摘　　要：该文针对城市交通道路十字交叉路口的交通灯信号控制存在的问题进行了探讨,提出一种新的控制方案,由PLC承担主要的控制任务,采用模糊控制的算法,通过主相位和辅相位的自选择,建立拟人化的多相位信号灯智能控制。实验表明,该控制方法对减少车辆平均延误时间、提高路口通行能力具有很好的控制效果。The content of text is concentrated on the discussion in view of the municipal transportation crossroad traffic light signal control existence question, proposed one kind of new control plan, uses the fuzzy control the algorithm, through the host phase and the auxiliary phase from the choice, establishes the personification the signal light intelligenee control, and undertakes the main control task by performance superior PLC. Indicated after the modeling that, this control method to reduces average delay time of the vehicle to have the obvious control effect .
