With reference to FIG. 4, a procedure from when a user requests bus 110 operation information to the bus location center 100 until the bus location center 100 provides bus 110 operation information to the user will be described.

  The user accesses the bus location center using a terminal connectable to the network (S100). Here, the terminal that can be connected to the network may be a portable terminal such as a mobile phone, a notebook personal computer, or a PDA (Personal Digital Assistance), or a computer that is fixed like a desktop personal computer. Good.

  When there is an access from the user's terminal, the bus location center 100 retrieves the bus route information from the management apparatus side operation route database 103 and transmits the route information to the user's terminal (S102). As shown in FIG. 5, in this embodiment, route information is provided to the user in the form of a route map 210, but the form of providing route information is not limited to this, and is provided to the user in text. May be.

  The user selects a stop to get on and a stop to get off based on the route information transmitted from the bus location center (S104). As shown in FIG. 5, the stop may allow the user to directly input the name of the stop into the stop route selection unit 220, or display the route map 210 on the screen and select from the route map 210. May be. Further, in this embodiment, the stop to get on and the stop to get off are selected or input, but only the stop to get on or only the stop to get off may be selected or input.

  When the user selects a bus stop and the route is fixed, the bus location center 100 determines that the bus location center 100 is within a predetermined range including the time when the bus stop is selected based on the bus schedule recorded in the bus schedule database 104 (for example, The presence / absence of a bus operating at 30 minutes before and after the time when the stop is selected is searched (S106). If the corresponding bus does not exist as a result of the search, the information is transmitted to the user terminal (S108). A message indicating that the corresponding bus does not exist is displayed on the information display unit 230 on the screen of the user terminal.

  If the corresponding bus exists in S106, the terminal ID of the in-vehicle device 120 mounted on the corresponding bus is output from the operation diagram database 104 (S110). When there are a plurality of corresponding buses, the terminal IDs of the in-vehicle devices mounted on all the corresponding buses are output from the operation diagram database 104.

  After S110, the control unit 101 of the bus location center 100 outputs a position data transmission instruction via the communication unit 123 to the in-vehicle device 120 having the output terminal ID (S112). After outputting the position data transmission instruction, the bus location center 100 waits for position information to be transmitted from the in-vehicle device 120.

  In the in-vehicle device 120, first, when the operation of the bus 110 is started, the route operated by the driver is selected by the route selection unit 122 (S114).

  When the operation of the bus 110 is started, the GPS receiving unit 125 receives a GPS signal from the GPS satellite 160, and acquires position information including the latitude and longitude of the current location at regular intervals (for example, at intervals of 5 seconds) (S116).

  The arrival determination unit 126 compares the position information acquired in S116 with the area information preliminarily recorded in the in-vehicle apparatus side operation route database 124 and regarded as the reference position of the route selected by the route selection unit 122. It is determined whether or not the vehicle arrives at a reference position such as a stop or an intersection (S118).

  When the arrival determination unit 126 determines in S118 that the arrival has arrived at the stop, the control unit 121 of the in-vehicle device 120 determines the position information and the reference position name (for example, stop name or intersection name) including the time, latitude, and longitude at the time of determination. Etc.) is recorded in the operation data recording unit 127 (S120). If the arrival determination unit 126 determines that it has not arrived at the stop, the process returns to S116.

  After S120, it is confirmed whether or not a position data transmission instruction is issued from the bus location center in S112 (S122).

  If it is determined in S122 that the position data transmission instruction has been issued, the in-vehicle device 120 uses the communication unit 123 to store the latest operation data recorded in the operation data recording unit 127 as a bus location. The data is transmitted to the center 100 (S124).

  When the communication unit 102 of the bus location center 100 receives the operation data, the control unit 101 records the received operation data in the vehicle position information recording unit 106. Based on the determination time and position information included in this operation data, the delay time from the regular schedule registered in the schedule diagram database 104 is calculated, and the regular arrival time at the stop designated by the user is calculated. The delay time is added to calculate the expected arrival time at the stop designated by the user (S126).

  The expected arrival time providing unit 107 transmits the operation information including the delay time from the regular schedule calculated in S126 and the expected arrival time to the stop to the requested terminal (S128). Here, when there are a plurality of buses operating within a predetermined time on the route requested from the terminal, the operation information regarding all the buses operating is transmitted.

  The operation information transmitted in S128 is displayed on the information display unit 230 of the terminal of the user who requested it, and the user can check the bus operation status (S130).

  When there is no position data transmission instruction from the bus location center 100 in S122 or when the transmission of operation data to the bus location center 100 is completed in S124, the stop registered in the operation data recording unit 127 is the end point. Whether or not (S132). If the stop registered in the operation data registration unit is not the end point, the process returns to S116 and the position information is acquired again. When the stop registered in the operation data registration unit is the end point, it is considered that the route has been completed, and the position information recording process in the in-vehicle device 120 is terminated.

  As described above, according to the present embodiment, the on-board device of the bus does not always transmit the position information to the bus location center, but is requested by the user when the user requests provision of bus operation information. The location information transmission instruction is requested only to the bus, and the location information is transmitted from the in-vehicle device of the bus to the bus location center only after receiving the request. It is possible to provide a vehicle operation management system that can greatly reduce the number of packets and greatly reduce the communication costs borne by the operating company.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above embodiment, the route information is transmitted from the bus location center 100 to the user's terminal and then the user selects a stop. However, the route information is held in the user's terminal in advance. Alternatively, a stop may be selected. By preserving the route information on the user's terminal in advance, the user can acquire the vehicle position information more quickly.

  Moreover, in the said embodiment, although the positional information which consists of the latitude and longitude of a present location is acquired at fixed intervals, a driver | operator may input positional information manually. For example, you may make it record the stop which passed to the present location measurement part at the timing which operated the in-vehicle broadcast of the vehicle, and the time which passed.

  In the above embodiment, in the arrival determination process of the arrival determination unit 126, the position information received from the GPS reception unit 125 and the area information registered in the operation route database are compared, but the determination is performed. The arrival determination unit 126 may perform the arrival determination process after determining the reference position for performing the arrival determination process in conjunction with the in-car broadcast of the vehicle.
