The invention provides a control method and system based on congestion backtracking. The method comprises the following steps: acquiring vehicle information of a congestion point; using the vehicle information to construct an influence intensity model of a congestion point so as to determine a congestion influence intensity value of any path; and guiding the vehicles at the congestion point by using the congestion influence intensity value, and determining a dredging road section. According to the invention, vehicle track backtracking is carried out on the congestion point, the vehicle collection space-time distribution condition is analyzed, and the intersections and the road sections influencing the congestion point are analyzed in combination with the space association relationship among the upstream intersections, the road sections and the congestion point; and according to the influence degree, fine release of induction information and targeted accurate regulation and control of a traffic signal control strategy are carried out, so that the collection speed of downstream vehicles is slowed down.

    本发明提供了一种基于拥堵回溯的控制方法及系统,方法包括:获取拥堵点的车辆信息;利用车辆信息构建拥堵点的影响强度模型,以确定任一路径的拥堵影响强度值;利用拥堵影响强度值对拥堵点的车辆进行引导,确定疏导路段。本发明通过对拥堵点车辆轨迹回溯,分析车辆汇集时空分布情况,同时结合上游路口、路段与拥堵点的空间关联关系,分析对拥堵点产生影响的交叉口和路段,并根据其影响程度进行诱导信息的精细化发布和交通信号控制策略的有针对性的精准调控,从而减缓下游车辆汇集速度。
