摘要
提出了一种基于模糊逻辑的交叉口信号控制算法,并通过对相位顺序进行优化,获得了更好的控制效果。与传统的信号模糊控制算法相比,该算法具有相位组合灵活、延误时间小等优点,能够有效解决交通流不平衡的问题,更适应城市交叉口实时变化的交通状况。仿真研究表明:该控制算法能够大大减少车辆延误时间,是进行城市智能交通控制的一种实用且行之有效的方法。
A signal control algorithm is presened that brined 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.
