摘　　要：模糊控制不需建立被控对象的精确数学模型,特别适用于具有较大随机性的城市交通控制。对一类特殊路口的交通流进行了分析,确定了相应的信号配时方案。提出了以当前相的主队列和后继相的主队列共同决定信号配时的模糊控制方法,阐述了模糊控制器的整个设计过程。以通过交叉口的平均车辆延误为性能评价指标进行了仿真实验,仿真结果表明模糊控制优于定时控制。It is unnecessary for fuzzy control to built exact mathematic model of control system, so fuzzy control is applicable especially to control urban traffic with great random characteristics. Traffic flow of a special intersection was analyzed and the scheme of signal timing was put forward. Based on the main queues of current phase and next phase, fuzzy control was applied and the design procedure of fuzzy controller was expounded. With the performance of average vehicle delays through the intersection, a simulation experiment was performed. The simulation results show that the control effect of fuzzy control is better that that of timed control.
