利用冲突点的车流特点确定信号控制周期

Using Traffic Stream Characteristics of Conflict Point to Determin Signal Time of Signalized Intersection

信号周期是交叉口交通信号配时的一个重要参数 .通过回顾传统的配时方法 ,指出了不足 .通过对交叉口冲突点交通运行状况分析 ,利用可接受间隙理论 ,提出了信号周期的计算方法 ,更符合实时变化的特点 。

Signal time is an important parameter of intersection signal timing. After reviewing traditional signal timing methods , their shortcomings are analyzed. Based on the gap acceptance theory, the formula of calculating signal time is deduced by using running modes of the stream at the conflict point . Compared with other signal time models, it is more efficient in real time control.
