  Specific embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram illustrating an example of a configuration of a taxi system 1 according to an embodiment of the present invention. The taxi system 1 includes a customer mobile terminal 10, a server (database) 100 disposed in a data center 20, a dispatch radio communication unit 31 disposed in a taxi company 30, and each of the taxi vehicles 40. And are connected so that they can communicate with each other.

  The server 100 disposed in the data center 20 manages the operation of taxi vehicles, and various taxi companies 30 and customers who use taxis own information useful for operating taxi vehicles. It has a function to be provided to the customer mobile terminal 10. The server 100 has a function of performing communication with the on-vehicle device (distribution wireless communication unit 41) mounted on the taxi vehicle 40 via the distribution wireless communication unit 31 and communication with the customer portable terminal 10, and has an estimated waiting time. It has a function of calculating and transmits the calculated estimated waiting time to the customer portable terminal 10. The predicted waiting time is a time predicted to be required from the time when the server 100 receives the dispatch request from the customer mobile terminal 10 to the arrival of the taxi vehicle 40 that can be used by the customer. The server 100 receives the position information of the customer mobile terminal 10 and the number of people waiting at the taxi stand received from the customer mobile terminal 10, and the position information and the operation state information of the taxi vehicle 40 received from the on-board unit (distribution wireless communication unit 41). , The estimated waiting time is calculated. The customer portable terminal 10 transmits the position information of the customer portable terminal 10 and the number of people waiting at the taxi stand as a dispatch request.

  The operation management of the taxi vehicle 40 performed by the server 100 includes dispatch to a plurality of taxi stands. The server 100 detects, for each of the plurality of taxi vehicles 40, one or a plurality of target taxi platforms that can be dispatched from the current position of each taxi vehicle 40, and predicts the arrival from the current position to each of the target taxi platforms. Calculate the time. The server 100 refers to the number of waiting persons at each of the target taxi ranks and the estimated arrival time to each of the target taxi ranks calculated for each of the plurality of taxi vehicles 40, received from the plurality of customer mobile terminals 10. Then, a taxi allocation instruction for allocating the taxi vehicle having the shortest predicted arrival time to the target taxi stand is created and transmitted to the taxi distribution wireless communication unit 31 of the taxi company 30.

  When the taxi vehicle 40 is renting to the destination, the server 100 determines a first predicted arrival time from the current position of the taxi vehicle 40 to the destination and a second predicted time from the destination to each of the plurality of target taxi platforms. The sum with the arrival time is calculated as the estimated arrival time. Further, when the server 100 receives from the customer mobile terminal 10 a location information history (movement history) in which the location information of the customer mobile terminal 10 is associated with the time information, the server 100 issues a dispatch instruction based on the received location information history. The predicted destination of the assigned taxi vehicle 40 is calculated, and the calculated predicted destination is transmitted to the taxi vehicle 40.

  In each taxi company 30 that manages the operation of taxis, a dispatch radio communication unit (such as an AVM: Automatic Vehicle Monitoring System) 31 connects to the server 100 via the Internet and acquires from the dispatch radio communication unit 41. The vehicle position information and the operating state are transmitted to the server 100, for example, periodically, and a dispatch instruction for each taxi vehicle 40 is received from the server 100. The dispatch radio communication unit 31 transmits the dispatch instruction received from the server 100 to each taxi vehicle 40.

  The customer mobile terminal 10 includes a wide-area wireless communication unit 11 that performs wide-area wireless communication with the server 100 in the data center 20, and a dedicated application 13 that is pre-installed taxi software. The wide area wireless communication unit 11 communicates with the server 100 via a mobile communication network (portable network) such as LTE (Long Term Evolution) or 4G (4th Generation). A user who intends to use a taxi can use the taxi waiting time prediction function by using the dedicated application 13 previously incorporated in the customer portable terminal 10 owned by the user.

  The dedicated application 13 receives an input of the number of people waiting at the taxi stand, and stores the current position information of the customer mobile terminal 10 acquired by the GPS (Global Positioning System) function and the number of people waiting by the user by the wide area wireless communication unit 11 as a server. Send to 100. Further, the dedicated application 13 receives the predicted waiting time transmitted from the server 100 by the wide-area wireless communication unit 11 and displays the received predicted waiting time on a screen. Further, the dedicated application 13 may transmit a position information history (movement history) in which the position information of the customer portable terminal 10 is associated with the time information to the server 100.

  The taxi vehicle 40 is equipped with a navigation system 43, a taxi meter 44, and a vehicle allocation wireless communication unit 41 as a vehicle-mounted device. The navigation system 43 has a function equivalent to that of a general on-vehicle device for car navigation, and acquires the position information of the taxi vehicle 40. Further, the navigation system 43 has a function of cooperating with the taxi meter 44. The taxi meter 44 grasps and manages the current operation state of the taxi vehicle 40 in a state such as "vacant", "pay", "pay", and the like. When the driver operates various buttons (not shown) provided on the taxi meter 44, the state of the taxi meter 44, such as "vacant car", "pay", "pay", etc., is changed. Transition. For example, when a new user gets on the taxi vehicle 40 in the “empty” state and the driver presses the “running button”, the taxi meter 44 transitions from the “empty” state to the “running” state.

