Then, the meeting place presentation unit 233 refers to the meeting place data when searching for the meeting place, and if there is a meeting place that is frequently used by this group when the destination is the same as the current destination, the search is not performed. You may provide the meeting place to

5 and 6 are diagrams for explaining the search for a meeting place. For example, a case of destination T1 of user A and user B will be described as an example. In this case, the meeting place presentation unit 233 compares the user A's route Ra and the user B's route Rb. Then, the meeting place presentation unit 233 selects meeting place candidates so that the effort of all users (users A and B) is close to the destination T1 on the basis of required time and distance from the nearest station to the destination T1. Take out M1 to M5 ((1) in FIG. 5). In other words, the meeting place presentation unit 233 selects the meeting place candidates M1 to M5 of the places between the nearest station to the destination T1 and the destination T1 in order of the shortest required time and travel time for the user A and the user B. Extract.

At this time, the meeting place presentation unit 233 narrows down candidate meeting place locations using variables such as the weather, public transportation and road congestion, and the number of people ((2) in FIG. 5). The weighting of these variables can be changed by the user (eg, secretary). Then, the meeting place presentation unit 233 presents, for example, the meeting place candidate M1 having the closest required time and travel time between the user A and the user B as the meeting place (FIG. 6). Also, if it is raining at the time of the meeting, the meeting place presentation unit 233 may present an indoor meeting place (for example, the meeting place candidate M5 in FIG. 5). In addition, the meeting place presentation unit 233 may present a meeting place such as a square with a large space (for example, the meeting place candidate M4 in FIG. 5) when the number of people is large.

The route guidance unit 234 guides each terminal device 10 to the meeting place. Specifically, the route guidance unit 234 causes each terminal device 10 to display the position of the meeting place, the route from the user's position to the meeting place, the departure time, the departure and arrival times of each station of the transportation system to be used, and transfer information. .

The latecomer determination unit 235 determines whether or not there is a user who is late for the meeting place based on at least the position data of each terminal device 10 possessed by each user. The latecomer judging unit 235 is based on the position data of each terminal device 10 owned by each user, operation data including information such as delays and congestion of public transportation, road congestion status, and weather data. Determine whether or not there is a late user. For example, if a certain user misses the train to be used on the route guided by the server 20 and cannot arrive at the meeting place at the meeting time even if he/she gets on the next train, the latecomer determination unit 235 determines whether the user is late. It is determined that If there is a user who is late, the tardy determination unit 235 determines that there is a user who is late in the terminal device 10 of any user belonging to the group (for example, an organizer or a user who is scheduled to arrive at the meeting place first). to notify you.

The gathering place presentation unit 233, when requested to present a waiting place where other users wait while waiting for the late user, searches for a waiting place where the other users wait while waiting for the late user. . The meeting place presenting unit 233 is provided when the user who is late is waiting until the meeting place arrives, but when the arrival time of the destination is in time and a search for a waiting place is requested, or when the user who is late arrives at the meeting place. To search for a waiting place when the search for the waiting place is requested even if waiting until arrival will not arrive in time for the arrival time of the destination. The gathering place presenting unit 233 presents the retrieved waiting places to each terminal device 10 . The waiting place may be the same place as the meeting place, or may be a place different from the meeting place as described below.

For example, the meeting place presenting unit 233 refers to the weather data, and presents the waiting place in the basement or in the building to each user's terminal device 10 when it is raining at the meeting place. In addition, when the number of people waiting is large, the meeting place presenting unit 233 presents a place large enough for a large number of people to wait as a waiting place to the terminal device 10 of each user. On the other hand, when the number of people waiting is as small as 2 or 3 people, it is possible to wait even if the space is small. The gathering place presentation unit 233 searches for a waiting place using a neural network that has learned weather, number of people, combination examples of meeting places and waiting places, etc. as learning data.

In addition, the meeting place presentation unit 233 combines the destination, the waiting place, and the explanation of the place when the waiting place was presented to this group in the past (not getting wet in the rain, allowing a large number of people to wait, etc.). may be registered as waiting place data. Then, the gathering place presentation unit 233 refers to the waiting place data when searching for a waiting place. You may present the waiting place.

The gathering place presentation unit 233 searches for the meeting place and presents the found meeting place to each terminal device when the presentation of the meeting place of the other user and the late user is requested. For example, if the user who is late arrives at the gathering place, he or she will not be able to arrive at the destination in time, and if a presentation of the meeting place is requested, the meeting place of the other user and the user who is late is displayed. and presents the retrieved meeting place to each terminal device 10. - 特許庁In addition, if the user who is late arrives at the meeting place and is in time for the arrival time of the destination, and the presentation of the meeting place is requested, the meeting place of the user who is late and the other users is displayed. and presents the retrieved meeting place to each terminal device 10. - 特許庁

The position data acquiring unit 232 acquires the position data of each terminal device 10 of the user belonging to the group upon receiving a request for presentation of the dissolution location of the group from the terminal device 10 of the user belonging to the group.

The dissolution place presentation unit 236 calculates the route to the return home place of each user based on the position data of each terminal device 10 acquired by the position data acquisition unit 232 . Based on the calculated route, the dissolution place presentation unit 236 searches for any place in the overlapping part of the routes of all users as the dissolution place. Then, the dissolution place presenting unit 236 presents the retrieved dissolution place and the route to the return home place to each terminal device.

