摘　　要：信号配时优化是提高交叉口通行能力,改善路网通行状况的重要途径。文章针对部分交叉口非对称交通流量的特征,改变以往采用对称相位的设置方法,通过改造交叉口渠化、设置非对称相位及伴随相位的方法对交叉口交通信号进行优化,解决了非对称交通流占用大量有效绿灯时间问题;使用Vissim软件进行交通仿真,仿真结果及实践表明,伴随相位对改善非对称交通流交叉口通行状况具有一定的优越性。Timing optimization is an important method of improving signal intersection capacity and optimizing traffic network running status. Aiming at unparallel flow of some intersections, a chaperonage phase is used to optimize the traffic signal. This method does not adopt the same phase which was usually used, but applies the optimal split approach function, sets unparallel phase and adjusts correlated phase, thus solving the problem that unparallel flow occupies lots of effective green light time. Traffic simulation is made by use of VISSIM software, and the result and practice show that the chaperonage phase has superiority in optimizing the intersection running status.
