摘　　要：信号配时优化是提高平面交叉口服务水平的重要途径。在对车辆微观运动特性进行分析的基础上,对传统信号配时算法作出了改进,得到新的信号配时算法,并应用于武昌团结路交叉口信号配时,计算结果表明,改进的信号配时方案能够满足最小行人过街时间的要求,可以有效避开各相位显示绿灯时间调整的问题。The optimization of signal timing is an important way to improve intersection level of service. In this paper, we improve the traditional signal timing algorithm on the basis of micro-movement characteristics of vehicles. And therefore, we have a new signal timing algorithm, and applied it to the signal timing in the intersection of Tuanjie Road. The timing results showed that improved signal timing program can satisfy the demand of minimum time for pedestrian crossing the street, and it can also effectively avoid the problem of the adjustment in showing green time for each phase.
