitude included in the ticket gate entrance / exit information 144. Since the mark position P1 is a ticket gate of a station, it is also referred to as a "gate P1". In the example of FIG. 4, the north side of the node N3 is outside the station premises, the south side of the node N3 and the north side of the node N2 are outside the ticket gate, and the south side of the node N2 is inside the ticket gate.

  The node N1 is a branch point of the link outside the ticket gate. The node N2 is a node located at the position of the ticket gate P1, in other words, at the doorway in the ticket gate. The node N3 is a node located at the entrance to the station premises.

  The link L1 is a link connecting the node N1 and the ticket gate P1 (node N2). The link L2 is a link extending from the ticket gate P1 (node N2) toward the home toward the south side. The link L3 is a link connecting the node N1 and the node N3. The link L4 is a link that extends northward from the node N3 toward the outside of the station premises. The link L11 is a link extending from the node N1 to the east side of the station premises. The link L21 is a link extending from the node N1 to the west side of the station premises. The links L22 and L23 are links connected from the link L21.

  As described above, the mark position P1 is the position of the ticket gate of the station, in other words, an arbitrary point provided at the position of the entrance / exit inside the ticket gate. The mark positions P2 to P4 are arbitrary points respectively provided on the links L3, L11, L21 extending from the node N1 on the station grounds.

  Returning to FIG. 3, the ticket gate entrance / exit information 144 will be described with reference to FIG. The combination of each item of the direction flag, the guidance ID, the guidance content, and the traveling direction determination latitude / longitude is used to guide the user to the “gateway entrance / exit”. The direction flag has a symbol for identifying whether the guidance content associated with the direction flag is a word to be guided in the direction into the ticket gate or a word to be guided in the direction from the ticket gate. It is stored. In the example of the present embodiment, the direction flag “1” indicates the direction of entering the ticket gate, that is, the direction from the link L1 to the link L2 in FIG. 4, and the direction flag “2” indicates that the ticket is inside the ticket gate. This indicates the exit direction, that is, the direction from the link L2 to the link L1 in FIG.

  The guide ID stores an ID for identifying the guide content. The guidance contents store the contents to be guided to the user. Note that the ticket gate name is inserted in “◯” in FIG.

  The traveling direction determination latitude / longitude stores latitude and longitude as position information used to identify the traveling direction after passing through the entrance / exit of the ticket gate. The latitude / longitude of the mark position P2 in FIG. 4 is stored in the traveling direction determination latitude / longitude of the entry E3 in FIG. Similarly, the latitude / longitude of the landmark position P4 is stored in the traveling direction determination latitude / longitude of the entry E4, and the latitude / longitude of the landmark position P3 is stored in the traveling direction determination latitude / longitude of the entry E5. Note that FIG. 4 does not show the mark positions corresponding to the traveling direction determination latitude and longitude of the entries E1 and E2.

  For example, in the example of the entry E1 in FIG. 3, the "central ticket gate" whose ticket gate entrance ID is identified by "01" is located at the location specified by the station "1F" and the latitude and longitude "XX / YY". It is shown that. Furthermore, guidance for a route that goes in the direction “1 (In)” that enters the ticket gate and passes through the traveling direction determination latitude / longitude “XX / YY” is identified as “route name +” identified by the guidance ID “01”. "Number line + direction information". In the actual guidance process, the content of the track information 143 described in FIG. 2 is searched for and adopted for “route name + track + direction information”. On the other hand, in the example of the entry E3 of FIG. 3, the “central ticket gate” whose ticket gate entrance ID is identified by “01” is located at the place identified by the station “1F” and the latitude and longitude “XX / YY”. It is shown that. Furthermore, guidance for a route that goes in the direction “2 (Out)” that exits from the ticket gate and that passes through the traveling direction determination latitude / longitude “XX / YY” outputs “○” identified by the guidance ID “04”. "Go straight".

