【正文】 ractIn recent years the urban traffic, especially the driver crowding illegal serious incidents, vehicles, traffic problems such as exhaust pollution, this paper introduces set puter, information, electronic and munication etc many hightech means in the integration of intelligent transportation mand center control system. In the design of the system, the main use of PLC and sensor bination of methods, the automatic acquisition vehicle data, according to the corresponding traffic automatically increase or decrease the green duration of intelligent control. This system installation can greatly alleviate the urban road congestion phenomena, improve the road transportation capacity. Reduced the number of drivers violation, curbing the traffic accidents, and to reduce vehicle exhaust emission, reducing environmental pollution have played a cannot underestimate role. Analyzes modern urban traffic control and management problems, based on the status of the actual situation of urban traffic control system is described the working principle of lights, and puts forward a simple and practical urban traffic control system hardware circuit design.
