摘　　要：提出了一种基于模糊逻辑的交叉口信号控制方法 ,此方法不需要建立复杂的交通流模型 ,可以有效地解决交通信号控制过程中复杂和随机性难题。同时应用加权系数的遗传算法对模糊逻辑控制器的参数进行了优化。仿真结果表明模糊逻辑控制可以成功地应用于城市交叉口交通信号控制中。A traffic signal control method using fuzzy logic controller in urban road intersection is proposed.It is not needed to build the traffic flow model for signal control approach in the intersection using the method based on the fuzzy.However,this method can effectively solve the stochastic and unknown problems in this dynamic system. A GA of weighted coefficient is adopted to optimize the parameters of fuzzy logic controller.The experimental simulation results show that fuzzy logic controller can be successfully applied in traffic signal control for urban road intersection.
