  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of a moving route search system according to an embodiment of the present invention. The movement route search system 10 is an information processing system that searches for a movement route in accordance with a request from a user terminal such as the mobile terminal 20, and is configured using one or a plurality of information processing devices. As shown in FIG. 1, the travel route search system 10 includes a communication unit 30, a map information output unit 32, a facility search unit 34, a destination reception unit 36, a departure point candidate output unit 38, a departure point reception unit 40, a moving means. A specifying unit 42 and a movement route searching unit 44 are included. Each unit constituting the movement route search system 10 can be realized by using a storage area such as a memory or a storage device, or by executing a program stored in the memory by a processor. Details of each part of the movement route search system 10 will be described later.

  The mobile terminal 20 is a user terminal that uses the movement route search system 10, and is, for example, a mobile phone terminal or a mobile information terminal. Note that a non-portable information processing apparatus such as a personal computer may be used as the user terminal. As shown in FIG. 1, the mobile terminal 20 includes a communication unit 50, a position information acquisition unit 52, a control unit 54, a display unit 56, and an operation unit 58. Each unit constituting the mobile terminal 20 can be realized by using a storage area such as a memory or a storage device, or by executing a program stored in the memory by a processor.

  Before describing the details of the movement route search system 10, each unit of the mobile terminal 20 will be described. The communication unit 50 executes communication with the movement route search system 10 and the like via, for example, a cellular phone packet communication network. The movement information acquisition unit 52 acquires position information indicating the current position of the mobile terminal 20 through communication with a GPS (Global Positioning System) satellite or a mobile phone base station, for example. The control unit 54 controls various processes in the mobile terminal 20 such as a route search using the movement route search system 10. The display unit 56 displays various information such as map information, facility information, and route information on a display device such as a display. The operation unit 58 includes, for example, input keys, a touch panel, and the like, and accepts user operations on the mobile terminal 20.

  Each part of the movement route search system 10 will be described. The communication unit 30 performs communication with the mobile terminal 20 and other information processing systems via a network such as the Internet.

  The map information output unit 32 refers to a map information database (DB) 70 in response to a request from the mobile terminal 20 and outputs map information for displaying a map on the mobile terminal 20. For example, the map information output unit 32 can output map information for displaying a map near the current position of the mobile terminal 20 based on the position information received from the mobile terminal 20. Moreover, the map information output part 32 can output the map information for displaying the map relevant to the route information and facility information mentioned later. The map information DB 70 may be inside or outside the movement route search system 10.

  The facility search unit 34 refers to a facility information database (DB) 72 in response to a facility search request from the mobile terminal 20, acquires facility information regarding facilities that match the search conditions, and outputs the acquired facility information to the mobile terminal 20. The facility search request includes, for example, a name, genre, place name, station name, latitude / longitude, and the like. The facility information stored in the facility information DB 72 includes facility ID and name, facility attributes, genre, latitude / longitude, contact information, related images, charges, user reviews, and the like. The facility information DB 72 may be inside the movement route search system 10 or may be outside. Alternatively, the facility search unit 34 may transmit a facility information search request to an external server to execute a facility information search on the external server and return the search result to the facility search unit 34. Good.

  2 and 3 are diagrams illustrating an example of a screen on the mobile terminal 20 when a facility is searched for by a keyword. As shown in FIG. 2, it is assumed that the user inputs a keyword related to a facility to be searched and presses the execution button. The control unit 54 of the portable terminal 20 generates a facility search request for performing a search using the keyword, and transmits the facility search request to the movement route search system 10 via the communication unit 50. In response to this facility search request, the facility search unit 34 of the movement route search system 10 searches the facility information DB 72 for a related facility, and transmits the facility information of the related facility to the portable terminal 20. For example, as illustrated in FIG. 3, the control unit 54 of the mobile terminal 20 can display a list of facilities based on the facility information transmitted from the movement route search system 10. The map information output unit 32 of the movement route search system 10 may transmit map information for displaying a map related to the facility information to the mobile terminal 20. In this case, the control unit 54 of the mobile terminal 20 can also display an icon indicating the location of the facility on the map, for example. In addition, although the example which searches a facility using a keyword was shown here, the search method in the facility search part 34 is not restricted to this. For example, the facility search unit 34 can perform a search by an arbitrary method such as a search specifying a genre, a search for facilities within a predetermined distance from the current position, or a search specifying an area.

