Description

  The present invention relates to an information processing device, an information processing system, an information processing method, an information processing program, and a terminal device that search for a route from a departure place to a destination.

There is known a navigation device that searches and guides a route from a departure place to a destination.
In recent years, navigation systems that transmit a route search request from a terminal device such as a mobile phone to a route search server and display the route searched by the route search server on the terminal device have also been used. Such a navigation system is suitable for a pedestrian to carry and use.

  In the navigation system for pedestrians, comprehensive route guidance including transportation such as trains and buses is performed in addition to roads. In the case of a route using a plurality of transportation facilities, information on arrival time and departure time at a transfer station is obtained as a result of route search. In addition, a navigation system that calculates and guides not only the time required for transfer but also waiting time has been proposed (for example, Patent Document 1).

JP 2007-271283 A

  In such a navigation system, for example, when departing at night, route information using the first train may be obtained after waiting for hours at a transit station on the way. Thus, there are many cases where the route that needs to wait for a long time at the transfer station is not the route desired by the user, and is not appropriate. In this case, the user needs to search again by resetting the departure time.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an information processing device, an information processing system, an information processing method, an information processing program, and a terminal device that can easily present an appropriate route to a user. It is to provide.

  According to one aspect of the present invention, there is provided an information processing system including an acquisition unit that acquires route information from a departure place to a destination, and an output unit that outputs the route information. According to the unit date included in the same day, when the departure date and arrival date of the route information are different, the output means outputs the route information and the departure date and arrival date of the route information are different. The information processing system is characterized in that it outputs at least one of the following information, information on another route on which the departure date and arrival date are the same date, and information that prompts reacquisition of route information.

  According to the present invention, it is determined whether or not the search result is appropriate. If the search result is not appropriate, the route correction information is generated, so that an appropriate route can be easily presented to the user.

  Embodiments according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a schematic block diagram of a route search system according to an embodiment of the present invention. The route search system includes a terminal device 1 and a server (information processing device) 2. As illustrated, the terminal device 1 communicates with the server 2 via the network 3.

  The terminal device 1 is used by a user and is, for example, a mobile electronic device such as a mobile phone, a smartphone or a tablet terminal, or a stationary electronic device such as a car navigation device. The network 3 may be either a wired line or a wireless line, and the type and form of the line are not limited.

  The terminal device 1 includes a communication unit 11 and a control unit 12.

  The communication unit 11 is an interface that transmits and receives information between the control unit 12 and the server 2 via the network 3.

  The control unit 12 includes an operation input unit 121, a display unit (presentation unit) 122, a search condition setting unit 123, a search request transmission unit 124, a route correction request transmission unit 125, and an information reception unit 126.

  The operation input unit 121 is an interface for a user to input an operation to the terminal device 1, and is, for example, a keyboard, a touch pad, a dial button, or the like in a mobile electronic device, or a touch panel or a microphone in a stationary electronic device.

  The display unit 122 displays a screen for setting search conditions, search results, and the like, and is a liquid crystal display, for example. In addition to the display unit 122, a voice output unit that outputs voice for route guidance may be provided.

  The search condition setting unit 123 sets a search condition from the user via the operation input unit 121. The search condition of this embodiment includes a departure place and a destination, and a departure date / time or arrival date / time.

  The search request transmission unit 124 transmits a search request including a search condition to the server 2 and requests the server 2 to perform a route search based on the search condition.

  The route correction request transmission unit 125 is one of the features of the present embodiment. When the route searched by the server 2 is inappropriate, a request to correct the route is sent from the communication unit 11 via the network 3. Send to server 2.

  The information receiving unit 126 receives route information and route correction information (described later) sent from the server 2 from the communication unit 11 via the network 3 and displays them on the display unit 122.

  On the other hand, the server 2 includes a communication unit 21, a storage unit 22, and a control unit 23.

  The communication unit 21 is an interface that transmits and receives information to and from the terminal device 1 via the network 3.