The route guidance unit 234 provides route guidance to each user's return home location on each terminal device 10, and if there is a user whose route overlaps, the route guidance unit 234 provides the terminal device 10 of the user whose route overlaps. Notify other users who will be traveling and the means of transportation they will be using. The route guidance unit 234 may give guidance to a route that partially overlaps among a plurality of users with priority over other routes so that users returning in the same direction can return home together halfway.

[Meeting place presentation processing]
Next, a processing procedure of the communication system according to this embodiment will be described. First, the processing procedure of the gathering place presentation processing for the terminal device 10 of the user will be described. FIG. 7 is a sequence diagram showing the procedure of the meeting place presentation process. 8 to 10 are diagrams showing examples of screens of the terminal device 10A.

As shown in FIG. 7, the user A who is the organizer operates the terminal device 10A and requests the server 20 to register the users A to D in the group (steps S1 and S2). Specifically, the user A activates a route guidance application provided by the server 20 of the terminal device 10A. For example, as shown in the screen DA1 of FIG. 8, user A selects each user to be registered in a group via a telephone directory, e-mail address, SNS, etc., and performs group registration as shown in frame W11. Then, the terminal device 10A requests group registration of users AD.

When the server 20 receives a group registration request from the terminal device 10A, the server 20 selects from the terminal devices 10A to 10B owned by the users A to D, respectively, the identification information of the terminal devices 10A to 10D, the return home location of each user, and the information selected by each user. User data such as a desired means of transportation is acquired (step S3), and the acquired data is registered in the group data 221 as data of the group G1 (step S4).

Subsequently, as shown in the screen DA1 of FIG. 8, the user A inputs the destination in the frame W12, inputs the arrival time in the frame W13, and selects the meeting place search button F1. As a result, the terminal device 10A receives the input of the destination and the arrival time (step S5), and transmits to the server 20 a request for presenting the meeting place of the group G1 registered by the user A together with the received destination and arrival time. (step S6).

The server 20 acquires the position data of the terminal devices 10A-10D of the users A-D belonging to the group G1 (steps S7 and S8). While the route guidance application provided by the server 20 is running on each of the terminal devices 10A to 10D, the server 20 continues to acquire position data from each of the terminal devices 10A to 10D.

The server 20 acquires traffic data including operation data of various public transportation facilities, usage data of various means of transportation, road conditions, etc., from the traffic data providing server 30 (step S9). The server 20 acquires the weather data of the location where the terminal devices 10A-10B are located and the weather data of the destination from the weather data providing server 40 (step S10).

Based on the position data of each terminal device 10 obtained by the position data obtaining unit 232, the group data 221, the arrival time of the destination, the traffic data 223, and the weather data 224, the server 20 determines the destination of each user AD. A route to is calculated (step S11).

Based on the calculated route, the server 20 searches for a meeting place where the burden of movement of each of the users A to D is similar among the users A to D (step S12). Then, the server 20 presents the searched meeting place to each terminal device 10 (steps S13 and S14).

The meeting place presented by the server 20 is displayed on each of the terminal devices 10A to 10D (steps S15-1 to S15-4). For example, on the terminal device 10A of the user A, as shown in the screen DA2 of FIG. , this meeting place M1 is displayed with a pin P1. Then, the user A selects the departure button F2 on the screen DA2, and a route guidance request from the terminal device 10A to the meeting place M1 is transmitted to the server 20. FIG.

When the terminal devices 10A to 10D transmit a request for route guidance to the meeting place (step S16), the server 20 refers to the position data of each terminal device 10A to 10D for each of the users A to D, and The terminal devices 10A to 10D provide route guidance to the meeting place (steps S17 and S18). For example, on the terminal device 10A of the user A, as shown in the screen DA3 of FIG. 10, the departure place and departure time are displayed, and the route R3 to the meeting place is displayed on the map. Note that the server 20 may control data transmission and data output in the terminal device 10A of the user who is the organizer so that the movement status of each user in the group can be checked.

[Latecomer judgment processing]
FIG. 11 is a sequence diagram showing the processing procedure of latecomer determination processing for the meeting place. FIG. 12 is a diagram showing an example of the screen of the terminal device 10A.

The server 20 guides the terminal devices 10A to 10D to the meeting place (step S21), and at least determines whether users who are late (latecomers) are late based on the location data of the terminal devices 10A to 10D possessed by each user. It is determined whether or not there is (step S22). When it is determined that there is a person who is late (step S22: Yes), the server 20 notifies the terminal device 10A of user A who is the manager of the group that there is a user who is late (step S23). In response to this notification, the terminal device 10A displays the fact that there is a latecomer (see frame W31 in FIG. 12), the name of the latecomer, and the location of the latecomer, as shown in the screen DA4 of FIG. A pin P41 indicating the position of is displayed. The server 20 may further notify the terminal device 10 of the expected time of arrival at the meeting place.

Subsequently, the server 20 determines whether or not the latecomers will arrive at the destination in time even if they wait until they arrive at the meeting place (step S24). This determination may be made by the server 20 based on the position of each user, the position of the destination, the position of the meeting place, traffic data, weather data, and the like. Further, the server 20 may perform the determination process of step S24 according to the content of the notification transmitted from the terminal device 10A of the user A who is the organizer. The server 20 waits for the latecomers, whether they will arrive at the destination on time (step S24: Yes) or not in time (step S24: No) even if they wait until they arrive at the meeting place. is received from the terminal device 10 (steps S25 and S26).

For example, as shown in FIG. 12, the user A refers to the screen DA4 and confirms the name of the latecomer, the location of the latecomer indicated by the pin P41, and the arrival time of the latecomer at the meeting place.