  Returning to FIG. 1, the destination receiving unit 36 receives destination information corresponding to the destination in the route search from the mobile terminal 20. The destination information may be information that can identify the destination, and may include, for example, the name and ID of a facility that is the destination, a telephone number, latitude / longitude, and the like. For example, when a certain facility is selected on the screen on which the list of facilities shown in FIG. 3 is displayed, the control unit 54 of the mobile terminal 20 displays an icon indicating the location of the facility on the map as shown in FIG. It is possible to display. Then, when it is selected that this facility is set as the destination, the control unit 54 of the portable terminal 20 generates destination information with the facility as the destination and transmits it to the travel route search system 10. Also good. It should be noted that any method can be used for setting the destination, such as setting an arbitrary point on the map as a destination, not from the search result.

  Returning to FIG. 1, the departure point candidate output unit 38 outputs departure point candidate information corresponding to a plurality of departure point candidates for the destination. Here, the departure point candidates are, for example, the nearest station at the destination, the nearest interchange (IC) on the motorway, the current location, and the home. The departure place candidate information is information for selecting one departure place from such departure place candidates. For example, the departure point candidate output unit 38 can output departure point candidate information for displaying the screen shown in FIG. On the screen shown in FIG. 5, it is possible to select the nearest station, nearest IC, current location, or home.

  The departure point candidate output unit 38 refers to the facility information DB 72 to search for the nearest station or nearest IC of the destination, thereby including the name of the nearest station or nearest IC in the departure point candidate information. It is good as well. In this case, on the screen shown in FIG. 5, it is also possible to display the name of the nearest station or the nearest IC. It is also possible to use the current station or the nearest station or nearest IC as the departure point candidate, not just the nearest station or nearest IC of the destination. Furthermore, the departure point candidate output unit 38 may output departure point candidate information corresponding to the destination with reference to the facility information DB 72. For example, when a station or IC exists within a predetermined range from the destination, departure point candidate information for displaying the nearest station or the nearest IC as a departure point candidate may be output.

  Returning to FIG. 1, the departure place receiving unit 40 receives departure place information corresponding to the departure place selected from the departure place candidates from the mobile terminal 20. For example, when one departure place is selected on the screen shown in FIG. 5, the control unit 54 of the portable terminal 20 generates departure place information corresponding to the selected departure place and transmits it to the movement route search system 10. be able to. Here, the departure point information may be, for example, information indicating the type of the selected departure point, or may be information that can identify the facility of the selected departure point. The user can also set an arbitrary point as a departure place other than those previously listed as candidates such as the nearest station and the nearest IC. In this case, for example, by selecting “Search” on the screen shown in FIG. 5, it is possible to search for the facility that is the departure place as in the examples of FIGS. 2 to 4. It is also possible to set an arbitrary point on the map as the departure point.

