To ensure the efficient and safe traffic order, as well as setting a series of traffic rules must pass a certain technological means to achieve them. Based on the current traffic control based on indepth analysis to, using the sensor detection technology, wireless transmission technology, realtime adjustment of the realization of the intelligent control technology, the sensor detection, realtime adjustment of traffic time algorithm bined with single chip microputer, is proposed based on single chip microputer intelligent traffic control system design.8051 single chip wireless intelligent traffic light control system controlled by 8051, traffic light display, LED countdown. Traffic detection and adjustment, such as wireless transmission module. In addition to the basic function of traffic light also has the traffic detection system, wireless transmission in order to achieve the purpose of the intelligent traffic control. System by the number of the test vehicle, by wireless transmissio
