摘　　要：从交通信号控制的角度,对城市干道的交通信号控制策略及其控制优化参数(周期时长、绿信比、相位差)进行分析,并结合虎门镇连升路的交通状况,采用模糊控制方法实现城市交通干道的优化协调控制。通过VISSIM软件仿真,分析对连升路分别采用模糊协调控制方案、传统数解法协调控制方案及单点控制方案的效果并进行比较,结果表明模糊协调控制方案明显优于其他两种方法。Traffic signal control strategy of urban trunk road and its optimal control parameters （ cycle length, split and offset） are analyzed from the angle of traffic signal control. Taking the traffic situation of Liansheng road of Humen into account,the optimum coordinate control of urban trunk road is realized through fuzzy logic algorithm. VISSIM simulation software is used to＇analyze and make a comparison among effect of the schemes of fuzzy logic coordinate control, tradition algebraic analysis method coordinate control and single point control. The result shows that the scheme of fuzzy logic coordinate control is much better than other two schemes.
