The operation of the operation example of the bus operation time management system will be described below. Before departure from the first stop, the bus driver inputs the name of the departure stop and the time of the departure using an input key provided in the driver's seat. Thereby, the identification ID of the bus is determined, and data communication with the bus stop on the route becomes possible. The bus navigation device always performs positioning using a GPS receiver, and transmits current position information to the bus stop display device using the data transmission / reception antenna 302. The bus stop display device is an antenna 30 for data transmission and reception.
Based on the data received in step 4, the own location information on the database prepared in advance is compared with the received current position data of the bus to calculate the expected bus arrival time, and the time display unit 3
The waiting time is notified to the bus passenger by displaying the message on the display 06 or outputting sound from the speaker 309.

Although the bus stop display device has a built-in clock for displaying the current time, the bus navigation device transmits and receives time information obtained as a result of positioning by the GPS receiver together with the current position information. By transmitting to the bus stop display device using the antenna 302 for bus, the bus stop display device can correct the time of its own clock based on the time information. The time display section 306 of the bus stop display device has a display item that allows the scheduled bus arrival time to be updated in addition to the standard operation timetable, and the display time is updated each time the estimated arrival time is updated. Is done. When the bus driver determines that it is impossible to arrive at the bus stop by the estimated time of arrival due to traffic jams, accidents, etc., the input key installed in the driver's seat sends the degree of traffic jam to the bus stop display device, and the bus stop display device , Traffic jam information can be incorporated as an element when calculating the estimated arrival time.

If there is a DGPS base station and a GPS reception antenna 303 in the bus stop display device, positioning is always performed by the DGPS base station, and position correction information is transmitted from the data transmission / reception antenna 304 to the bus navigation device. Data transmission / reception antenna 3
By receiving the position correction information using 02 and inputting it to the GPS receiver, the position accuracy of the own vehicle can be improved.

An information storage unit is provided in the bus stop display device, and can store the actual arrival time of the bus sequentially. The information display unit 307 can display the position of the bus stop and the current location of the bus on a route bus operation route map stored in the information storage unit in advance. By pressing the general input key 308, the bus user can select the content displayed on the information display unit 307, and can browse a map around the bus stop and information on facilities on the bus stop. In the above example, the map and facility information are displayed on the information display unit 3.
07, a message board function may be provided so that a bus user can freely write a message.

[0017]

In the bus operation time management system according to the present invention, the bus operation time can be managed by communication between only two persons, the bus navigation device and the bus stop display device, thereby simplifying the system. Cost reduction becomes possible. In addition, the accuracy of time information can be improved by using position information by GPS or incorporating traffic congestion information from a bus driver as an element when calculating the estimated arrival time as in the invention of claim 4. Further, as in the invention of the third aspect, a timetable capable of sequentially updating the estimated bus arrival time is mounted, and as in the invention of the eighth aspect, a map around the bus stop and a map on the map are displayed. As described in the embodiment, the information on a certain facility can be browsed, the message board function is installed, and the accuracy of the time information is improved as in the invention of claim 2 or 4, so that the bus is improved. The waiting time can be used effectively, and the convenience for bus users is greatly improved.

According to the fifth aspect of the present invention, by sequentially recording and storing daily bus arrival times, it is possible to collect reference data for revision of bus operation schedules. According to the invention of claim 6, the convenience of the system can be improved by setting the bus ID to the name of the departure stop and its departure time. According to the invention of claim 7, the DGPS base station is mounted in the bus stop display device, and the position correction information is transmitted from the bus stop display device to the bus navigation device.
