  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 device, and a wearable terminal used by a user.

  The user can search the route from the departure place to the destination in the route search server 20 by operating the client terminal 10 and inputting search conditions such as a desired departure place and destination. Then, the client terminal 10 displays the route selected by the user among the searched routes on the map. This allows the user to travel from the departure point to the destination according to the route displayed on the map.

  The route includes the place of departure and the destination. Also, the route may include one or more via points.

  Here, a route (or a partial route) indicating a destination from a departure place to a transit place, a transit way from the transit place, a transit way to a destination, or a departure place to a destination is referred to as a section. And, in the route, the transportation means is associated with the section. That is, the route includes at least a departure place and a destination, and transportation means for each section.

  For example, in the case of a route including one transit point, the route is a first section indicating a partial path from the departure point to the transit point, and a second section indicating a partial path from the transit point to the destination And are included. Then, for example, the first section is associated with the transportation means "train", and the second section is associated with the transportation means "walk". In this case, the user moves on the “train” in the first section, and moves on the “walk” in the second section.

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

  The client terminal 10 includes an input unit 101, a display control unit 102, and a communication unit 103. These units are 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 an input from a user. For example, the input unit 101 receives an input of a search condition for searching for a route (destination route) such as a departure place or a destination.

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

  The route information is information on a route, and includes information on a departure place, a destination, a passing place, a transportation means of a section, and the like. 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 exchanges information with the route search server 20. For example, the communication unit 103 transmits, to the route search server 20, search condition information indicating a search condition for searching for a route (going route). The communication unit 103 also receives search result information including the route information of the route (going route) 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 via point determination unit 202, a traffic determination unit 203, a return route information registration unit 204, a notification unit 205, and a communication unit 206. These units are realized by processing that one or more programs installed in the route search server 20 cause the CPU 21 to execute.

  In addition, 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.

  The search processing unit 201 searches for one or more routes (going routes) from the departure place to the destination based on the search condition information received from the client terminal 10. Here, the one or more destination routes searched by the search processing unit 201 will be referred to as “destination route candidates”. In addition, the departure place and the destination in the route to the destination are referred to as "destination of the destination" and "destination of the destination", respectively.

  In addition, the search processing unit 201 determines the departure place from the destination (ie, the departure place in the return route) (ie, the return route) based on the return route information stored in the return route information registration unit 204 described later. Search the route (return route) to the destination in In addition, the departure place and the destination in the return route will be referred to as "return departure place" 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 pieces of route information which are information on candidates for a route to go, and a map on the client terminal 10. And map information which is information. Further, the search result information indicating the search result based on the return path information by the search processing unit 201 includes, for example, route information which is information on a return route and map information.

  The via point determination unit 202 determines whether or not the route selected by the user (denoted as “selected route”) among the candidates for the destination route goes through the “parking lot”. That is, the via point determination unit 202 determines whether or not the information on the via point indicating “parking lot” is included in the route information of the selected route.

  When it is determined that the selected route does not go through the "parking lot" by the transit point determination unit 202, the traffic determination unit 203 determines whether the transportation means of the last section of the going route is a predetermined transportation means or not Do. Here, the last section of the going route means the partial route from the last passing place to the destination if the going route includes one or more passing places, and the going route is the passing place When not included, it refers to the route from the place of departure to the destination.

  In the present embodiment, "car" is assumed as the predetermined transportation means. However, the predetermined means of transportation is not limited to the "car", but may be any of various means of transportation such as "bus", "train", and "aircraft".

  The return route information registration unit 204 creates return route information based on the route information and the like of the selected route according to the determination results of the transit point determination unit 202 and the traffic determination unit 203, and registers the return route information in the return route information storage unit 207.

  When the user sets the date and time of return in advance, the notification unit 205 transmits a notification for searching for a return route to the client terminal 10 of the user. In the route search system 1 according to the present embodiment, when a search instruction for a return route is issued by the client terminal 10 receiving the notification, the route search server 20 searches for a return route.

  The communication unit 206 exchanges information with the client terminal 10. For example, the communication unit 206 receives search condition information from the client terminal 10.

