【Abstract】 A signal control algorithm is presened that based on fuzzy logic and the control result is getting through optimizing the phases’ order of traffic signal.Compared with traditional signal fuzzy control algorithm,the algorithm in this paper possesses flexible phase combination with little delay,it can solute the imbalance of traffic flow and adapt to the real-time change of traffic status very well at the intersection.The simulation result indicates that the control algorithm can greatly reduce vehicle delay,it is a practicable and useful method for urban intelligent traffic control.更多还原
