  The client terminal 10 is various information processing apparatuses such as a smartphone, a mobile phone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a game machine, and a wearable terminal used by a user.

  The user can search the route from the departure point to the destination in the route search server 20 by operating the client terminal 10 and inputting search conditions such as a desired departure point and destination. And the client terminal 10 displays the path | route selected by the user among the searched paths | routes on a map. Thereby, the user can go from the departure place to the destination according to the route displayed on the map.

  The route includes a departure place and a destination. Further, the route may include one or more waypoints.

  Here, a route (or partial route) indicating a route from a departure point, a route point to a next route point, a route point to a destination point, or a departure point to a destination point is referred to as a section. In the route, the transportation means is associated with the section. That is, the route includes at least a departure point, a destination, and a transportation means for each section.

  For example, in the case of a route including one waypoint, the route includes a first section indicating a partial route from the departure point to the route point, and a second section indicating a partial route from the route point to the destination. And are included. For example, the transportation means “train” is associated with the first section, and the transportation means “walk” is associated with the second section. In this case, the user moves by “train” in the first section, and moves by “walking” in the second section.

  The route search server 20 is an information processing device that searches for routes. The route search server 20 searches for a route from the departure point to the destination (route to go) based on the search condition input by the user at the client terminal 10.

  Further, the route search server 20 searches for a route (return route) corresponding to the route to go in response to a request from the user. At this time, if the route search server 20 passes through a predetermined facility as a waypoint in the route to go, the route search server 20 searches for a return route via the route point.

<Functional configuration>
Next, the functional configuration of the route search system 1 according to the present embodiment will be described with reference to FIG. FIG. 3 is a functional configuration diagram of an example of a route search system according to the present embodiment.

  The client terminal 10 includes an input unit 101, a display control unit 102, and a communication unit 103. Each of these units is realized by processing that one or more programs installed in the client terminal 10 cause the CPU 11 to execute.

  The input unit 101 receives input from the user. For example, the input unit 101 receives input of search conditions for searching for a route (route to go) such as a departure point or a destination.

  The display control unit 102 displays various screens. For example, the display control unit 102 displays a route from the departure place to the destination on the map based on the map information and the route information received from the route search server 20.

  The route information is information related to the route, and includes information such as a departure point, a destination, a waypoint, and a section of transportation. The map information is information stored in a map information storage unit 208 described later, and is information for causing the client terminal 10 to display a map.

  The communication unit 103 transmits / receives information to / from the route search server 20. For example, the communication unit 103 transmits search condition information indicating a search condition for searching for a route (route to go) to the route search server 20. In addition, the communication unit 103 receives search result information including route information of a route (route to go) searched by the route search server 20 based on the search condition information.

  The route search server 20 includes a search processing unit 201, a waypoint determination unit 202, a traffic determination unit 203, a return route information registration unit 204, a notification unit 205, and a communication unit 206. Each of these units is realized by processing that one or more programs installed in the route search server 20 cause the CPU 21 to execute.

  The route search server 20 includes a return route information storage unit 207 and a map information storage unit 208. Each of these storage units can be realized by the storage device 24 or a storage device connected to the route search server 20 via a network.

  Based on the search condition information received from the client terminal 10, the search processing unit 201 searches for one or more routes (routes to go) from the departure point to the destination. Here, one or more outbound routes searched by the search processing unit 201 are represented as “bound route candidates”. In addition, the departure place and the destination in the route to go are expressed as “the departure place” and “the destination”, respectively.

  In addition, the search processing unit 201 uses a return route information stored in the return route information registration unit 204, which will be described later, to a departure point (that is, a return route) from a destination (ie, a departure point on a return route). Search for the route (return route) to the destination at. The departure point and the destination on the return route are represented as “return departure point” and “return destination”, respectively.

  The search result information indicating the search result based on the search condition information by the search processing unit 201 includes, for example, one or more route information that is information related to a candidate for the route to go to display a map on the client terminal 10. And map information that is information. Further, the search result information indicating the search result based on the return route information by the search processing unit 201 includes, for example, route information that is information related to the return route and map information.

  The waypoint determination unit 202 determines whether or not the route selected by the user (represented as “selected route”) among the route candidates to go through “parking lot”. That is, the waypoint determination unit 202 determines whether or not the route information indicating “parking lot” is included in the route information of the selected route.