The storage unit 22 stores a route network database 221 including route network information. The route network information is information that defines a traffic network such as a railroad or a bus or a road network.
Information on the transportation network includes route information, timetable information, toll information, etc. of transportation facilities. The information on the road network is expressed by a combination of node data that is a node on the road network expression such as an intersection and link data that is a road section between nodes.

  The control unit 23 includes a route network information acquisition unit 231, a search request reception unit 232, a route search unit 233, a route determination unit 234, a route correction information generation unit 235, and an information transmission unit 236.

  The route network information acquisition unit 231 is an interface with the storage unit 22 that accesses the storage unit 22 and acquires the route network information from the route network database 221.

  The search request receiving unit 232 receives a search request including a search condition transmitted from the terminal device 1 from the communication unit 21 via the network 3.

  In response to the search request, the route search unit 233 performs a route search based on the route network information and the search condition, and generates route information indicating the route. In the present embodiment, an example of searching for a route using at least two trains is shown. The route information includes a transfer waiting time from one train to the next train.

  The route determination unit 234 determines whether or not the searched route is appropriate based on the transfer waiting time. More specifically, when the route determination unit 234 includes a transfer waiting time of a predetermined time or longer, the route searched is one of the second and subsequent trains, and the first train is not used in time for the last train. Judged as an inappropriate route. When using the first train for transfer, the user must wait for a long time until the first train. The present embodiment is intended to easily avoid such inconvenience. In the present specification, for a given station on one route, the train that departs earliest in the early morning is called “first train”, and the train that departs latest in the middle of the night is called “last train”.

  When the route correction information generation unit 235 determines that the route is inappropriate, the route correction information generation unit 235 generates information to that effect. Furthermore, when the route correction information generation unit 235 determines that the route is inappropriate, the transfer waiting time is shortened by changing the departure date / time or arrival date / time included in the search condition in response to the route correction request. The route is searched again, and route correction information is generated.

  When it is determined that the route is not appropriate, the information transmission unit 236 transmits the information to that effect and the route correction information from the communication unit 21 to the information reception unit 126 of the terminal device 1 via the network 3. .

  FIG. 2 is a flowchart illustrating an example of a processing operation of the route search system. In the figure, the subject of the process whose numerical value following “S” is “1” is the terminal device 1, and the subject of the process whose value is “2” is the server 2.

  First, the search condition setting unit 123 of the terminal device 1 displays a search condition setting screen on the display unit 122. In response to this, the user operates the search condition setting screen via the operation input unit 121 to set the search condition (step S101). The search condition includes a departure place and a destination, and a departure date / time or arrival date / time. Subsequently, the search request transmission unit 124 transmits a search request having a search condition from the communication unit 11 to the search request reception unit 232 of the server 2 via the network 3 (step S102).

When the search request receiving unit 232 receives the search condition (step S203), the route search unit 233, based on the route network information acquired by the route network information acquisition unit 231 and the search condition, routes from the departure point to the destination. Search is performed to generate route information (step S204). When the departure date and time is set as the search condition, the route search unit 233 searches for a route that leaves the departure place on the departure date and time. When arrival date and time is set as the search condition, the route search unit 233 searches for a route that arrives at the destination by the arrival date and time.
The route information includes a transfer waiting time when changing trains.

  When the route information obtained as a result of the search includes a transfer waiting time of a predetermined time or longer (YES in step S205), the route determination unit 234 uses the first train because the transfer is not in time for the last train. Judged as an inappropriate route. On the other hand, when the transfer waiting time longer than the predetermined time is not included (NO in step S205), the route determination unit 234 determines that the route is appropriate.

  The predetermined time is determined based on an average transfer waiting time at the transfer station and a required time obtained by an average search in advance from the departure station to the arrival station. The average search is a method of searching for a route without specifying a time, and the average time is used for both the time required for transportation and the transfer time. Thereby, the route determination unit 234 can accurately determine whether the route uses the first train.