  Returning to FIG. 1, the moving means specifying unit 42 specifies moving means from the departure place to the destination based on the received departure place information. For example, when “Nearest IC” is selected on the screen shown in FIG. 5, the moving means assumed by the user is likely to be a car. Therefore, in this case, the moving means specifying unit 42 specifies the moving means as a car. On the other hand, for example, when “nearest station” is selected on the screen shown in FIG. 5, it is highly likely that the moving means assumed by the user is not a car. Therefore, in this case, the moving means specifying unit 42 specifies the moving means as walking, for example. Note that a moving means other than walking may be specified according to the distance between the nearest station and the destination. For example, when the distance between the nearest station and the destination is a predetermined distance or more, a bus or taxi can be added to the moving means. In addition, when the present location, home, or any other point is set as the departure place, it is possible to use a moving means preset by the user, or the user selects the moving means when selecting the departure place. Is also possible. In addition, for example, the moving means specifying unit 42 can acquire the attribute of the facility selected as the departure place from the facility information DB 72 and specify the moving means based on the attribute. For example, when the attribute of the facility selected as the departure place is “Michi no Eki”, the moving means specifying unit 42 may specify the moving means as a car.

  Returning to FIG. 1, the movement route search unit 44 refers to the route information database (DB) 74 in response to a route search request from the mobile terminal 20, and finds the movement route by the specified moving means from the departure point to the destination. Search is performed, and route information for displaying the travel route on a map is output to the mobile terminal 20. The route information DB 74 may be inside or outside the movement route search system 10. In addition, by transmitting a travel route search request from the travel route search unit 44 to an external server, the travel route search is executed by the external server, and the search result is returned to the travel route search unit 44. It is good.

  For example, when the specified moving means is walking, the moving route searching unit 44 refers to the route information DB 74, searches for a moving route by walking from the departure point to the destination, and obtains route information indicating the moving route. Output to the mobile terminal 20.

  When the specified moving means is a car, the moving route search unit 44 can refer to the facility information DB 72 to determine whether the destination is a facility in an underground shopping center. When the destination is an underground shopping center facility, a parking lot near the destination is not shown as shown in FIG. 7, but instead of simply searching for a moving route from the departure place to the destination as shown in FIG. It is possible to search for a movement route that passes through.

  For example, the travel route search unit 44 refers to the facility information DB 72, selects a parking lot within a predetermined distance from the destination, and travels by car from the departure location to the parking lot, and from the parking lot to the destination. It is possible to search for a moving route by foot. FIG. 8 shows an example in which a moving route passing through a parking lot is displayed on a map. In FIG. 8, the solid line represents the travel route by car, and the broken line represents the travel route by foot. As shown in FIG. 8, the walking route is via the entrance to the underground mall, and a map of the underground mall is displayed instead of the ground between the underground mall entrance and the destination facility.

  In FIG. 8, a map of the underground shopping area is displayed from the underground shopping area entrance to the destination facility, but a map of the ground may also be displayed in this section. In this case, the ground route and the underground route can be displayed in different display modes, for example, the ground route and the underground route are displayed in different colors. Further, even when only the map on the ground is displayed, it is possible to display a balloon or an icon so that it can be seen that it is an underground mall entrance as shown in FIG. For example, an icon for switching between a map on the ground and a map of the underground shopping street may be displayed, and the display of the map may be changed in accordance with the operation of the icon. In addition, for example, when it is detected that a user has entered an underground mall by communication with a base station installed in the underground mall, the map may be automatically switched to the map of the underground mall.

  FIG. 9 is a diagram for explaining an example of a criterion for selecting a parking lot near the destination. FIG. 9 shows a rectangle 80 having a starting point and a destination as vertices on a diagonal line, and a circle 82 having a radius of a predetermined distance around the destination. For example, if there is a parking lot in a region 84 where the rectangle 80 and the circle 82 overlap, the movement route search unit 44 can select this parking lot as a parking lot used in the movement route. In the parking lot in the area 84, the distance from the departure place to the parking lot is shorter than the distance from the departure place to the destination. When there is no parking lot in the area 84, for example, if there is a parking lot in the area 86 other than the area 84 in the circle 82, the movement route search unit 44 uses this parking lot as a parking lot used in the movement route. You can choose. In addition, when there is no parking lot in the circle 82, the moving route search unit 44 searches for a moving route by a car between the departure point and the destination, for example, and a parking lot within a predetermined distance from the route. Can be selected. Furthermore, when the distance from the parking lot selected outside the circle 82 to the destination is a predetermined distance or more, the movement route search unit 44 searches for a movement route including a bus or a taxi from the parking lot to the underground street entrance. It is good as well.