  When the route determination unit 202 determines that the selected route does not pass through the “parking lot”, the traffic determination unit 203 determines whether or not the transportation means in the last section of the route to go is a predetermined transportation means. To do. Here, the last section of the route is the partial route from the last waypoint to the destination if the route contains one or more waypoints. If not included, it refers to the route from the origin to the destination.

  In the present embodiment, the description will be made assuming that the predetermined transportation means is a “car”. However, the predetermined transportation means is not limited to “car”, and may be various transportation means such as “bus”, “train”, and “aircraft”.

  The return route information registration unit 204 creates return route information based on the route information of the selected route in accordance with the determination result of the waypoint determination unit 202 or the traffic determination unit 203 and registers it in the return route information storage unit 207.

  When the return date and time is set in advance by the user, the notification unit 205 transmits a notification for searching the return route to the client terminal 10 of the user. In the route search system 1 according to the present embodiment, the return route is searched in the route search server 20 when the client terminal 10 that has received the notification issues a return route search instruction.

  The communication unit 206 transmits / receives information to / from the client terminal 10. For example, the communication unit 206 receives search condition information from the client terminal 10.

  The return route information storage unit 207 stores the return route information registered by the return route information registration unit 204. Return route information is information for searching a return route, and includes information such as a return departure point, a return destination, a transit point via the return route, and a transportation method of the first section in the return route. included. Here, the first section refers to a partial route from the return starting point to the first stop point when the return route includes one or more stop points, and the return route does not include the stop point. In some cases, it refers to the route from the return origin to the return destination.

  In the return route information registration unit 204, the return route information is stored in association with a user ID or the like that is information for uniquely identifying the user of the client terminal 10.

  The map information storage unit 208 stores map information that is information for displaying a map on the client terminal 10. The map information is information for displaying a map on the client terminal 10.

  The map information is classified according to the type of display target such as green spaces, rivers, roads, railroads, prefectures, etc., and is managed by information in which latitude and longitude are separated in a known mesh shape. The map information classified for each type of display target is displayed by being drawn for each mesh on a layer predetermined for each type according to the scale. Therefore, the map displayed on the client terminal 10 is displayed by combining and overlapping one or more mesh-like layers on which map information classified for each type of display object is drawn.

<Details of processing>
Next, details of processing of the route search system 1 according to the present embodiment will be described.

≪Route search process≫
First, a process in which the user operates the client terminal 10 to search for a route from the desired departure point to the destination (route to go) will be described with reference to FIG. FIG. 4 is a sequence diagram illustrating an example of a route search process according to the present embodiment.

  The user operates the client terminal 10 to input search conditions for searching for a route to go. Then, the input unit 101 of the client terminal 10 receives the search condition input from the user (step S401).

  For example, the user operates the client terminal 10 to display a route search screen 1100 shown in FIG. Then, the user inputs the transportation means 1101, the departure place 1102, the destination 1103, and the date and time 1104, and presses the route search button 1105. As a result, the input unit 101 of the client terminal 10 causes the “departure by car” designated as the transportation means 1101, the “A station” designated as the destination 1102, and the “○” designated as the destination 1103 to the destination. The input of the search condition including “× park” and the current time specified in the date and time 1104 is accepted. Note that the current location of the client terminal 10 measured based on the radio wave received from the GPS may be specified as the departure place 1102, for example.

  Here, the transportation means 1101 designates the transportation means to be used first in the departure place 1102 (that is, the transportation means of the first section). For example, when “departure by car” is designated as the transportation means 1101, it means that the user starts moving from the departure place 1102 using a car. Similarly, when “depart on foot” is designated as the transportation means 1101. The user means to start moving on foot from the departure place 1102 to go. In the present embodiment, it is assumed that “departure by car” is specified for the transportation means 1101.

  In FIG. 5A, as the search condition, the transportation means of the first section, the departure place of departure, the destination of departure, and the date and time are specified, but this is not restrictive. For example, a waypoint may be specified as the search condition. Further, for example, it may be possible to specify detailed search conditions such as whether to use an aircraft or whether to use a paid express.

