(Processing-Navigation processing)
Next, navigation processing executed by the navigation system 1 configured as described above will be described. 2 and 3 are flowcharts of the navigation process (steps are abbreviated as “S” in the description of each process below). This navigation processing is started when, for example, the terminal device 2 is turned on and an instruction input for performing route guidance using the terminal device 2 is received by the operation unit 22.

  After the navigation process is started, the route search unit 24a waits until a destination is set via the operation unit 22 (SA1, No). When the destination is set via the operation unit 22 (SA1, Yes), the route search unit 24a searches for the moving route of the moving body from the departure point to the destination set in SA1 (SA2). Here, as the departure point, for example, the current position of the moving body detected by the current position detection processing unit 21 or the departure point set via the operation unit 22 can be used. The route search unit 24a performs a route search using a known route search method such as the Dijkstra method based on the map information acquired from the map information DB 32a of the center device 3 via the communication unit 20.

  Subsequently, the route search unit 24a determines whether the destination set in SA1 is a train station (SA3). For example, the route search unit 24a uses SA1 when the destination is set using the train station name or when the set location coordinates of the destination are within a predetermined distance from the position coordinates of the train station. It is determined that the set destination is a train station.

  As a result, when the destination set in SA1 is a train station (SA3, Yes), the train position specifying unit 24b acquires train operation information (SA4). For example, the train location specifying unit 24b obtains timetable information of a station (hereinafter referred to as “boarding station” as necessary) set as a destination in SA1 via a network from a railway company or a transfer search service server, Based on the timetable information, a message that prompts the user to select a train that the user wants to ride is displayed on the display 23. When the user selects a train that the user wants to ride via the operation unit 22, the train position specifying unit 24b starts from each station including the boarding station of the selected train (hereinafter referred to as “the train that the user wants to ride”). The operation information including the departure time, the delay time, the departure time of the preceding train and the succeeding train of the selected train, and the like are acquired from a railway company or a server for a transfer search service via a network (not shown). In addition, about the train which a user wants to ride, the train which a user wants to ride may be automatically determined based on the estimated required time to the boarding station and the current time. Further, the delay time of the train that the user wants to ride may be obtained from a SNS (Social Networking Service) server or the like.

  Subsequently, the train position specifying unit 24b determines whether the train that the user wants to ride is delayed by 10 minutes or more based on the operation information acquired in SA4 (SA5). As a result, when the train that the user wants to ride is delayed by 10 minutes or more based on the operation information acquired in SA4 (SA5, Yes), the user is likely to be able to board the preceding train of the train. The train to be ridden is reset to the preceding train (SA6).

  In SA5, when the train that the user wants to ride is not delayed for more than 10 minutes based on the operation information acquired in SA4 (SA5, No), or after the processing of SA6, the train position specifying unit 24b The current position is specified, and the display control unit 24e displays the specified position on the display 23 (SA7). Specifically, the train position specifying unit 24b includes a time Ta at which a train that the user wants to ride from a station immediately preceding the boarding station, a time Tb at which a train that the user wants to ride from the boarding station, and a current time Tn, Based on the delay time Td and the distance Z from the station immediately before the boarding station to the boarding station, the distance X that the train that the user wants to travel from the station immediately before the boarding station is expressed as X = Z × (Tn− It is calculated as Ta-Td) / (Tb-Ta). FIG. 4 is a diagram illustrating a display 23 that displays a current position of a train that the user wants to ride. As shown in FIG. 4, the display control unit 24 e causes the display 23 to roughly display the position of the train that the user wants to ride based on the distance X that the train that the user wants to travel from the station immediately preceding the boarding station. . This makes it possible for the user to easily grasp which region the train he / she wants to ride is currently traveling on.

  Returning to FIG. 2, after the process of SA7, the congestion status specifying unit 24d specifies the congestion status of the boarding station (SA8). Specifically, the congestion status specifying unit 24d receives information for specifying the congestion status of the boarding station via a network (not shown), a server of a railway company or a transfer search service, or a server of an SNS (Social Networking Service). Etc.

  Next, the position calculating unit 24c refers to the data recording unit 25 and specifies the past moving speed V of the moving object (SA9). When a plurality of users share one terminal device 2, for example, a past movement speed V is recorded in advance for each user, and a user who is using the terminal device 2 based on a user ID or the like ( That is, the moving speed V corresponding to the user may be specified by specifying the moving object). Then, the position calculating unit 24c specifies the current position of the train that the user specified by the train position specifying unit 24b in SA7, the congestion status of the boarding station specified by the congestion status specifying unit 24d in SA8, and specified in SA9. Based on the moving speed V of the moving body, the current position on the moving path that the moving body should reach in order for the moving body to arrive at the boarding station by the time the train that the user wants to ride departs from the boarding station (Hereafter, “position in time for the train you want to ride” is calculated if necessary) (SA10). First, the position calculation unit 24c calculates the time Tr until the train that the user wants to ride from the boarding station is Tr = Tb−Tn + Td. Next, the position calculation unit 24c calculates the distance P on the moving route from the position in time for the train to be boarded to the boarding station as P = V × Tr = V × (Tb−Tn + Td). Further, when it is determined in SA8 that the boarding station is congested by the congestion status specifying unit 24d, the time required for the user to move within the boarding station is increased compared to the case where the boarding station is not congested. The position calculation unit 24c subtracts a predetermined distance (for example, 30 m) from the distance P calculated as described above, since it is considered that the position in time for the train to be on is close to the boarding station. Thereby, the position which is in time for the train to ride is calculated.