  As described above, the ticket gate entrance / exit information 144 stores in advance a plurality of guide contents corresponding to each advancing direction after passing through the entrance / exit of the ticket gate, in association with the direction flag and the traveling direction determination latitude / longitude.

  FIG. 5 is a diagram showing an example of the facility entrance / exit information 145. The facility entrance / exit information 145 is a table that stores information regarding “entrance / exit to station premises”. The facility entrance / exit ID stores an ID for identifying each entrance / exit of the station. The facility entrance / exit name stores a name for identifying each entrance / exit. The layer stores the layer where the doorway is located in the station (layer in the building). The latitude and longitude store the latitude and longitude as the position information of the doorway. Regarding the direction flag, the guidance ID, the guidance content, and the traveling direction determination latitude / longitude, the “gate” may be regarded as a “station site”, and may be considered in the same manner as the ticket gate information 144.

A-1-2. Route search device (server 20):
The server 20 of FIG. 1 includes a CPU 210, a communication unit 220, a ROM / RAM 230, and a storage unit 240, and each unit is connected to each other by a bus (not shown).

  The CPU 210 controls each unit of the server 20 by expanding the computer program stored in the ROM into the RAM and executing the computer program, and also functions as the search unit 212. The search unit 212 searches for a route from the starting point to the destination based on the request from the server 10. Specifically, the search unit 212 uses the network data stored in the route information DB 242 and the route information DB 243 to search for a route based on, for example, the well-known Dijkstra method. The search unit 212 transmits the information on the route thus obtained to the server 10.

  The storage unit 240 includes a hard disk, a flash memory, a memory card and the like. The storage unit 240 includes a map information DB 241, a route information DB 242, and a route information DB 243. The map information DB 241 is a database that stores data representing map images. The data representing the map image includes information necessary for displaying the map, such as topography, buildings, and road shapes. In the present embodiment, since the server 10 also holds similar data, the map information DB 241 of the server 20 can be omitted.

  The route information DB 242 is a database that stores railway network data and railway timetable information. The railroad network data includes nodes that represent station positions and links that represent railroad sections that connect the nodes. The railway network data is used by the search unit 212 to search for a railway route.

  The route information DB 243 is a database that stores road network data. The road network data includes nodes and links that connect the nodes. An average travel time (travel time) of the road represented by each link is associated with each link as a link cost for each transportation means (walking, car, bus, etc.). The road network data is used by the search unit 212 to search for a route on the road.

A-1-3. Client device (smartphone 30):
The smartphone 30 includes a CPU 310, a communication unit 320, a ROM / RAM 330, a storage unit 340, an input / output unit 350, and a current position acquisition unit 360, and each unit is mutually connected by a bus (not shown). ing.

  The CPU 310 controls each unit of the smartphone 30 by expanding the computer program stored in the ROM into the RAM and executing the computer program, and also functions as the guide unit 312. The guide unit 312 guides the user of the smartphone 30 (that is, the user of the server 10) of the route information and the information of the entrance / exit to the station site included in the route. Specifically, for example, the guide unit 312 executes the following steps a1 to a3.

(A1) The guide unit 312 acquires the designation of “departure place” and “destination” from the user via the input / output unit 350. The acquisition of the departure point may be omitted based on the current position acquired by the current position acquisition unit 360. The guide unit 312 may acquire other conditions for route search (for example, waypoints, types of public transportation desired to be used, display order, walking speed, etc.).
(A2) The guide unit 312 transmits a route search request including the acquired information to the server 10. After that, the server 10 executes the guidance control process described later.
(A3) The guidance unit 312 acquires guidance information such as display information from the server 10. The display information includes route information and information about the entrance / exit to / from the station site included in the route. The guide unit 312 causes the input / output unit 350 to display the display information. Note that the guide unit 312 may output, from the input / output unit 350, a voice based on voice data that is included in the guide information and represents the content of the display information. Further, the guidance unit 312 may store guidance information such as display information in the storage unit 340.