  Next, when the communication unit 103 of the client terminal 10 receives an input of a search condition from the input unit 101, the communication unit 103 transmits search condition information indicating the search condition to the route search server 20 (step S402). Here, it is assumed that the search condition information includes information indicating the transportation means of the first section designated by the user in step S401, the departure place, the destination, and the current time.

  Next, when the search processing unit 201 of the route search server 20 receives the search condition information from the communication unit 206, the search processing unit 201 receives one or more routes from the departure place to the destination based on the search condition information. A (route candidate) is searched (step S403). And the communication part 206 of the route search server 20 transmits the search result information which shows a search result by the search process part 201 to the client terminal 10 (step S404).

  Note that the search result information includes one or more pieces of route information indicating information related to the route candidate. In addition, the search result information may include map information for displaying a map corresponding to the route to go based on the route information included in the search result information.

  Next, when the search result information is received by the communication unit 103, the display control unit 102 of the client terminal 10 displays the route candidate searched as the search result based on the route information included in the search result information. (Step S405).

  For example, the display control unit 102 displays a search result screen 1200 shown in FIG. A search result screen 1200 shown in FIG. 5B is a diagram illustrating a case where three search route candidates are searched by the search processing unit 201 of the route search server 20. A route candidate 1202 and a route candidate 1203 are displayed. As described above, the client terminal 10 displays a list of one or more route candidates that are searched by the route search server 20 based on the search condition.

  Next, the user selects a desired route candidate from among the route candidates displayed on the client terminal 10 (step S406). Then, the display control unit 102 of the client terminal 10 displays the details of the selected route based on the route information of the selected route candidate (selected route) (step S407).

  For example, in the search result screen 1200 shown in FIG. 5B, when the route candidate 1201 is selected by the user, the client terminal 10 displays the route detail screen 1300 shown in FIG. . In the route detail screen 1300 shown in FIG. 5C, the route details of the route candidate 1201 (selected route) selected by the user are displayed. Thereby, the user can know the transportation means, the arrival and departure times, etc. in each section of the route (selected route) selected by the user.

  Next, when the user performs an operation for setting the return date and time, the display control unit 102 of the client terminal 10 displays a screen for setting the return date and time (step S408).

  For example, in the route detail screen 1300 shown in FIG. 5C, when the user sets the return date / time setting button 1301, the client terminal 10 displays the return date / time setting screen 1400 shown in FIG. 6A. Then, the user sets the date / time 1401 as the date / time when he / she returns from his / her destination (or the date / time when he / she wants to search the return route). Note that the destination 1103 and the destination 1102 set in FIG. 5A are set in the return destination 1402 and the return destination 1403, respectively. By setting the return date and time setting screen 1400 shown in FIG. 6A, the user can set a route (return route) from the return starting point 1402 to the return destination 1403 at the date and time specified in the date and time 1401. You can receive notifications for searching.

  Next, when the user performs an operation for starting guidance of the route to go, the display control unit 102 of the client terminal 10 displays the route (selected route) selected by the user on the map, and the route is displayed. Guidance is started (step S409).

  For example, when the user presses the guidance start button 1302 on the route detail screen 1300 shown in FIG. 5C, the client terminal 10 displays the route guidance screen 1500 shown in FIG. To start. In the route guidance screen 1500 shown in FIG. 6B, for example, a route 1501 based on the route information of the selected route is displayed on the map based on the map information received in step S404. Thereby, the user can know the route from the desired departure place to the destination (the outgoing route).

  Note that the map information of the map displayed on the route guidance screen 1500 shown in FIG. 6B is, for example, a route search server at the timing when the guidance start button 1302 is pressed on the route detail screen 1300 shown in FIG. You may acquire from 20. Further, the client terminal 10 does not acquire the map information from the route search server 20, but the client terminal 10 may have the map information.

  Next, when the route guidance for the selected route is started, the communication unit 103 of the client terminal 10 and the user ID of the user of the client terminal 10 and the date and time set in step S408 (the date and time shown in FIG. 6A). 1401) and the route information of the selected route are transmitted to the route search server 20 (step S410).

  Finally, when the communication unit 206 receives the user ID, the date and time, and the route information, the route search server 20 performs a return route information registration process (step S411). That is, the route search server 20 creates return route information based on the received information and registers it in the return route information storage unit 207. Details of the return path information registration process will be described later.

