The map display service refers to a service provided by the information processing apparatus 100 that displays a map with an arbitrary latitude and longitude at an arbitrary scale for a user.

  Each configuration of the information processing apparatus 100 for realizing such a map display service will be described. As illustrated in FIG. 1, the information processing apparatus 100 includes an input unit 110, a control unit 120, a storage unit 130, a communication unit 140, and a display unit 150.

  The input unit 110 is configured to receive an operation from an administrator of the information processing apparatus 100, and can be realized by a keyboard, a mouse, a touch panel, or the like.

  The control unit 120 includes an arithmetic processing unit 121 such as a CPU or MPU, a memory 122 such as a RAM, and an image processing unit (not shown). The arithmetic processing unit 121 operates various functional units by executing a program recorded in the storage unit 130 based on various inputs. This program may be stored in a recording medium such as a CD-ROM, or distributed via the network 400 and installed in a computer. The memory 122 is for temporarily storing various types of data necessary for computation and the like during execution of processing in the server program and the program.

  The storage unit 130 is configured by a storage device such as a hard disk, and records various programs necessary for executing processing in the control unit 120, data necessary for executing the various programs, and the like. Although not shown in FIG. 1, for example, the storage unit 130 preferably has map information, road network data, and the like.

  Map information refers to information for drawing a map. For example, the map information includes a map image, latitude and longitude information, and the like. Road network data consists of road intersections, inflection points, end points, etc. as nodes, routes connecting each node as links, node data (node latitude and longitude), link data (link numbers), and all links The database includes link cost information data relating to cost information (distance and required time). Content data refers to information that is displayed superimposed on a map. For example, the content data includes event information, store information, facility information, traffic regulation information, icons, note information, and the like.

  In the present embodiment, the storage unit 130 further includes a timetable information DB 131. In the timetable information DB 131, for example, data in which an identifier of each station is associated with information on a train departure time for each route passing through each station. In the present embodiment, the timetable information DB 131 is described as a configuration provided in the storage unit 130, but is not limited thereto. For example, the timetable information DB 131 may not be provided in the storage unit 130 but may be provided in an external server.

  Further, as illustrated in FIG. 1, the arithmetic processing unit 121 includes a reception unit 1210, an extraction unit 1211, an acquisition unit 1212, a selection unit 1213, a display control unit 1214, and a route search unit 1215 as functional units. It is desirable to have.

The accepting unit 1210 accepts a map display request regarding the reference point from the terminal device 200 in which the map application is installed. For example, the positioning unit 260 of the terminal device 200 can transmit the measured latitude and longitude of the current position to the receiving unit 1210 as the latitude and longitude of the reference point. Further, for example, the user may operate the terminal device 200 to designate the latitude / longitude of the reference point as a reference point on the map to be displayed, and transmit it to the reception unit 1210. The receiving unit 1210 can determine a display range of a map to be displayed on the terminal device 200 based on the received latitude and longitude of the reference point.
In addition, the reception unit 1210 may receive designation of the latitude and longitude of the destination together with the reference point from the user.

  The extraction unit 1211 refers to the map information stored in the storage unit 130 and extracts stations that are within a predetermined range from the reference point. The predetermined range can be, for example, within a circumference having a radius that is a distance obtained by multiplying the user's moving speed by a predetermined time (for example, 10 minutes) around the reference point. For example, the predetermined range may be a range included in the display range of the map displayed on the terminal device 200. In this case, the extraction unit 1211 can determine a display range based on a scale for displaying a map and determine a predetermined range. The extraction unit 1211 determines the latitude and longitude of a predetermined range, and extracts a station having the latitude and longitude included in the latitude and longitude from the map information.

  The acquisition unit 1212 acquires the timetable information of the extracted station. The acquisition unit 1212 can acquire the timetable information corresponding to the extracted station with reference to the timetable information DB 131 stored in the storage unit 130. When the storage unit 130 does not include the timetable information DB 131, the acquisition unit 1212 may query the external server and acquire the timetable information.

  Furthermore, the acquisition unit 1212 may extract only the stations on the route that can reach the destination received by the receiving unit 1210 in the route guidance process described later. Further, for example, in the route guidance process, the acquisition unit 1212 may extract only stations related to routes that can reach any point on the route searched by the route search unit 1215 described later.

  The selection part 1213 selects the departure time displayed on a map from timetable information based on the present time. For example, the selection unit 1213 can acquire departure times from the timetable information in a predetermined number in order from the closest to the current time. The number of departure times to be selected by the selection unit 1213 may be set as a default value in the information processing apparatus 100, or may be specified in advance by the user.

  The display control unit 1214 performs control so that the departure time selected by the selection unit 1213 is displayed on the map. The display control unit 1214 may create a map in which the departure time is superimposed on the map information. Alternatively, the display control unit 1214 transmits the map information and the departure time information to the terminal device 200 to create a map on the terminal device 200 side. It may be displayed.

