The urban traffic signal lights of the command and control system, automatic to traffic orderly. Urban traffic control system is designed for automatic command urban traffic control system is one of the most important parts of it. This paper discusses the traffic simulation based on AT89C51 control system, this system can according to actual situation through traffic outside the keyboard to increase or decrease traffic banned. Using LED digital display its corresponding pipe using light emitting diode, the actual situation of traffic simulation. According to the complex conditions, especially an environmental emergency module, improve the efficiency of the intersection traffic lights, further improve the control systems with practical, simple...
