SYSTEM FOR LOCAL TRAFFIC CONTROL, PASSENGER INFORMATION AND TRAFFIC SIGNAL PRIORITY

SYSTEM FOER LOKAL TRAFIKLEDNING, TRAFIKANTINFORMATION OCH SIGNAL-PRIORITERING

In this report results from the research project "bus systems for large urban areas", Chalmers University of Technology, during the period 1974/75 regarding advanced traffic control are presented. Of special importance are the areas of measuring systems, local traffic control, passenger information, and traffic signal control with bus priority. A complex multicomputer system for advanced traffic control is outlined. Local traffic control (ltc) is realized by several regional subsystems. Every subsystem consists of one regional computer (rc) and many local computers/local controllers (lc). Ltc stands for an automatic detailed supervision of all buses in the system in order to make it possible to react fast and in an economic way when disturbances occur. Questions about the measuring system, data communications and computer systems are discussed. A fully equipped minicomputer (32k, disk-based operating system) can handle the tasks of an rc. The data communication speed needed is 3000 bps or less. The area of vehicle detectors is dealt with through a limited literature study. Traffic signal control with priority can be accomplished in many ways. The systems of today often use very rigid strategies. In this report some ideas of more flexible bus priority strategies are presented. (TRRL)
