The invention discloses an intersection signal lamp phase time servo control method, which comprises the following steps of: installing counting, timing and monitoring equipment at each entrance lane,turning on when a green lamp of one entrance lane is turned on until the green lamp time of the entrance lane is over, and obtaining a time difference value between vehicle existence time and a totalgreen lamp, and an average vehicle head time interval; when the difference value is smaller than an average headway, the utilization rate of the green light time of the entrance lane is 100%, and theaverage headway is added to the green light time of the phase in the next signal period; and when the difference value is greater than or equal to one average headway, the green light time of the phase in the next signal period is reduced by one average headway. When the current phase signal time is increased, the next phase delay is started, and the total signal period is increased, but does notexceed the maximum signal period time; when the signal time of the current phase is reduced, the next phase is started in advance, the total signal period is reduced, but the green light time of thephase is longer than the shortest green light time of pedestrian crossing, and smooth dynamic adjustment of intersection signal lamps is realized.

    本发明公开了一种交叉口信号灯相位时间伺服控制方法,在每个进口道安装计数、计时和监测设备,在本进口道绿灯启动时开启,直到本进口道绿灯时间结束,得出有车时间与总绿灯时间差值,以及平均车头时距。当差值小于一个平均车头时距时,本进口道绿灯时间利用率为100%,下个信号周期本相位绿灯时间增加一个平均车头时距;当差值大于或等于一个平均车头时距时,下个信号周期本相位绿灯时间减少一个平均车头时距。当本相位信号时间增加时,下个相位延迟启动,总信号周期增加,但是不超过最大信号周期时间;当本相位信号时间减少时,下个相位提早启动,总信号周期减少,但相位绿灯时间要大于行人过街最短绿灯时间,实现交叉口信号灯的平滑动态调整。