  The dispatch radio communication unit 41 transmits the vehicle position information acquired from the navigation system 43 and the operation status information indicating the operation status of the taxi vehicle 40 acquired from the taxi meter 44 to the taxi company 30 using the dispatch radio communication. It transmits to the allocation radio communication unit 31 and receives an allocation instruction from the allocation radio communication unit 31. Instead of the navigation system 43, a part of the functions may be built in the taxi meter 44, a drive recorder, a digital tachometer, or the like.

  FIG. 2 is a diagram showing a flow of processing in the customer portable terminal 10. A user who intends to use a taxi at a taxi stand uses the dedicated application 13 of the customer mobile terminal 10 to input the number of people waiting for a taxi (step S1). FIG. 3 is a diagram illustrating an example of a screen display on the customer mobile terminal 10. As shown in FIG. 3, an operation screen is displayed on the touch panel 12 of the customer mobile terminal 10 by the dedicated application 13. On the touch panel 12, a current location field 51, a waiting number field 52, a transmission button 53, and a waiting time display field 54 are displayed. The current location column 51 displays the current location address of the customer mobile terminal 10. The waiting number column 52 displays the number of waiting persons input by a user operation. When the user operates the transmission button 53, the dedicated application 13 transmits the position information of the customer mobile terminal 10 and the input waiting number to the server (database) 100 in the data center 20 (step S2). The customer portable terminal 10 receives the estimated waiting time transmitted from the server (database) 100 by the wide area wireless communication unit 11, and displays the waiting time in the waiting time display field 54 of the touch panel 12 by the dedicated application 13 (step S3). , And the process ends.

  FIG. 4 is a diagram showing a flow of processing performed by the server 100 in the data center 20 to calculate predicted times to a plurality of taxi stands. The server 100 obtains the operation status and the position information of the taxi vehicle S from the vehicle allocation wireless communication unit 41 via the vehicle allocation wireless communication unit 31 among the plurality of taxi vehicles 40 managed by the taxi company 30 (step). S11). The server 100 detects, from the obtained current position G of the taxi vehicle S, one or a plurality of taxi stands N1, N2,... Nm that can be dispatched (step S12).

  Next, the server 100 determines whether or not the taxi vehicle S is renting to the destination based on the acquired operation status information of the taxi vehicle S (step S13). If the vehicle is renting (YES in step S13), the server 100 first calculates a predicted time T (first predicted arrival time) from the current position G of the taxi vehicle S to the destination M (step S14). Next, the server 100 sets n = 0 (Step S15), sets n = n + 1 (Step S16), and calculates a predicted time Tn (second predicted arrival time) from the destination M to the taxi stand Nn. I do. Then, the server 100 calculates a predicted time Ttn = T + Tn (Ttn: predicted arrival time) from the current position G of the taxi vehicle S to the taxi stand Nn, and stores the calculated time in a database in the server 100 (step S18). Thereafter, the server 100 determines whether or not n is smaller than m (step S19). If NO, the process ends. If YES, the process returns to step S16 to repeat the processes from steps S16 to S18.

  In step S13, if the taxi vehicle S is not renting (NO in step S13), the server 100 sets n = 0 (step S20), sets n = n + 1 (step S21), and sets The estimated time Ttn = Tn from the current position G to the taxi stand Nn is calculated and stored in the database (step S22). Then, the server 100 determines whether or not n is smaller than m (step S23), terminates the process if NO, returns to step S21 to repeat the processes of steps S21 and S22 if YES. Through the above processing, the server 100 calculates the estimated arrival times from the current position G of the taxi vehicle S to one or more taxi stands, and stores the calculated arrival times in the database.

  FIG. 5 is a diagram showing a flow of the process of dispatching the vehicle 100 to a plurality of taxi stands a to c by the server 100. The server 100 stores the customer position information transmitted from the plurality of customer mobile terminals 10 and the number of waiting persons at each taxi stand a to c, and the vehicle position information and operation state information of all the taxi vehicles 40 managed and operated by the taxi company 30. Based on this, a landing list with waiting persons (the number of waiting taxis is 1 or more) is generated, and the taxi vehicle Sn and the corresponding landing where the predicted arrival time is the shortest in all the taxi vehicles 40 are extracted (step S31). The server 100 determines whether the corresponding landing is the landing a (step S32). If it is the landing a (YES in step S32), the server 100 creates and transmits a dispatch instruction for allocating the taxi vehicle Sn to the landing a (step S33), and subtracts 1 from the dispatch waiting person Ha at the landing a (step S33). S34). Then, the server 100 determines whether or not the number of people waiting to be dispatched Ha is greater than 0 (step S35). If YES, the process returns to the step S31, and if NO, the process proceeds to a step S36. In step S36, the server 100 excludes the hall a from the hall waiting list, and proceeds to the processing of step S46 described below. When returning to the process of step S31, the process is repeated after the taxi vehicle 40 assigned in step S33 is excluded from all the taxi vehicles 40. In steps S40, S44, and S46, which will be described later, the processing is repeated after the taxi vehicle 40 assigned in the same manner is excluded.