  The communication unit 320 controls communication with other devices such as the server 10 via a communication interface (not shown). The storage unit 340 includes a hard disk, a flash memory, a memory card, and the like. The input / output unit 350 is various interfaces used to input / output information between the smartphone 30 and the user. As the input / output unit 350, for example, a touch panel as an input unit, an operation button, a microphone, a touch panel as an output unit, a liquid crystal panel, a speaker, an LED (Light Emitting Diode) indicator, or the like can be adopted. The current position acquisition unit 360 receives radio waves transmitted from artificial satellites that form a GPS (Global Positioning System) and acquires the latitude and longitude indicating the current position of the smartphone 30.

A-2. Guidance control processing:
FIG. 6 is a flowchart showing the procedure of guidance control processing. The guidance control process is a process of causing the smartphone 30 to guide the route information from the departure point to the destination designated by the user and the information about the entrance / exit to the station site included in the route. The guidance control process is triggered by the acquisition of the route search request from the smartphone 30.

  In step S102, the guidance control unit 114 of the server 10 acquires the position information of the "departure place" and the position information of the "destination" included in the route search request.

In step S110, the guidance control unit 114 of the server 10 uses the station information DB 142 to search for a station closest to the departure place (hereinafter also referred to as “departure station”). In step S112, the guidance control unit 114 calculates the time required to move from the departure place to the departure station. For example, the guidance control unit 114 can calculate the required time using the following calculation formula. As the predetermined moving speed, for example, a general moving speed for walking can be adopted.
Time required = (straight line distance from the departure place to the departure station x predetermined coefficient) / predetermined movement speed

  In step S114, the guidance control unit 114 of the server 10 uses the station information DB 142 to search for a station closest to the destination (hereinafter, also referred to as “destination station”). In step S116, the guidance control unit 114 calculates the time required to move from the destination to the destination station. Details are the same as step S112.

  In step S118, the acquisition unit 112 of the server 10 causes the search unit 212 of the server 20 to search for the train route from the departure station to the destination station, and acquires the searched train route.

  In step S120, the guidance control unit 114 of the server 10 executes the entrance acquisition process (FIG. 7) for the departure station. Here, the walking path from the departure place to the departure station and the information on the entrance to the station site of the departure station can be obtained. Details of the entrance / exit acquisition process will be described later.

  In step S122, the guidance control unit 114 of the server 10 executes the entrance acquisition process (FIG. 7) for the target station. Here, the walking path from the destination station to the destination and the information on the entrance / exit to the station grounds of the destination station can be obtained.

  In step S130, the guidance control unit 114 of the server 10 causes the walking route from the departure point to the departure station obtained in step S120, the train route obtained in step S118, and the destination station to the destination obtained in step S122. The walking path to the ground is combined with the information to generate display information to be displayed on the smartphone 30. The display information can be in the XML (Extensible Markup Language) format or the HTML (HyperText Markup Language) format, for example.

  In step S132, the guidance control unit 114 of the server 10 transmits the generated display information to the smartphone 30, and ends the process. After that, as described above, the smartphone 30 performs the guidance process based on the guidance information such as the display information.

A-3. Doorway acquisition process:
FIG. 7 is a flowchart showing the procedure of the entrance / exit acquisition process. The entrance / exit acquisition process is a process of acquiring information on the entrance / exit to the station premises and information on the entrance / exit of the ticket gate. The entrance acquisition process is executed as a subroutine of the guidance control process (FIG. 6).

  FIG. 8 is a diagram for explaining the entrance / exit acquisition processing. FIG. 8 is the same routing network as the example of FIG. Hereinafter, with reference to FIG. 8, an entrance / exit acquisition process (FIG. 6: step S122) for the destination station will be described as an example.

