With the accelerated pace of urbanization, the increasing popularity of the vehicle, people are more and more traffic congestion problems. The urban road traffic congestion has many causes: Vehicles, less road; the road is unreasonable; some drivers and pedestrians jaywalking; intersection traffic light time setting unreasonable. At present, Chinas urban street intersection traffic lights though is automatic, but a closer look reveals alternating traffic lights are timed type conversion, conversion interval that is fixed, Another less traffic light control system functions, lack of flexibility. In this thesis, the traffic lights at the crossroads of traditional optimization to be studied. The system uses 51 microcontroller as control core. System control red, green, yellow in time sequentially transform, and has the function to adjust the time. In addition the system has access function in emergency situations, traffic lights troubleshooting, or you can save the settings to recover after a power failure. The system has a certain innovation, practicality and reliability.
