The invention provides a multi-traffic subarea distributed collaborative optimization method and system based on a double-layer architecture, and relates to the technical field of traffic control and automatic control, and the method comprises the steps: building a weighted directed graph through a road network model, and dividing the weighted directed graph into a plurality of traffic subareas; based on the macroscopic basic diagram of each traffic sub-region, constructing an upper-layer multi-sub-region collaborative optimization model, and obtaining an optimal accumulated vehicle number of each traffic sub-region under collaborative control; optimizing the timing of each intersection in the traffic subareas by taking the optimal accumulated vehicle number of each traffic subarea as the constraint of the lower-layer single subarea optimization control model to obtain an optimal timing scheme of the controlled road network; according to the method, the overall traffic efficiency of each sub-region and a road network and flow distribution balance among the sub-regions are considered, based on a double-layer cascade architecture, the upper layer obtains the optimal accumulated vehicle number of each sub-region under cooperative control, through sub-region boundary control, cascading with the lower layer is carried out on the conditions of intersections in the sub-regions, parameters are continuously updated, and multi-sub-region cooperative optimization is carried out.

    本公开提供了基于双层架构的多交通子区分布式协同优化方法及系统,涉及交通控制及自动控制技术领域,包括:利用路网模型构建有权有向图,将有权有向图划分为若干个交通子区;基于各个交通子区的宏观基本图,构建上层的多子区协同优化模型,得到协同控制下各个交通子区的最优累计车辆数;将各个交通子区的最优累计车辆数,作为下层单子区优化控制模型的约束,对交通子区内部每个交叉口配时进行优化,得到受控路网的最优配时方案;本发明考虑各子区自身和路网整体通行效率、子区间流量分配均衡,基于双层级联架构,上层求得各子区在协同控制下的最优累计车辆数,通过子区边界控制,与下层对子区内部各交叉口情况进行级联并不断更新参数,进行多子区协同优化。
