Bus route and position display system controlling traffic lights - uses road-side detector beacons to obtain vehicle position and processes information to determine traffic signal switching

摘要

A display is provided in a central control station showing the position of each vehicle. This information is used to control traffic signals to facilitate the mobility of the vehicles. Detector beacons are placed along the route of the vehicles and transmit data on the passage of the vehicle via cables to a central control station, where a display panel indicates the vehicles positions. A link to the computer or operator controlling the switching of traffic signals then allows the signal duration to be altered to facilitate passage of the vehicles. The information provided by the bus includes the route and vehicle identification numbers and also the number of passengers.
