This paper combines the fuzzy control technology with Charge Coupled Device (CCD) camera sensor technology to solve the defect of the existing traffic signal control method. CCD camera sensor technology can be real-time to receive traffic information, each intersection traffic conditions, the length of the traffic flow, traffic speed, and then through the signal processor calculates the time needed for traffic through the intersection at the moment, transfer to the fuzzy controller. At this point, the traffic situation of the other road also reached the fuzzy controller in real time. The fuzzy controller decides which intersection should continue to pass, and finally realize the traffic signal optimization control.