  If the corresponding landing is not the landing a in step S32 (NO in step S32), the server 100 determines whether the corresponding landing is the landing b (step S37). When the corresponding landing is the landing B (YES in step S37), the server 100 instructs to allocate the taxi vehicle Sn to the landing b (step S38), and subtracts 1 from the waiting queue number Hb of the landing b (step S38). Step S39). Then, the server 100 determines whether or not the number of people waiting for dispatch Hb is greater than 0 (step S40). If YES, the process returns to the step S31, and if NO, the process proceeds to a step S41. In step S41, the server 100 excludes the hall b from the hall waiting list, and proceeds to the processing of step S46 described below.

  If the corresponding landing is not the landing b in step S37 (NO in step S37), the server 100 issues a dispatch instruction to allocate the taxi vehicle Sn to the landing c (step S42), and subtracts 1 from the waiting queue number Hc at the landing c. Subtraction is performed (step S43). Then, the server 100 determines whether or not the number of people waiting for dispatch Hc is greater than 0 (Step S44). If YES, the process returns to Step S31. If NO, the process proceeds to Step S45. In step S45, the server 100 removes the hall c from the hall waiting list, and proceeds to the process of step S46 described below.

  In step S46, the server 100 determines whether or not the sum of the waiting queues Ha, Hb, and Hc at all the landings a, b, and c is greater than 0. If YES, the process returns to step S31. If so, the process ends.

  FIG. 6 is a diagram illustrating an example of allocation of vehicles to a plurality of taxi stands a, b, and c by the server 100. First, the server 100 extracts the vehicle B and the landing a having the shortest predicted arrival time (2 minutes) among all the taxi vehicles A to E from the waiting list with waiting person shown in FIG. 6A. The server 100 instructs the vehicle allocation to allocate the vehicle B to the landing a, and subtracts 1 from the three waiting queues at the landing a (FIG. 6B).

  Next, the server 100 issues a dispatch instruction to allocate the vehicle E having the shortest predicted arrival time (3 minutes) among the vehicles A and the vehicles C to E that have not been dispatched to the landing a, and One is subtracted from the two (FIG. 6 (c)). Next, the server 100 issues a dispatch instruction to allocate the vehicle A having the shortest predicted arrival time (6 minutes) among the vehicles A, C, and D that have not been dispatched to the landing b, and One is subtracted from the two (FIG. 6 (d)). Next, the server 100 issues a dispatch instruction to allocate the vehicle D having the shortest predicted arrival time (10 minutes) among the vehicles C and D that have not been dispatched to the landing c, and 1 is subtracted (FIG. 6E). Since the waiting queue number at the landing c has become 0, the landing c is excluded from the waiting place list.

  The server 100 distributes the vehicle C that has not been dispatched to the landing b among the landings a and b, which has a shorter predicted arrival time, and subtracts 1 from the waiting queue at the landing b (FIG. 6 (f)). Since the number of waiting vehicles at the landing b has become zero, the landing b is excluded from the waiting-list of waiting places. As described above, dispatch instructions are issued to all the vehicles A to E.

  As described above, according to the taxi system of the present embodiment, when a user who intends to use a taxi enters the number of waiting persons into the customer portable terminal 10 and transmits it to the server 100 in the data center 20 at the taxi stand, the server Since the accurate predicted waiting time calculated at 100 is transmitted to the customer portable terminal 10 and displayed, the user can confirm the accurate predicted waiting time without installing a special facility at the taxi stand. In particular, by calculating the "time to the destination currently rented" and "forwarding time from the destination to the taxi stand" of each taxi vehicle, the waiting time of the taxi vehicle currently renting is accurately predicted. it can. For this reason, it is possible to predict the waiting time in accordance with the actual operation situation. In addition, when the number of waiting persons is input on the customer portable terminal 10, by counting one group of a plurality of persons who can board one taxi vehicle 40 as one person, it is possible to more accurately predict the waiting time.

  It should be noted that the above-described waiting time prediction may be combined with the destination prediction to be used at the time of vehicle allocation. FIG. 7 is a diagram illustrating a flow of the destination prediction process performed by the server 100. The server 100 receives the dispatch request from the customer portable terminal 10 (step S51), and stores a movement history (GPS information, position information history) in which the position information and the time information of the customer portable terminal 10 in the past month are associated with each other. It is acquired (step S52). The server 100 extracts a destination point from the current position of the customer portable terminal 10 from the acquired movement history (step S53). Next, the server 100 extracts, from the extracted destination points, points where the user stayed at the same point for at least one hour (step S54). Further, the server 100 counts the extracted stay points in descending order of the stay frequency (step S55), and sets the point with the highest stay frequency as the destination prediction point (step S56). As described above, the server 100 can predict a place (home, company, business partner, etc.) where each user is likely to go from the taxi stand, and can use the set destination prediction point for creating a dispatch instruction. Further, the server 100 may transmit the set destination prediction point to the dispatch radio communication unit 31 in the taxi company 30.
