Simulation of Area Wide Real Time Traffic Control. Final Report.

摘要

The study was performed to develop the Area-Wide Real-Time Traffic Control (ARTC) System which uses real-time traffic flow information and design signal timing plans online. The ARTC system consists of microcontrollers at each intersection to perform signal timing computations which are connected to each other by a communication network. The signal controllers exchange traffic flow data to aid in the signal timing computations. A simulation of the ARTC system was performed and compared with a fixed time control which was computed using the TRANSYT7F program. Results of the simulation show significant savings in delay and stops by ARTC over fixed time control. Under the ARTC system, signal controllers must process large amounts of real-time traffic information and communicate with neighboring signal controllers while making traffic control decisions. A modification of the TYPE179 controllers to suit the needs of the ARTC system and future traffic management systems may be expensive and infeasible. A design of the signal controller using the microcontroller MC68332, which has the desired features for a typical signal controller, is also presented.
