为提高信号交叉口通行能力，利用二元饱和度方法，对交叉口单相位的车辆做延误分析，推导了适用于任意交通情况的路口延误模型，并对该模型进行算例分析。通过基于传统饱和度与二元饱和度控制约束条件下仿真对比验证，本延误模型计算简单易实现、在较高饱和度下路口车辆排队长度比传统饱和度控制方式短，另外时延也得到一定改善。

In order to improve the traffic capacity of signalized intersections,the delay of single phase vehicles in signa-lized intersections was analysed with the method of duality saturation degree,and then the signalized intersection delay model was established. The analysis of examples for the model was conducted. The results of simulation contrast between both the tradi-tional saturationdegree control method and the duality saturation degree control method show the latter can efficiently decrease in-tersection delay and reduce the queue length of vehicles under high saturation The verification result indicates that the delay model is simple and easy to achieve.