≪Return information registration process≫
Next, details of the process of step S411 in FIG. 4 (return path information registration process) will be described with reference to FIG. FIG. 7 is a flowchart of an example of a return route information registration process according to the present embodiment. Note that, as described above, the return route information includes information on the return departure point, the return destination, the transportation means of the first section, and the transit point (return route) via the return route. The return path information registration process described below is a process of setting each of these pieces of information to create return path information and registering it in the return path information registration unit 204.

  First, the return route information registration unit 204 of the route search server 20 sets a return destination and a return destination included in the route information of the selected route as a return destination and a return start point, respectively, of the return route information (step) S701).

  Specifically, if the departure place is “Station A” and the departure place is “Ox Park”, as shown in FIG. 8, the return origin 2073 of the return route information 207D is set to “Ox Park”. "The return destination 2074 is set as" Station A ".

  Next, the waypoint determination unit 202 of the route search server 20 determines whether or not the route information indicating the parking lot is included in the route information of the selected route (step S702). That is, the waypoint determination unit 202 determines whether the selected route (the route to go) passes through the parking lot.

  When it is determined by the waypoint determination unit 202 in step S702 that the selected route passes through the parking lot, the return route information registration unit 204 of the route search server 20 sets the parking lot as a return route of the return route information. The transportation means for the section is “walking” (step S703).

  Specifically, when the route “XX parking” is included in the selected route, as shown in FIG. 8, the route 2076 of the return route information 207D is set to “XX parking”, and the transportation means 2075 in the first section. Is set to “walk”. In this way, if you are going through the parking lot on the route to go, it is considered that the car is parked in the parking lot on the route to go, so the transportation for the first section on the return route is `` walk '' Is set.

  Then, the return route information registration unit 204 of the route search server 20 registers the received user ID and date and time in the return route information storage unit 207 in association with the return route information (step S704).

  Specifically, when the user ID is “user001” and the date and time is “2013/01/15 16:30”, as shown in FIG. 8, the user ID 2071 of the return path information 207D is “user001” and the date and time 2072 is “ 2013/01/15 16:30 ". Then, the return route information registration unit 204 registers the return route information 207D thus created in the return route information registration unit 204.

  In step S <b> 702, when the waypoint determination unit 202 determines that the selected route does not pass through the parking lot, the traffic determination unit 203 of the route search server 20 indicates that the transportation means of the last section of the selected route is “car”. It is determined whether or not (step S705).

  In step S705, when the traffic determination unit 203 determines that the transportation means of the last section of the selected route is “car”, the return route information registration unit 204 sets the transportation means of the first section of the return route information to “car”. (Step S706). In this way, if it is not going through the parking lot on the route to go and the transportation means in the last section is `` car '', it is considered that the return route will start by car from the return departure place, The transportation means of the first section of the return route information is set to “car”. At this time, the return route of the return route information is not set.

  In step S705, when the traffic determination unit 203 determines that the transportation means of the last section of the selected route is not “car”, the return route information registration unit 204 sets the transportation means of the first section of the return route information as “walking”. (Step S707). In this way, if you do not go through the parking lot on the route to go, and the transportation means of the last section is not `` car '', it is considered that you will depart on foot from the departure place on the return route. The transportation mode of the first section of information is set to “walking”. At this time, the return route of the return route information is not set.

  As described above, in the present embodiment, return route information for searching a return route is registered based on route information of a selected route. In FIG. 8, as an example, the return route information 207D including one return route is shown, but the present invention is not limited to this, and the return route information 207 may include two or more return routes. .

  In addition to the return route information, the route search server 20 may register a return route searched based on the return route information. That is, after the return route information is registered in the return route information registration process of FIG. 7, the route search server 20 searches the return route by the search processing unit 201 based on the registered return route information, and the storage unit You may memorize.

≪Return date notification process≫
Next, a process of notifying the user for searching for a return route when the return date and time set by the user is reached will be described with reference to FIG. FIG. 9 is a flowchart of an example of a return date notification process according to the present embodiment. Note that the return date and time notification process described below is executed at predetermined time intervals (for example, every second) in the route search server 20.

  First, the notification unit 205 of the route search server 20 acquires the current date and time (step S901).

  Next, the notification unit 205 of the route search server 20 refers to the return route information registered in the return route information storage unit 207, and determines whether or not the acquired current date is a return date (step S902). . That is, the notification unit 205 determines whether or not the current date / time is the return date / time set in the return route information registered in the return route information storage unit 207.