  If it is determined that the route is appropriate, the information transmission unit 236 transmits the route information from the communication unit 21 to the information reception unit 126 of the terminal device 1 via the network 3 (step S213).

  On the other hand, when it is determined that the route is not appropriate, the route correction information generation unit 235 generates information indicating that the route is inappropriate, and the information transmission unit 236 indicates that the route information is inappropriate. Information is transmitted from the communication unit 21 to the information receiving unit 126 of the terminal device 1 via the network 3 (step S206).

  When the information receiving unit 126 receives the route information and information indicating that the route is inappropriate (step S107), the display unit 122 displays these (step S108).

  At this time, when the terminal device 1 receives a route correction request from the user via the operation input unit 121 (YES in step S109), the route correction request transmission unit 125 transmits the route correction via the network 3 from the communication unit 11. The request is transmitted to the search request receiving unit 232 of the server 2 (step S110).

  When the search request reception unit 232 receives the route correction request (step S211), the route correction information generation unit 235 performs route correction processing (step S212). More specifically, the route correction information generation unit 235 changes the departure date / time or arrival date / time of the search condition so that the transfer waiting time is shortened, in other words, the first train is not used for the transfer, and the route network information is used. The route from the departure point to the destination is searched again, and new route information is generated as correction processing information. Specific contents of the route correction process in step S212 will be described in detail later.

  Then, the information transmission unit 236 transmits new route information from the communication unit 21 to the information reception unit 126 of the terminal device 1 via the network 3 (step S213).

  When the information receiving unit 126 receives new route information (step S114), the display unit 122 displays this (step S115). As described above, the route search system can present to the user a route with a short transfer waiting time that does not use the first train as the second and subsequent trains.

  The route correction process in step S212 differs depending on whether a departure date and time or an arrival date and time is set as a search condition. First, the former will be described.

  If the departure date and time is set, the user is considered to want to arrive at the destination during the departure date. Therefore, the route search system presents the route to the user when there is a route that can arrive during the departure date as follows, and presents the route that arrives at the earliest possible time on the next day if it cannot arrive.

  FIG. 3 is a diagram illustrating an example of a screen displayed on the display unit 122 when the departure date and time is set and the route information for crossing over the last train is obtained. This figure corresponds to step S108 in FIG. 2, and is obtained by performing a route search with the departure point set at A station, the destination set at C station, and the departure date and time set at 23:00 on October 10, 2011. Route information is illustrated. According to this route information, the transfer waiting time is very long at 6 hours 58 minutes in order to use the first train Q1 when transferring at station B. Therefore, in addition to the route information, the display unit 122 also displays information 50 indicating that the route is inappropriate and prompting the route to be searched again.

When the user selects the information 50 via the operation input unit 121 (YES in step S109 in FIG. 2), a route correction request, in this case, a request for searching for a route arriving during the departure date is sent from the terminal device 1 to the server. 2 (step S110). In response to this route correction request, the server 2 performs the following route correction processing.
FIG. 4 is a flowchart illustrating an example of a route correction process when the departure date and time is set in the search condition. First, the route correction information generation unit 235 searches again for a route that arrives at the destination during the departure date, regardless of the set departure date and time (step S251). For this purpose, for example, the route correction information generation unit 235 searches for the route that arrives at the latest destination during the departure date.

  When there is a route arriving during the departure date (YES in step S252), the information transmission unit 236 transmits new route information indicating the route to the terminal device 1. This new route information includes information on the departure date and time for arriving at the destination during the departure date. This departure date / time is earlier than the departure time initially set by the user, but needs to be later than the current time.

  FIG. 5 is a diagram illustrating an example of a screen displayed on the display unit 122 when there is a route arriving at the destination during the departure date. This figure corresponds to step S115 in FIG. According to the new route information, if you depart from station A at 21:13 instead of 23:00 on October 10, 2011 and use trains P2 and Q2, It shows that the user can arrive at the destination station C. In this case, the transfer waiting time at station B is 30 minutes, which is shorter than in the case of FIG. The display unit 122 may further display information 51 indicating that it can arrive on the departure date.

