The invention discloses a real-time dynamic variable lane and trunk green wave collaborative optimization method, and relates to a traffic green wave control technology. The problems that in the prior art, response is delayed and a strategy fails in an emergency scene when variable lane and green collaborative optimization is carried out based on historical data of a target intersection are solved. According to the method, the flow of the target intersection is predicted based on the flow data of the first two periods of the upstream intersection, the direction of the variable lane is determined according to the saturation of the lane direction corresponding to the target intersection, and the signal phase timing in the signal period is optimized by taking the minimum total delay of the entrance lane group of the key intersection as the target; therefore, cooperative control of variable lanes and traffic green waves is realized. The influence of the upstream intersection on the target intersection is integrally associated, the control strategy of the target intersection can be rapidly adjusted according to the dynamic change of the upstream intersection, the method is more flexible, data mutation caused by emergencies can be dealt with, and the use value of the control strategy is improved.

    本发明公开了一种实时动态可变车道与干线绿波协同优化方法,涉及交通绿波控制技术;解决了现有技术中基于目标交叉口历史数据进行可变车道和绿协同优化在紧急突发的场景中反应迟滞,策略失效的问题。本发明基于对上游交叉口的前两个周期的流量数据对目标交叉口的流量进行预测,并依据目标交叉口对应车道方向的饱和度确定可变车道方向,以关键交叉口进口车道组总延误最小为目标,优化信号周期内的信号相位配时,从而实现可变车道和交通绿波的协同控制;从整体上关联到上游交叉口对目标交叉口的影响且可以根据上游交叉口的动态变化快速调整目标交叉口的控制策略,更具有灵活性,能够应对紧急突发情况带来的数据突变,提升了该控制策略的使用价值。
