Due to the current intersection signal control is mainly controlled by the traditional way, most do not have intelligence, it's difficult to achieve on the random change of traffic control effectively. In order to solve the problem, this paper from two aspects of the fuzzy control and adaptive control starts to study the problem, and analyzes its simulation, the results show that, the adaptive control system is better than the control effect of fuzzy control and traditional control system. At last, it extends single intersection to the multi-intersection traffic signal control.