  In step S204, the guidance control unit 114 of the server 10 determines whether or not there is number line information. Specifically, the guidance control unit 114 searches for the number line information 143, and there is number line information of the arrival platform of the exit station (that is, the destination station) in the train route acquired in step S118 of the guidance control process (FIG. 6). Or not.

  When there is no track information (step S204: NO), the guidance control unit 114 of the server 10 requests the server 20 to search for a walking route between the representative point of the destination station and the destination (step S240). After that, the guidance control unit 114 acquires the walking route from the server 20 and ends the process.

  If the numbered line information is present (step S204: YES), the guidance control unit 114 of the server 10 requests the server 20 to search for a walking route between the platform of the destination station and the destination (step S210). Here, the latitude / longitude of the track information 143 searched in step S204 is used as the position information of the platform of the target station. In FIG. 8, the walking route RT acquired in step S210 is indicated by a thick line.

In step S212, the guidance control unit 114 of the server 10 compares the walking route RT acquired in step S210 with the ticket gate entrance / exit information 144. Specifically, the guidance control unit 114 compares the following b1 and b2.
(B1) Latitude / longitude of the point on the walking route RT acquired in step S210 at which the type of the link is switched to “inside the ticket gate” or “outside the ticket gate” (b2) latitude / longitude of the ticket gate P1 stored in the ticket gate entrance / exit information 144

  In step S214, the guidance control unit 114 of the server 10 determines whether the switching point of the link type (inside / outside of the ticket gate) on the walking route RT corresponds to the entrance / exit of the ticket gate. Specifically, the guidance control unit 114 determines whether the latitude / longitude (b2) of the ticket gate P1 is located inside the predetermined range RA1 (FIG. 8: alternate long and short dash line) centered on the latitude / longitude (b1) of the switching point. To determine. In this way, by expanding the matching range by using the predetermined range RA1, the guidance control unit 114 allows the latitude and longitude of the switching point of the link type and the latitude and longitude stored in the ticket gate information 144. Even when a deviation within the range occurs (when the position information does not completely match), both can be regarded as the same. In addition, the guidance control unit 114 can easily acquire the position information of the switching point on the walking route RT by using the link information (link type) included in the route information DB 243.

  When the switching point of the link type does not correspond to the entrance / exit of the ticket gate (step S214: NO), the guidance control unit 114 of the server 10 shifts the processing to step S222.

When the switching point of the link type corresponds to the entrance / exit of the ticket gate (step S214: YES), the guidance control unit 114 of the server 10 determines the ticket via the walking route RT acquired in step S210 and the ticket entrance / exit information 144. The traveling direction in which the user should proceed after passing through the entrance / exit is calculated (step S216). Specifically, the guidance control unit 114 compares the following c1 and c2.
(C1) Latitude / longitude on the walking route RT (c2) Travel direction determination latitude / longitude stored in the ticket gate entrance / exit information 144

  In step S218, the guidance control unit 114 of the server 10 locates at the ticket gate where the walking route RT is located inside the predetermined range RA2 (FIG. 8: alternate long and two short dashes line) centered on the traveling direction determination latitude / longitude of the ticket gate information 144. The entry of the information 144 is specified, and the guidance content of the entry is acquired. For example, in the example of FIG. 8, since the route RT passes through the inside of the predetermined range RA2 of the mark position P2 (gate / gateway information 144: entry E3), the guidance control unit 114 guides the entry E3 of the ticket / gateway information 144. Acquire the content "Go out and go straight." In this way, by enlarging the matching range by using the predetermined range RA2, the guidance control unit 114 is within the allowable range for the traveling direction determination latitude and longitude stored in the ticket gate information 144 and the walking route RT. Even when a shift occurs (when the position information does not completely match), both can be regarded as the same. In addition, the guidance control unit 114 can easily acquire the position information of the switching point on the walking route RT by using the link information (link type) included in the route information DB 243.