  In FIG. 9, when there are a plurality of parking lots along the area 84, the area 86, and the moving route by car, for example, the distance from the departure point and the destination, the parking fee, the congestion degree, and the progress of the car. A parking lot may be selected based on a predetermined criterion such as a positional relationship with a direction. Also, by outputting to the mobile terminal 20 parking lot candidate information corresponding to a plurality of parking lots within a predetermined distance from the destination, for example, as shown in FIG. It is good also as a parking lot being selected by. And the movement path | route search part 44 is good also as accepting the parking lot information regarding the parking lot selected by the user from the portable terminal 20, and searching the movement path | route via this parking lot. In addition, although the example which displays the information regarding a several parking lot on a map was shown in FIG. 10, the display form for selecting a parking lot is arbitrary, such as the information regarding a some parking lot being displayed on a list | wrist It is. Moreover, the selection criteria of the parking lot demonstrated with reference to FIG. 9 are examples, and arbitrary selection criteria can be employ | adopted.

  FIG. 11 is a flowchart showing an example of the operation of the movement route search system 10. First, the destination receiving unit 36 receives destination information corresponding to the destination from the mobile terminal 20 (S1101). The departure point candidate output unit 38 outputs departure point candidate information for selecting a departure point as illustrated in FIG. 5 (S1102). And the departure place reception part 40 receives the departure place information according to the departure place selected from several departure place candidates from the portable terminal 20 (S1103).

  When the departure place information is accepted, the moving means specifying unit 42 determines whether the departure place is an IC (S1104). When the departure place is not an IC (S1104: N), the moving means specifying unit 42 specifies that the moving means is walking (S1105). Then, the movement route search unit 44 searches for a movement route by walking from the departure point to the destination (S1106).

  When the departure place is an IC (S1104: Y), the moving means specifying unit 42 specifies that the moving means is a car (S1107). Then, the travel route search unit 44 determines whether the destination is an underground shopping center facility (S1108). When the destination is not an underground shopping center facility (S1108: N), the travel route search unit 44 searches for a travel route by car from the departure point to the destination (S1109). When the destination is an underground shopping center facility (S1108: Y), the travel route search unit 44 selects a parking lot within a predetermined distance from the destination (S1110), and a travel route by car from the departure location to the parking lot. And a walking route from the parking lot to the destination is searched (S1111).

  Finally, the travel route search unit 44 outputs route information for displaying the travel route search result on the map to the mobile terminal 20 (S1112).

  The travel route search system 10 of this embodiment has been described above. According to this embodiment, a moving means can be automatically specified according to a departure place selected from a plurality of departure place candidates. Thereby, it is not necessary to explicitly specify the moving means by the user operation, and the operation load on the user can be reduced in the route search system corresponding to the plurality of moving means. As a specific example, when the facility attribute of the departure place is IC, the movement route by the car from the departure place to the destination is presented to the user by automatically specifying that the moving means is a car. It becomes possible to do.

  Further, according to the present embodiment, when the moving means is specified as a car, it is possible to automatically search for a moving route via a parking lot if the destination is an underground mall. When the destination is an underground shopping center facility, there are few cases where it is possible to move to a position indicated by the latitude and longitude of the facility by car. Therefore, it is possible to improve convenience by presenting the movement route by car from the departure point to the parking lot near the destination and the walking route from the parking lot to the destination via the underground shopping street entrance Become.

  Note that this embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  For example, in this embodiment, when the destination is an underground mall facility, the travel route via the parking lot is searched. However, even if the destination is not an underground mall facility, the travel via the parking lot is performed. The route may be searchable. In this case, for example, it may be possible to select whether or not to use a travel route via a parking lot by a user operation or a user setting.