  Subsequently, the position calculation unit 24c causes the current position detection processing unit 21 to specify the current position of the moving object (SA11). Proceeding to FIG. 3, the position calculation unit 24c determines the train that the user wants to ride based on the position in time for the train that the user wants to ride calculated in SA10 and the current position of the moving body specified by the current position detection processing unit 21 in SA11. It is determined whether guidance is given for the following train. Specifically, the position calculation unit 24c determines that the distance P on the movement route from the position in time for the train to be calculated calculated in SA10 to the boarding station is the distance Q on the movement route from the current position of the moving object to the boarding station. It is determined whether or not it is greater than 1/2 of (SA12).

  As a result, the distance P on the moving route from the position in time for the train to be boarded calculated in SA10 to the boarding station is not larger than ½ of the distance Q on the moving route from the current position of the moving body to the boarding station ( If it is less than 1/2) (SA12, No), the current position of the user is greatly delayed from the position in time for the train you want to ride, and even if the user runs, it is considered that the possibility of being in time for the train you want to ride is low Therefore, the position calculation unit 24c determines that guidance is provided for the subsequent train of the train that the user wants to ride, and resets the train that the user wants to ride to the subsequent train (SA13). Thereafter, the control unit 24 returns to SA4. In this case, the train position specifying unit 24b includes the operation information including the departure time from each station including the boarding station of the train that the reset user wants to ride, the delay time, the departure time of the preceding train and the subsequent train of the train, The information is acquired from a railway company or a transfer search service server via a network (not shown). Thereafter, the distance P on the moving route from the position in time for the train to be boarded calculated in SA10 to the boarding station is larger than ½ of the distance Q on the moving route from the current position of the moving body to the boarding station (SA12, The process from SA4 to SA13 is repeated until it is determined Yes.

  On the other hand, when the distance P on the moving route from the position in time for the train to be boarded calculated in SA10 to the boarding station is larger than ½ of the distance Q on the moving route from the current position of the moving body to the boarding station (SA12). Yes), since the current position of the user is not significantly delayed from the position in time for the train that the user wants to ride, and the possibility that the user will be in time for the train that he wants to ride is high, It is determined that guidance is not necessary. In this case, the position calculating unit 24c has a value obtained by subtracting the distance P on the moving path from the position in time for the train to be boarded to the boarding station from the distance Q on the moving path from the current position of the moving body to the boarding station. It is determined whether the distance is less than the first distance (30 m in FIG. 3) (SA14).

  As a result, the value obtained by subtracting the distance P on the moving route from the position in time for the train to be boarded to the boarding station from the distance Q on the moving route from the current position of the moving body to the boarding station is less than the first distance. If there is no (greater than or equal to the first distance) (SA14, No), the position calculation unit 24c determines the boarding station from the position in time for the train that you want to ride from the distance Q on the moving route from the current position of the moving body to the boarding station. It is determined whether or not the value obtained by subtracting the distance P on the moving route is less than the second distance (50 m in FIG. 3) longer than the first distance (SA15).

  As a result, the value obtained by subtracting the distance P on the moving path from the position in time for the train to be boarded to the boarding station from the distance Q on the moving path from the current position of the moving body to the boarding station is less than the second distance. In some cases (SA15, Yes), that is, in FIG. 3, when QP is 30 m or more and less than 50 m, it is considered that if the user walks quickly, there is a high possibility that the user will be in time for the train he wants to ride. Causes the display 23 to display a message to recommend fast walking (SA16).

  On the other hand, the value obtained by subtracting the distance P on the moving route from the position in time for the train to be boarded to the boarding station from the distance Q on the moving route from the current position of the moving body to the boarding station is not less than the second distance. In the case of (more than the second distance) (SA15, No), that is, in FIG. 3, when QP is 50 m or more, it is considered that there is a high possibility that the train will not be in time if the user does not run. The display control unit 24e displays a message on the display 23 to recommend running (SA17).

  The value obtained by subtracting the distance P on the moving path from the position in time for the train to be boarded to the boarding station from the distance Q on the moving path from the current position of the moving body to the boarding station is less than the first distance. In the case (SA14, Yes), that is, when QP is less than 30 m in FIG. 3, it is considered that if the user temporarily walks quickly, there is a high possibility that the train will be in time, so the display control unit 24e Does not display a message on the display 23 in particular.

  When the value obtained by subtracting the distance P on the moving path from the position in time for the train to be boarded to the boarding station from the distance Q on the moving path from the current position of the moving body to the boarding station is less than the first distance ( After the processing of SA14, Yes), or SA16 or SA17, the display control unit 24e causes the display 23 to display a position in time for the train to be ridden calculated by the position calculation unit 24c in SA10 (SA18). At this time, the display control unit 24e causes the display 23 to display the current position of the train to be ridden specified by the train position specifying unit 24b in SA7 together with the position in time for the train to be ridden calculated by the position calculation unit 24c in SA10.

  FIG. 5 is a diagram exemplifying a display 23 that displays a position in time for a train to be boarded and a current position of the train to be boarded. As shown in FIG. 5, the display control unit 24e displays a map screen on the display 23, and superimposes and displays a position in time for the train to be ridden on the map screen. Moreover, the display similar to the schematic display of the position of the train which the user illustrated in FIG. 4 wants to ride is displayed in parallel on the map screen.

  Returning to FIG. 3, after the process of SA18, the display control unit 24e causes the display 23 to display the moving path of the moving body to the boarding station and the current position of the moving body specified in SA11 (SA19). In the example of FIG. 5, the moving path of the moving body to the boarding station and the current position of the moving body are displayed superimposed on the map screen. As a result, the user can easily grasp the relationship between the current position of the moving body and the position in time for the train he / she wants to ride, and it is easy to see how late or in time the user is behind the train he / she wants to ride A guide that can be grasped can be provided. In addition, since the schematic display of the position of the train that the user wants to ride is also displayed, the user can intuitively grasp how close the train that the user wants to ride is to the boarding station.
