【Abstract】: In recent years the urban traffic congestion phenomenon,

especially the drivers violate the traffic accident frequency, serious, vehicle exhaust pollution, introduce set computer, information, electronic and communication and many other new technologies in the integration of intelligent transportation command center control system. The system of the installation and use, greatly ease the urban road congestion phenomenon, improve the road capacity. To reduce the number of times the driver violations, restrain the traffic accident, and to reduce emissions from vehicles, so as to reduce the environment pollution have played an underestimate role 。.

Analysis of modern urban traffic control and management problems, based on the status of the urban and rural traffic to the actual situation of expounds the control system of the traffic lights work principle, this paper presents a simple and practical urban traffic control system hardware circuit design.
