Abstract: PURPOSE: A control system is provided to achieve an improved effectiveness and safety in operation of bus by allowing radio communication among bus, central control computer, and bus station. CONSTITUTION: A radio data transmitting/receiving system is mounted to a central control computer installed at a central management office, so that bus operation information is collected from a traffic information collector installed at a city bus and a position information generator installed at a bus station. In addition, the radio data transmitting/receiving system sends data needed for bus operation to the traffic information collector and position information generator. Such a data transmission/receiving is performed between the traffic information collector and the position information generator. The central control computer creates a database for the operation information collected from the traffic information collector and the position information generator, and outputs the processed information onto a monitor or a printer. The position information generator transmits bus station information and passed time of the previous bus, informing passengers staying at the bus station of expected arrival time for bus, and control communication protocol. The traffic information collector collects position information and passed time of the previous bus, reports the collected passed time to the position information generator, sensed running speed from an encoder, receives command from the central control computer, and informing the passengers of the position of bus station.