  Through steps S212 to S218 described above, the guidance control unit 114 of the server 10 obtains information about the entrance / exit of the ticket gate (that is, each item stored in the ticket entrance / exit information 144) from the walking route RT and the ticket entrance / exit information 144. Can be obtained.

In step S222, the guidance control unit 114 of the server 10 compares the walking route RT acquired in step S210 with the facility entrance / exit information 145. Specifically, the guidance control unit 114 compares the following d1 and d2.
(D1) Latitude / longitude of the point where the type of link is switched to “indoor” or “outdoor” in the walking route RT acquired in step S210 (d2) Facility entrance / exit (to the station ground) stored in the facility entrance / exit information 145 Latitude / longitude of entrance / exit

  In step S224, the guidance control unit 114 of the server 10 determines whether or not the switching point of the link type (indoor / outdoor) on the walking route RT corresponds to the entrance / exit to the station premises. Details are the same as step S214.

  When the switching point of the link type does not correspond to the entrance to the station premises (step S224: NO), the guidance control unit 114 of the server 10 ends the process.

When the switching point of the link type corresponds to the entrance / exit to the station premises (step S224: YES), the guidance control unit 114 of the server 10 uses the walking route RT acquired in step S210 and the facility entrance / exit information 145, After passing through the entrance / exit to the station premises, the traveling direction in which the user should proceed is calculated (step S226). Specifically, the guidance control unit 114 compares the following e1 and e2.
(E1) Latitude / longitude on the walking route RT (e2) Travel direction determination latitude / longitude stored in the facility entrance / exit information 145

  In step S228, the guidance control unit 114 of the server 10 identifies the entry of the facility entrance / exit information 145 in which the walking route RT is located inside a predetermined range centered on the traveling direction determination latitude / longitude of the facility entrance / exit information 145, and Get the guidance content of the entry. Details are the same as step S218.

  Through steps S222 to S228 described above, the guidance control unit 114 of the server 10 uses the walking route RT and the facility entrance / exit information 145 to find information about the entrance / exit to the station premises (that is, each item stored in the facility entrance / exit information 145). ) Can be obtained.

  In the above description, the entrance acquisition process (FIG. 6: step S122) for the target station has been described as an example. However, regarding the entrance / exit acquisition processing for the departure station (FIG. 6: step S120), the “destination” is the “departure point”, the “destination station” is the “departure station”, and the “exit station” is the “boarding station”. , And can be implemented in the same way after replacing them.

As guidance information, information regarding a train is guided as in message M21 (FIG. 10). On the other hand, the progress directions identified in step S216 of the entrance acquisition process (FIG. 7) are “after exiting from inside the ticket gate”, “after exiting from within the station premises”, and “after entering into the station premises” In the case of a direction, as guidance information corresponding to each traveling direction, information indicating the traveling direction itself (straight, right, left) like messages M11 (FIG. 9), M12 (FIG. 9), and M22 (FIG. 10). Etc.)

  As described above, the network data (route information DB 242, route information DB 243) has information about the entrances and exits of facilities for using public transportation (facility entrance name, ticket gate name, facility entrance and progress after passing through the ticket gates. When the route information) is not included, the acquired route information (route information from the departure point to the destination) naturally does not include the entrance / exit information. Even in such a case, according to the server 10 (route guidance device) of the above-described embodiment, information about the entrance / exit stored in the ticket gate entrance / exit information 144 and the facility entrance / exit information 145 (exit entrance / exit information storage unit) (gate entrance / exit gate) Each item stored in the information 144 and the facility entrance / exit information 145) can be used to guide the entrance / exit information in addition to the acquired route information.

  Further, according to the server 10 (route guidance device) of the above-described embodiment, the guidance control unit 114 causes the switching point of the predetermined route information in the obtained route to correspond to the entrance / exit of the facility for using public transportation. Only in the case of doing (FIG. 7, steps S214, S224: YES), the information of the entrance and exit is guided (FIG. 7: steps S218, S228). As a result, only the information on the entrances and exits on the route is guided, and the usability and intelligibility for the user of the server 10 can be improved.

