The invention discloses an intelligent traffic control method and system for an urban road intersection. The invention discloses an intelligent traffic control method for an urban road intersection, which analyzes real-time flow of each entrance lane at the intersection, and comprises a direction-variable lane intelligent adjustment control algorithm: analyzing space-time resource utilization conditions of lanes with the same phase and different flow directions according to the number and the type of vehicles passing through each lane, switching conditions of the direction-variable lane are obtained, and dynamic adjustment of the direction-variable lane is achieved; and a signal timing intelligent adjustment control algorithm: based on the traffic flow detection data, using a saturated time headway analysis method to analyze the green light utilization condition at the end of the green light, and judging the saturated time headway to realize the dynamic change of the signal duration of the intersection so as to obtain a signal timing dynamic adjustment scheme containing the variable lane at the same phase of the intersection. According to the invention, dynamic balance between space-time resources and traffic demands of the road intersection is realized, and the method is of great significance to improvement of urban traffic operation conditions.

    本发明公开了一种城市道路交叉口智慧交通控制方法及系统。一种城市道路交叉口智慧交通控制方法,通过对交叉口各进口车道实时流量进行分析,包括:可变向车道智慧调整控制算法:根据通过各车道的车辆数和车辆类型,分析同一相位不同流向车道的时空资源利用状况,得到可变向车道的转换条件,实现对可变向车道动态调整;以及,信号配时智慧调整控制算法:基于交通流检测数据,采用饱和车头时距分析法对绿灯末尾绿灯利用情况进行分析,对饱和车头时距的判断实现对交叉口信号时长的动态改变,得到交叉口同一相位含可变车道的信号配时动态调整方案。本发明实现了道路交叉口时空资源与交通需求的动态平衡,对改善城市交通运行状况具有重要意义。
