序言交通信号是用来给占据同一空间相互冲突的车流分配通行时间的。时间分配的方法对交叉路口及其车道的通行能力都有巨大影响。为此，通过对有关路口交通信号灯控制参数以及通行能力的分析，使我们对设置的交通信号控制参数是否合理，有一个量的检验。通过对交叉路口通行能力 Preface Traffic signals are used to allocate traffic time to traffic streams that occupy the same space. The method of time allocation has a huge impact on the capacity of intersections and their lanes. To this end, through the intersection traffic lights on the control parameters and capacity analysis, so that we set the traffic signal control parameters is reasonable, there is a quantitative test. Passing to the intersection capacity