  Further, according to the server 10 (route guidance device) of the above-described embodiment, the guidance control unit 114 guides the information of the entrance and exit in a manner associated with the position of the entrance and exit in the facility for using public transportation. (FIGS. 9 and 10). As a result, it becomes easier for the user of the server 10 to know which doorway the information on the doorway that was guided relates to.

  Further, according to the server 10 (route guidance device) of the above embodiment, the guidance control unit 114 causes the guidance information (FIGS. 9 and 10: messages M11, M12, M21, M21, M21, M21, M21, M21, Since it is possible to guide M22 “straight ahead, right, left, etc.”, it is possible to improve usability and intelligibility for the user of the server 10. Specifically, the guidance control unit 114 guides information about public transportation when the traveling direction after passing through the entrance / exit is the traveling direction after entering the ticket gate (FIG. 10: message M21). That is, the user can automatically obtain information about public transportation that should be used after entering the ticket gate. On the other hand, the guidance control unit 114 indicates the traveling direction itself when the traveling direction after passing through the entrance / exit is the traveling direction after exiting from the ticket gate or the traveling direction after entering / exiting the site.

B. Modification:
In the above embodiment, part of the configuration realized by hardware may be replaced with software, and conversely, part of the configuration realized by software may be replaced with hardware. Good. In addition, the following modifications are possible.

・ Modification 1:
In the above embodiment, the configuration of the navigation system 1 including the server 10 (route guidance device) has been illustrated. However, the configuration of the navigation system 1 is merely an example, and any aspect can be adopted. For example, at least a part of the functions included in the server 20 (route search device) may be installed in the server 10, or the functions included in one server 20 may be realized by a plurality of servers. Good. Further, as the client device, various devices such as a personal computer, a dedicated navigation device, a game machine, and a wearable device can be adopted instead of the smartphone 30.

  For example, although the navigation system 1 exemplifies the case where the latitude / longitude coordinate system is used as the position information, another coordinate system (for example, an XY coordinate system) may be used as the position information.

-Modification 2:
In the above embodiment, the configuration of the server 20 (route search device) has been illustrated. However, the configuration of the server 20 in the above embodiment is merely an example, and any aspect can be adopted. For example, the server 20 can omit or change some of its constituent elements or add constituent elements. For example, each function described above may be realized by cooperation of a plurality of servers, and at least a part of each DB described above may be stored in another server or another internal / external storage device. . The configuration of each DB described above can also be changed arbitrarily, and addition / deletion / change of items, storage format of data, and the like can be performed. Here, the change of the data storage format includes the division / change of the table and the change of the relation.

-Modification 3:
In the above embodiment, the guidance control process (FIG. 6) and the entrance / exit acquisition process (FIG. 7) have been described with an example of the processing procedure. However, various changes can be made to these processing procedures, and the processing content in each step may be added / omit / changed, or the execution order of the steps may be changed.

  FIG. 11 is an example of a guide screen according to the entrance / exit acquisition processing of the modified example. The difference from the screen W1 shown in FIG. 9 is the contents of the guidance messages M11a and M12a. The guide message M11a of the modified example includes, as the information about the entrance / exit of the ticket gate, a word such as "1F central exit ticket gate" for guiding the hierarchy of the ticket entrance / exit and the name of the entrance / exit gate. The guidance message M12a includes a word for guiding the floor of the facility entrance and exit and the name of the facility entrance, such as "1F central exit" as information about the entrance / exit of the station premises. As described above, the guidance messages M11a and M12a of the modified example do not include the wording for guiding the traveling direction.