  On the other hand, if the departure date and time for arriving at the destination during the departure date has passed the current time and cannot arrive during the departure date (NO in step S252 in FIG. 4), the departure date is initially set as the departure date. The next day, the departure time is changed to the time in time for the first train as the first train, and the route correction information generation unit 235 searches for the route (step S253). Then, the information transmission unit 236 transmits new route information indicating the obtained route to the terminal device 1.

  FIG. 6 is a diagram illustrating an example of a screen displayed on the display unit 122 when there is no route arriving at the destination during the departure date. According to the new route information, on the day after the initially set departure date, you can arrive at the destination C station as much as possible by using the first train P3, and the transfer waiting time at the B station It can be as short as 30 minutes. The display unit 122 may further display information 52 indicating that it cannot arrive during the departure date.

  As described above, when the departure date and time is set as the search condition, the route correction process is performed with a simple operation by simply selecting the information 50 in FIG. Next, the case where arrival date and time is set instead of departure date and time will be described.

  When the arrival date and time is set, it is considered that the user wants to reach the destination by the arrival date and time as much as possible. Therefore, the route search system presents the route to the user if there is a route that can arrive at the destination on the day before the arrival date as follows, and if the route cannot be arrived, leaves the arrival date as soon as possible. Present the route to arrive at.

  FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 122 when the arrival date and time is set and the route information for changing over the last train is obtained. This figure corresponds to step S108 of FIG. 2, and is obtained by performing a route search with the departure point set at A station, the destination set at C station, and the arrival date and time set at 08:30 on October 10, 2011. Route information is illustrated. According to this route information, the transfer waiting time is very long at 6 hours 58 minutes in order to use the first train Q4 when transferring at station B. Therefore, in addition to the route information, the display unit 122 also displays information 53 indicating that the route is inappropriate and prompts the search for the route.

  When the user selects the information 50 via the operation input unit 121 (YES in step S109 in FIG. 2), a route correction request, in this case, a request for searching for a route arriving on the day before the arrival date is received by the terminal device 1. To the server 2 (step S110). In response to this route correction request, the server 2 performs the following route correction processing.

  FIG. 8 is a flowchart illustrating an example of a route correction process when the departure date and time is set in the search condition. First, the route correction information generation unit 235 re-searches for a route that arrives at the destination on the day before the arrival date regardless of the set arrival date and time (step S261). For this purpose, for example, the route correction information generation unit 235 searches for the route that arrives at the latest destination the day before the departure date.

  If there is a route arriving within the day before the arrival date (YES in step S262), the information transmitting unit 236 transmits new route information indicating the route to the terminal device 1. The new route information includes departure date information and arrival date information for arriving at the destination on the day before the arrival date. This departure date needs to be later than the current time.

  FIG. 9 is a diagram illustrating an example of a screen displayed on the display unit 122 when there is a route arriving at the destination on the day before the arrival date. This figure corresponds to step S115 in FIG. According to the new route information, if you leave the departure station A at 21:13 on October 10, 2011 and use trains P5 and Q5, you will be at your destination the day before the arrival date. It shows that you can arrive at station C. In this case, the transfer waiting time at station B is 30 minutes, which is shorter than in the case of FIG. The display unit 122 may further display information 54 indicating that the user can arrive within the day before the arrival date.

  On the other hand, if the departure date and time for arriving at the destination within the day before the arrival date has passed the current time and cannot arrive within the day before the arrival date (NO in step S262), the departure date is set to the next day, and the departure time is set to the next day. The route correction information generation unit 235 searches for a route by changing the time to be in time for the first train as the first train (step S263). Then, the information transmission unit 236 transmits new route information indicating the obtained route to the terminal device 1.