  The return path information storage unit 207 stores the return path information registered by the return path information registration unit 204. Return route information is information for searching a return route, and information on a return departure location, a return destination, a transit route via a return route, transportation means of the first section in the return route, etc. included. Here, when the return route includes one or more vias, the first section means a partial route from the return starting point to the first via, and the return route does not include the via In the case of return, it says the route from the departure place to the return destination.

  In the return path information registration unit 204, the return path 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 which is information for causing the client terminal 10 to display a map. Map information is information for causing the client terminal 10 to display a map.

  The map information is classified, for example, by types of display objects such as green spaces, rivers, roads, railroads, prefectures, etc., and is managed by information segmented in known mesh shapes such as latitude and longitude. Then, the map information classified for each type of display target is displayed by drawing 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 in which the 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.

«Searching process of route to go»
First, a process of searching for a route (destination route) from a desired departure place to a destination by the user operating the client terminal 10 will be described with reference to FIG. FIG. 4 is a sequence diagram of an example of the process of searching for a destination route according to the present embodiment.

  The user operates the client terminal 10 to input a search condition for searching for an outgoing route. 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. 5 (a). Then, the user inputs the transportation means 1101, the departure place 1102 to the destination, the destination 1103 to the destination, and the date 1104 and presses the route search button 1105. As a result, the input unit 101 of the client terminal 10 selects “depart by car” designated by the transportation means 1101, “station A” designated as the departure point 1102 to be bound, and “○” designated as the destination point 1103 to be bound It accepts the input of the search condition including the “park” and the current time specified in the date and time 1104. Note that, for example, the current position of the client terminal 10 determined based on the radio wave received from the GPS may be designated as the departure point 1102 of the destination.

  Here, the transportation means 1101 designates the transportation means to be used first at the departure place 1102 (that is, the transportation means of the first section). For example, when “depart by car” is designated as the transportation means 1101, it means that the user starts moving using a car from the departure place 1102 of the way. Similarly, when "depart on foot" is designated as the transportation means 1101. The user means to start moving on foot from the departure point 1102 of the destination. In this embodiment, the transportation means 1101 will be described as "departing by car" is designated.

  In addition, in FIG. 5 (a), although the transportation means of the first area, the departure place of going, the destination of going, and the date and time were designated as a search condition, it is not restricted to this. For example, a via point or the like may be specified as the search condition. Further, for example, detailed search conditions such as whether or not to use an aircraft, and whether to use a pay express may be specified.

  Next, when the input unit 101 receives the input of the search condition, the communication unit 103 of the client terminal 10 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 to go, the destination place to go, and the current time.

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

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

  Next, when the display control unit 102 of the client terminal 10 receives the search result information by the communication unit 103, the display control unit 102 displays the candidate of the going route 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. The search result screen 1200 shown in FIG. 5B is a diagram showing a case where three route destinations are searched by the search processing unit 201 of the route search server 20, and the route candidate 1201 for the route The route candidate 1202 and the going route candidate 1203 are displayed. As described above, the client terminal 10 displays a list of one or more destination routes searched for by the route search server 20 based on the search condition.

  Next, the user selects a desired destination route candidate from the destination options displayed on the client terminal 10 (step S406). Then, the display control unit 102 of the client terminal 10 causes the details of the selected route to be displayed based on the route information of the selected destination 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. 5C. . In the route detail screen 1300 shown in FIG. 5C, the details of the route 1201 (selected route) of the route selected by the user are displayed. As a result, the user can know the transportation means, the arrival and departure times, and the like in each section of the route (selected route) selected by the user.

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

  For example, in the route detail screen 1300 shown in FIG. 5C, when the date and time setting button 1301 for returning by the user is pressed, the client terminal 10 displays a setting screen 1400 for the date and time for returning shown in FIG. Then, the user sets in the date and time 1401 the date and time to return from the destination (or the date and time on which the user wants to search for a return route). A destination 1103 for going to and a departure point 1102 for going to which are set in FIG. 5A are respectively set as the departure point 1402 of return and the destination 1403 of return. By setting the return date and time setting screen 1400 shown in FIG. 6A, the user can set the route (return route) from the return departure point 1402 to the return destination 1403 on the date and time designated as the date and time 1401. You will be able to receive notifications for searching.