  The route searching unit 1215 searches for a route to the destination based on the set cost information when the receiving unit 1210 receives the designation of the destination. For example, the route search unit 1215 searches for a route from the departure point to the destination by referring to the search network data such as road network data according to the reference point and the latitude and longitude of the destination transmitted from the terminal device 200. . At this time, the optimum route can be searched by sequentially searching for a link from the departure node to the destination node, and following the link having the smallest link cost information as a guide route. As such a route search method, a known method such as a label determination method or a Dijkstra method can be used. The “optimum” route means that the cost information from the departure place to the destination is the smallest.

  Next, map display processing and route guidance processing of the information processing apparatus 100 configured as described above will be described.

(Map display processing)
A map display process flow of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  When the user operates the terminal device 200 to activate the map application, the user selects a point where the map is to be displayed as a reference point. This selection may be performed by inputting the latitude / longitude or address of the point where the map is to be displayed, or may be selected by the user from a large scale map. When the user selects a point where the map is to be displayed, the terminal device 200 transmits the latitude and longitude of the reference point to the reception unit 1210. Note that the terminal device 200 may transmit the latitude and longitude of the current position when the user starts the map application as the latitude and longitude of the reference point.

  The accepting unit 1210 accepts the latitude / longitude of the reference point transmitted from the terminal device 200 (S101). The receiving unit 1210 can also determine the map display range from the received latitude and longitude of the reference point and the display scale of the map displayed on the terminal device 200.

The extraction unit 1211 refers to the map information stored in the storage unit 130, and extracts stations within a predetermined range from the latitude and longitude received by the reception unit 1210 (S102). When no station is included in the predetermined range (S103: NO), the station is not extracted and the map is displayed.
On the other hand, when the station is included in the predetermined range (S103: YES), the process proceeds to S104. For example, it is assumed that three stations S01 to S03 are included in a predetermined range. In this case, the acquisition unit 1212 acquires each timetable information of the stations S01 to S03 from the timetable information DB 131 (S104).

  Next, the selection part 1213 selects the departure time displayed on a map from the timetable information which the acquisition part 1212 acquired (S105). Here, a case where the current time is 15:15 will be described as an example. The selection unit 1213 selects, for example, three departure times that are close to 15:15 from the timetable information in ascending order. The display control unit 1214 generates a map by superimposing the departure time selected by the selection unit 1213 on the map information included in the display range, and transmits the map to the terminal device 200 (S106).

  FIG. 3 is a diagram illustrating an example of the map generated by the display control unit 1214 at this time. In this example, it is assumed that the station S01 has two lines A and B, the station S02 and the station S03 have only the C line, and the station S02 is a terminal station. In addition, U1 of FIG. 3 has shown the reference | standard point.

  As shown in FIG. 3, the blowouts F1 to F3 are superimposed on the stations S01 to S03. In the balloons F1 to F3, three departure times close to 15:15, which is the current time, are displayed in the order of closeness. Since there are two lines A and B at the station S01, a total of twelve are displayed for each line in order of up and down departure times close to 15:15. Since the station S02 is the terminal station, three departure times are displayed in the order of the descending departure time of the C line close to 15:15. In addition, the station S03 displays a total of six departure times on the C line, three in order of close to 15:15.

  Thus, according to the information processing apparatus 100 according to the present embodiment, it is possible to automatically extract a predetermined range of stations from the reference point, and further superimpose the departure time of the train on the extracted station. Can be displayed. Thus, the user can select a nearby station on the map and examine which station is appropriate for the selected station without checking the timetable for each selected station.

(Route guidance processing)
Next, a flow of route guidance processing of the information processing apparatus 100 according to the present embodiment will be described using FIG. In addition, about the process of S101 and S103-106, since it is the same as that of the map display process mentioned above, description is omitted.

  When the reception unit 1210 receives designation of the destination from the user (S151: YES), the route search unit 1215 refers to the road network data to obtain the latitude and longitude from the reference point received by the reception unit 1210 to the destination. Based on this, a route is searched (S152). Next, the acquisition unit 1212 refers to the timetable information DB 131, extracts stations that are stations within a predetermined range from the reference point and that can reach the destination, and extracts the timetable information of the extracted stations. Obtain (S153). Accordingly, the selection unit 1213 can select the departure time of the station regarding the route that can reach the destination.

  As described above, according to the information processing apparatus 100 according to the present embodiment, when displaying a map, it is possible to automatically extract a station in a predetermined range from the reference point, and further to the departure time of the train to the extracted station. Information can be superimposed and displayed on a map. Furthermore, when the user designates a destination, the information processing apparatus 100 according to the present embodiment can select the departure time of the station regarding the route that can reach the destination and display it on the map. it can. Accordingly, the user can acquire the departure time of a train departing from an appropriate station without checking which station on the map is a station on a route that can reach the destination.

[Second Embodiment]
In the second and subsequent embodiments, description of matters common to the first embodiment is omitted, and only different points will be described. In particular, the same operation effect by the same configuration will not be sequentially described for each embodiment.