  In step S902, when the notification unit 205 does not determine that the current date is the return date, the route search server 20 ends the process.

  In step S902, when the notification unit 205 determines that the current date / time is the return date / time, the notification unit 205 of the route search server 20 confirms that the return date / time set in advance has been reached by the communication unit 206. The notification shown is transmitted to the client terminal 10 (step S903). At this time, the notification unit 205 transmits the notification to the client terminal 10 having the user ID included in the corresponding return path information.

  When the client terminal 10 receives the notification from the route search server 20, for example, a return route search notification screen 1600 shown in FIG. 10 is displayed. As a result, the user can search the return route when the return date and time set in advance is reached.

  Here, the user can search the return route based on the return route information by pressing the return route search button 1601 on the return route search notification screen 1600 shown in FIG.

  Thereby, in the route search system 1 which concerns on this embodiment, the optimal return route is searched in the date and time when a user returns.

  In the present embodiment, the case where the notification is transmitted to the client terminal 10 when the return date and time set in advance has been described has been described, but the present invention is not limited thereto. The route search system 1 sends a notification to the client terminal 10 when, for example, a preset return date and time is reached and a traffic jam occurs on the return route stored in the storage unit in advance. You can do it.

≪Return route search processing≫
Next, processing for searching for a return route will be described with reference to FIG. FIG. 11 is a sequence diagram illustrating an example of a return route search process according to the present embodiment.

  The user operates the client terminal 10 to specify a search for a return route. Then, the input unit 101 of the client terminal 10 accepts the specification of the search for the return route (step S1101).

  For example, the user can specify the search for the return route by pressing the return route search button 1601 on the return route search notification screen 1600 shown in FIG. 10 displayed on the client terminal 10. .

  Next, when the communication unit 103 of the client terminal 10 receives a search for a return route from the input unit 101, the communication unit 103 transmits the user ID of the user of the client terminal 10 to the route search server 20 (step S1102).

  When the search processing unit 201 of the route search server 20 receives the user ID through the communication unit 206, the search processing unit 201 acquires the return route information including the user ID from the return route information storage unit 207 (step S1103).

  Next, the search processing unit 201 of the route search server 20 searches for a return route based on the acquired return route information (step S1104).

  For example, if the search processing unit 201 obtains the return route information 207D shown in FIG. 8 in step S1103, the transportation means in the first section is “walking”, and the return route is “home parking”. Then, a return route from the return departure place “○ × park” to the return destination “A station” is searched.

  Thus, the route search server 20 according to the present embodiment searches for a return route based on the return route information. Therefore, the route search server 20 according to the present embodiment can search for the optimal return route in consideration of the traffic state at the preset return date and time, the operation status of public transportation, and the like.

  In other words, the route search server 20 according to the present embodiment searches the optimum route according to the return date and time as the return route, instead of using the same route as the going route as the return route. Moreover, the route search server 20 according to the present embodiment searches for a return route so as to pass through a predetermined facility that has been routed on the route to go, so that an optimal return is obtained even when, for example, park and ride is used. The route of is searched.

  Then, the communication unit 206 of the route search server 20 transmits search result information including the route information of the return route searched by the search processing unit 201 to the client terminal 10 (step S1105).

  Next, when receiving the search result information from the communication unit 103, the display control unit 102 of the client terminal 10 displays the details of the return route based on the route information included in the search result information (step S1106).

  For example, the client terminal 10 displays a route detail screen 1700 for the return route shown in FIG. In the route detail screen 1700 shown in FIG. 12, details of the return route searched based on the return route information 207D shown in FIG. 8 are displayed.

  That is, on the route detail screen 1700 shown in FIG. 12, the transportation means of the first section is “walking”, the return route “XXX parking” is passed, and the return departure location “XX park” is returned. The details of the return route to the destination “A station” are displayed.

  Finally, the display control unit 102 of the client terminal 10 displays the searched return route on the map and starts route guidance (step S1107).

  For example, when the guidance start button 1701 is pressed by the user on the route details screen 1700 shown in FIG. 12, the client terminal 10 displays the searched return route on the map and starts route guidance. As a result, the user can return on the optimal return route.
