摘　　要：为提高城市道路交叉路口信号控制的效率,采用面向对象的设计思想,提出了一种新的通用多相位信号控制策略.根据实际交通状况交互建立单交叉路口的通用模型,根据当前路口各车流向的车流量实时分布信息,及时调整相位数和各相位的车流向组合.实时传递路口交通情况,采用模糊控制策略,以车辆延误时间最小为优化目标,对单交叉路口的信号相位和相位绿灯时间分别进行优化.根据实测数据对该方法进行了仿真研究,并与普通信号控制方案作了对比.结果表明,这种通用信号控制方案能使交通流量总体趋于均衡,缩短了车辆延误时间.A novel general multi-phase signal control method was presented based on the idea of objectoriented design to increase the efficiency of intersection signal control. A general single intersection model was built up to adjust the phase number and traffic flow in time based on the distributing information of traffic flow for current intersection., Aimed at minimum vehicle time delay, the intersection signal phase and the green light time were optimized respectively with fuzzy control technologies. Comparison of result of simulation with application data with that of an actual signal control method show that this new signal control scheme can make the traffic flow balanced and reduce the average vehicle time delay.