  FIG. 5 is a diagram illustrating a configuration diagram of the information processing apparatus 100 according to the present embodiment. As shown in FIG. 5, in the information processing apparatus 100 according to the present embodiment, in addition to the configuration described in the first embodiment, the arithmetic processing unit 121 further includes a calculation unit 1216.

  The calculation unit 1216 calculates the required time from the reference point to the station extracted by the acquisition unit 1212. For example, the calculation unit 1216 calculates the required time according to the moving means of the user. Specifically, when the user is walking, the required time can be calculated as 4 km / h, and when the user is moving by car, the required time can be calculated as 20 km / h.

  In this embodiment, in addition to the function described in the first embodiment, the selection unit 1213 adds the current time and the required time calculated by the calculation unit 1216 to determine the boarding time, and the boarding time Based on this, the departure time can be selected. Further, it is desirable that the selection unit 1213 further determines the boarding time based on the adjustment time. The adjustment time refers to, for example, the time required to move to the home after the user arrives at the station or the time required to purchase a ticket. In this case, the selection part 1213 determines boarding possible time based on the time which added current time, required time, and adjustment time. As the adjustment time, an administrator of the information processing apparatus 100 may set an arbitrary time in advance, or the user may freely set an arbitrary time. Also, the adjustment time can be a different value for each station. In this case, it is desirable that the storage unit 130 stores the station and the adjustment time information in association with each other.

  A flow of map display processing of the information processing apparatus 100 according to the present embodiment configured as described above will be described with reference to FIG. In addition, since the process of S101-S106 is the same as that of 1st Embodiment, it omits description. In the example of FIG. 6, it is assumed that the current time is 15:15, and that three stations S01 to 03 are included within a predetermined range from the reference point. Furthermore, in this example, the adjustment time is assumed to be 5 minutes.

  In S104, when the timetable information of the station extracted by the extraction unit 1211 is acquired, the calculation unit 1216 calculates the required time from the reference point to each station (S201). For example, an example will be described in which the calculation unit 1216 calculates that the required time from the reference point to the station S01 is 30 minutes, the required time to the station S02 is 15 minutes, and the required time to the station S03 is 5 minutes. To do.

  The selection unit 1213 determines a boarding time based on the current time, the calculated required time, and the adjustment time (S202), and selects a departure time to be displayed. First, the selection unit 1213 determines the boarding time at each of the stations S01 to S03 in order to select a departure time to be displayed in association with each station.

  Since the required time to the station S01 is 30 minutes, the selection unit 1213 adds the required time of 30 minutes and the adjustment time of 5 minutes to the current time of 15:15, and sets the available ride time to 15:00. Decide after 50 minutes. Similarly, since the required time to the station S02 is 15 minutes, the selecting unit 1213 adds the required time of 15 minutes and the adjustment time of 5 minutes to the current time of 15:15, and can get on the train. Is determined after 15:35. Furthermore, since the required time to the station S03 is 5 minutes, the selection unit 1213 adds the required time of 5 minutes and the adjustment time of 5 minutes to the current time of 15:15 to obtain the available ride time. It is determined after 15:25. The selection unit 1213 refers to the timetable information acquired by the acquisition unit 1212, and selects three departure times that are close to the determined boarding time at each station in order from the closest.

  FIG. 7 is a diagram illustrating an example of map information generated by the display control unit 1214 in S106.

  In the blowout F1, as the departure time of the station S01, three departure times are displayed for each of the A line and the B line in order of 15:50 or later and closer to 15:50. Also, in the blowout F2, as the departure time of the station S02, three departure times are displayed for the C line in the order from 15:35 onwards and closer to 15:35. Furthermore, in the blowing F3, as the departure time of the station S03, three departure times are displayed for the C line in the order from 15:25 onward and closer to 15:25.

Thus, the information processing apparatus 100 according to the present embodiment can display the departure time on the map based on the required time to the station.
Other configurations and functions are the same as those in the first embodiment.

[Third Embodiment]

In the third embodiment, the storage unit 130 further includes a display off DB 132, and the arithmetic processing unit 121 includes a restriction unit 1217.

  In the display-off DB 132, information on routes that do not display the departure time on the map for each user (hereinafter, routes that do not display the departure time are also referred to as “display-off routes”) is registered.

  The restriction unit 1217 receives designation of a display off route from the user. The user can designate a route that is not usually used or a route that goes out of the living area as a display-off route. The restriction unit 1217 registers the received display-off route in association with the user in the display-off DB 132. The restriction unit 1217 may automatically select the display off route based on, for example, the user's action history, the location where the user used the Osaifu-Keitai function of the terminal device 200, and the user's daily area information. The daily zone information refers to information related to the user's life range. For example, a certain range from a reference point such as a user's home or work may be registered as a daily area. The daily zone information may be stored in advance in the storage unit 130, or the daily zone information held in the external server may be acquired by the restriction unit 1217 via the network 400.

In this embodiment, when extracting a station within the display range from the reference point, the extraction unit 1211 refers to the display-off DB 132 and excludes a station related to a route registered as a display-off route from the extraction target.
As a result, it is possible to suppress the display of the departure time of the station unnecessary for the user.
