信号交叉口配时方案的最优策略是平衡关键车道组的v/c比和所有车辆延误最小化.本文在研究已有控制延误模型的基础上,提出一种新的随机控制延误计算模型.根据不同地区各城市信号交叉口的交通流运行特性,在信号优化策略基础上兼顾考虑其通行能力,给出实时实地的信号配时方案策略.实例说明该定时信号交叉口配时方案.

英文摘要：

The v/c ratio of critical lane group and minimum delay of vehicle are the timing optimization scheme for signalized intersection. This paper present a new random control delay computation model based on known. According to different urban the operation features of signalized intersections,the optimization scheme is proposed for signalized timing based on the calculation of timing optimization and capacity at signalized intersections. At last,the example results show that it is suitable to use timing at signalized intersections.