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

  For example, when the guidance start button 1302 is pressed by the user in 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, the route 1501 for going based on the route information of the selected route is displayed on the map based on the map information received in step S404. This allows the user to know the route from the desired destination to the destination (destination route).

  The map information of the map displayed on the route guidance screen 1500 shown in FIG. 6B is, for example, the route search server at the timing when the guidance start button 1302 is pressed on the route detail screen 1300 shown in FIG. 5C. You may get from 20. Further, the client terminal 10 may not have map information acquired from the route search server 20, and the client terminal 10 may have map information.

  Next, when route guidance of the selected route is started, the communication unit 103 of the client terminal 10 receives 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. 1401) and the route information of the selected route are transmitted to the route search server 20 (step S410).

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

«Return process registration process»
Next, the details of the process (the return path information registration process) in step S411 in FIG. 4 will be described with reference to FIG. FIG. 7 is a flowchart of an example of return path information registration processing according to the present embodiment. As described above, the return route information includes information on the return departure location, the return destination, the transportation means of the first section, and the passing location (the return route destination) via the return route. The return path information registration process described below is a process of setting each of these pieces of information, creating return path information, and registering the return path information in the return path information registration unit 204.

  First, the return route information registration unit 204 of the route search server 20 sets the departure place and destination destination included in the route information of the selected route as the return destination and return departure place of the return route information, respectively (Step S701).

  Specifically, when the departure place of the departure is "A station" and the departure place of the departure is "○ × park", as shown in FIG. 8, the departure place 2073 of the return route information 207D is ", Set the return destination 2074 as" A station ".

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

  If it is determined in step S702 that the via route determination unit 202 determines 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 at the return route of return route information. The transportation means of the section of is set to "walk" (step S703).

  Specifically, when the via route "XXX parking" is included in the selected route, as shown in FIG. 8, the route site 2076 on the return of the return route information 207D is "XXX parking", and the transportation means 2075 of the first section Set as "walk". In this way, if you are going through the parking lot on the way, it is considered that the car is parked in the parking lot on the way, so the means of transportation in the first section of the way back is "walk" It is set.

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

  Specifically, when the user ID is "user001" and the date is "2013/01/15 16:30", as shown in FIG. 8, the user ID 2071 of the return path information 207D is "user001", the date 2072 is " 2013/01/15 16:30 "is set. 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 S702, when it is determined by the via point determination unit 202 that the selected route is not via the parking lot, the traffic determination unit 203 of the route search server 20 determines that the transportation means of the last section of the selected route is "car". It is determined whether or not it is (step S705).

  In step S705, when it is determined by the traffic determination unit 203 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 return route information to "car". And (step S706). In this way, if it is determined that the transportation route of the last section is a "car" when passing through the parking lot on the way to the destination, it is considered that the car will depart from the place of return on the way home. The transportation means of the first section of the return route information is set to "car". At this time, the return route of return route information is not set.

  In step S705, when it is determined by the traffic determination unit 203 that the transportation means in the last section of the selected route is not "car", the return route information registration unit 204 sets the transportation means in the first section of return route information as "walk". (Step S707). In this way, if it is not going through the parking lot and the transportation means of the last section is not a "car" on the way of going, it is thought that the way back will depart on foot from the place of departure on the way back. The transportation mode of the first section of information is set to "walk". At this time, the return route of return route information is not set.

  As described above, in the present embodiment, return route information for searching for a return route is registered based on the route information and the like of the selected route. Although FIG. 8 shows, as an example, return route information 207D including one return route point, the present invention is not limited to this, and two or more return route points may be included in return route information 207. .

  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 described above, the route search server 20 searches the return route by the search processing unit 201 based on the registered return route information and stores the storage unit. You may memorize it.

<< notification processing of the date and time of return >>
Next, processing for notifying the user of the route for return when the date and time of return set by the user is reached will be described with reference to FIG. FIG. 9 is a flowchart of an example of notification processing of the date and time of return according to the present embodiment. In addition, the notification process of the date and time of the return demonstrated below is performed in the path | route search server 20 for every predetermined time (for example, every one second).

  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 the acquired current date and time is a return date and time (step S902) . That is, the notification unit 205 determines whether or not the current date and time has become the return date and time set in the return route information registered in the return route information storage unit 207.