  In the entrance / exit acquisition processing of the modified example shown in FIG. 11, the processing of steps S216 and S226 described in FIG. 7 (processing for identifying the traveling direction after passing through the entrance / exit) is omitted. Further, in the configuration of the modified example, the direction flag, guidance ID, guidance content, traveling direction determination latitude and longitude of the ticket gate information 144 (FIG. 3), and the direction flag, guidance ID, guidance content of the facility gateway information 145 (FIG. 5). The traveling direction determination latitude and longitude may be omitted. Even in this case, the user of the server 10 can know the information about the entrance / exit of the ticket gate and the information about the entrance / exit to the station site in addition to the information about the route.

  For example, the guidance control unit 114 may omit either one of the information about the entrance / exit of the station premises and the information about the entrance / exit of the ticket gate. When omitting the station site guidance, the facility entrance / exit information 145 (FIG. 5) and steps S222 to S228 of the entrance / exit acquisition processing (FIG. 7) can be omitted. When omitting the ticket gate guidance, the ticket gate entrance / exit information 144 (FIG. 3) and steps S212 to S218 of the entrance / exit acquisition processing (FIG. 7) can be omitted.

  For example, the guidance control unit 114 may change the guidance mode of the guidance messages M11, M12, M21, M22 (FIGS. 9 and 10). For example, the display of the guidance message does not have to be linked to the entrance. In this case, for example, the area for displaying the content of the guidance message may be provided separately from the area for displaying the map image. Further, instead of / displaying the content of the guidance message, a voice representing the content of the guidance message may be output from the input / output unit 350 of the smartphone 30 to guide the user. . Further, the content of the guidance message may be arbitrary information (symbols, pictograms, icons, etc. different for each traveling direction) corresponding to the traveling direction, instead of the wording corresponding to the traveling direction. Further, the content of the guidance message M21 when entering the entrance of the ticket gate may be information for guiding the traveling direction instead of the information regarding public transportation, like the guidance messages M11, M12, and M22 in other cases.

  For example, the guidance control unit 114 includes, in steps S212 and S222 of the entrance acquisition process (FIG. 7), “others” included in the route information acquired from the server 20 instead of the position information of the switching point of the “link type”. It is also possible to carry out the comparison with the position information of the doorway by using the position information of the switching point of "information of". As other information, for example, the type of node, other attribute information of links or nodes, etc. can be used.

  For example, in step S214 of the entrance acquisition process (FIG. 7), the guidance control unit 114 determines that the type of link (inside the ticket gate) is inside the predetermined range centered on the latitude / longitude (b2) of the ticket gate P1. By determining whether or not the latitude / longitude (b1) of the switching point (outside / outside) is located, it may be determined whether or not the switching point corresponds to the entrance / exit of the ticket gate.

  For example, in steps S216 and S226 of the entrance acquisition process (FIG. 7), the guidance control unit 114 specifies the advancing direction after passing through the entrance and exit, regardless of the advancing direction determination latitude and longitude of the ticket gate entrance information 144 and the facility entrance information 145. You may. For example, the guidance control unit 114 can specify the traveling direction after passing through the entrance and exit by analyzing the shape of the walking route RT.

  For example, the guidance control unit 114 does not have to use the predetermined ranges RA1 and RA2 in steps S212, S222, S216, and S226 of the entrance acquisition process (FIG. 7).

  For example, if the guidance control unit 114 determines in step S204 of the entrance / exit acquisition process (FIG. 7) that there is no track information, the exit station (that is, the destination station) in the train route acquired in step S118 of the guidance control process (FIG. 6). ), It may be further determined whether there is ticket gate information of the arrival home. If there is ticket gate information, the guidance control unit 114 may request the server 20 for a walking route between the ticket gate of the destination station and the destination, and then transition the processing to step S222 (departure station, The same applies to the place of departure).

  For example, the guidance control unit 114 specifies the representative point of the station in step S240 of the entrance acquisition process (FIG. 7) and performs a walking route search, and then guides the ticket gates (steps S212 to S218) and guides the entrance and exit. (Steps S222 to S228) may be performed (the same applies to the departure station and the departure place).
