The invention discloses an urban congestion road network key path identification method, electronic equipment and a medium, and the method comprises the following steps: firstly, obtaining an accident point, determining a downstream intersection closest to the accident point based on the accident point, and taking the downstream intersection as a starting point; determining the edge of a congested area, and taking each intersection on the edge of the congested area as an end point; determining a plurality of shortest path sets under the combination of the starting point and the plurality of terminal points based on a road network map; secondly, the traffic volume, the steering ratio and the road section lane number of the downstream intersection and all the intersections are obtained, and the comprehensive correlation degree of the road section is calculated based on the traffic volume, the steering ratio and the road section lane number; calculating the comprehensive association degree of the shortest path based on the comprehensive association degree of the road section; and finally, based on the comprehensive association degree of the shortest paths and a preset association degree threshold value, determining key paths needing to be interfered in the plurality of shortest path sets.
本发明公开一种城市拥堵路网关键路径识别方法、电子设备及介质,包括如下步骤:首先,获取事故点,基于所述事故点,确定所述事故点最近的下游交叉口,并将所述下游交叉口作为起点;确定拥堵区域边缘,将所述拥堵区域边缘上每个交叉口作为终点;基于路网图,确定所述起点与多个所述终点组合下的多条最短路径集合;其次,获取所述下游交叉口与所有的所述交叉口的交通量、转向比和路段车道数,基于所述交通量、转向比和路段车道数,计算出路段的综合关联度;基于所述路段的综合关联度计算出最短路径的综合关联度;最后,基于所述最短路径的综合关联度以及预设的关联度阈值,确定所述多条最短路径集合中需要干涉的关键路径。
