Study on practical fuzzy control system of traffic signal
一种实用的交通信号模糊控制系统的研究

A fuzzy control system structure for an urban junction was proposed.The traffic flow in the next cycle was estimated,and the maximum time of green light was adjusted dynamically.The fuzzy controller was responsible for controlling the length of the green time.A simulation experiment was carried out to measure the capability of above fuzzy controller at Beijing Jinsong East Intersection.The simulation shows that the fuzzy method outperforms the fixed-time method.The strategy can deal with more stochastic and more uncertain traffic flow.