  FIG. 10 is a diagram illustrating an example of a screen displayed on the display unit 122 when there is no route to reach the destination during the day before the arrival date. According to the new route information, by using the train P6 which is the first departure date, it is not possible to arrive at the destination station C at the arrival date and time that was initially set, but as soon as possible after departure on the arrival date You can arrive at station C and the transfer waiting time at station B can be shortened to 30 minutes. The display unit 122 may further display information 55 indicating that it cannot arrive the day before the arrival date.

  As described above, in the present embodiment, it is determined whether or not a route satisfying the search condition is appropriate based on the transfer waiting time, and when it is not appropriate, route correction processing is performed. Therefore, the user can easily acquire appropriate route information that does not use the first train across the last train without resetting the search conditions.

  In the above-described embodiment, an example of using a train has been shown, but a bus, an airplane, a ship, or the like may be used as a transportation means. The transportation means to be used may be the same kind of transportation means or different kinds of transportation means such as trains and buses. Furthermore, although an example of searching for a route between stations has been shown, the route search system may comprehensively search for a route including a walking section from an arbitrary departure point to a destination.

In addition, an example has been shown in which it is determined whether or not to use the first train based on the transfer waiting time, and it is determined that the route is inappropriate when using the first train. Alternatively, if the transfer waiting time is long, it may be determined that the route is inappropriate. This is effective when searching for routes in regions where the frequency of transportation is low. On the other hand, if it is determined that the route is inappropriate only when the first train is used, in addition to the transfer waiting time, the transfer waiting time is set at a predetermined time, for example, 3:00 am when the transportation system is not normally operated. Whether or not to straddle may be considered.
Alternatively, if the route network information includes a first departure flag indicating that it is a first departure, it may be determined whether to use the first departure in consideration of this.

  Further, FIG. 2 is an example of the processing operation of the route search system, and may be changed as appropriate. For example, when steps S206 to S211 are omitted and it is determined that the route is inappropriate, the route correction process may be automatically performed without waiting for the route correction request. Alternatively, from the server 2 to the terminal, information that prompts to re-search for an appropriate route, such as information itself indicating that the route is inappropriate, or information 50 in FIG. 3 and information 53 in FIG. You may transmit to the apparatus 1. In addition, when a departure time is set as a route correction request, the user can select whether to search again for a route that arrives during the departure date or to search again for a route that leaves on the next day. Good. Similarly, when the arrival time is set, the user may be able to select whether to search again for a route that arrives during the day before the arrival date or to search again for a route that leaves on the next day.

The configuration in FIG. 1 is an example, and at least a part of the configuration requirements in the server 2 may be in the terminal device 1. Conversely, at least a part of the configuration requirements in the terminal device 1 is in the server 2. May be. For example, the storage unit 22 and the control unit 23 in the server 2 may be provided in the terminal device 1 to configure a route search device that can search for a route only by the terminal device 1 without performing communication.
In this case, the search request transmission unit 124, the search request reception unit 232, and the like may be omitted as appropriate according to the configuration. Further, the server 2 may be configured using a plurality of devices. For example, only the storage unit 22 may be provided in a separate device.

  At least a part of the route search system described in the above-described embodiment may be configured by hardware or software. When configured by software, a program for realizing at least a part of the functions of the route search system may be stored in a recording medium such as a flexible disk or a CD-ROM, and read and executed by a computer. The recording medium is not limited to a removable medium such as a magnetic disk or an optical disk, but may be a fixed recording medium such as a hard disk device or a memory.

  Further, a program that realizes at least a part of the functions of the route search system may be distributed via a communication line (including wireless communication) such as the Internet. Further, the program may be distributed in a state where the program is encrypted, modulated or compressed, and stored in a recording medium via a wired line such as the Internet or a wireless line.

  Based on the above description, those skilled in the art may be able to conceive additional effects and various modifications of the present invention, but the aspects of the present invention are not limited to the individual embodiments described above. Absent. Various additions, modifications, and partial deletions can be made without departing from the concept and spirit of the present invention derived from the contents defined in the claims and equivalents thereof.
