The invention discloses a road network vulnerability assessment method and device, electronic equipment and a storage medium. The method comprises the following steps: generating a target travel matrix of driving vehicles in a target detection area according to vehicle driving data of the driving vehicles in the target detection area; determining a road weighted directed graph of the target detection area according to the road topological graph of the target detection area and the target travel matrix; and determining the corresponding network efficiency when each node is deleted one by one in the road weighted directed graph, and determining the road network vulnerability according to the network efficiency. By adopting the technical scheme of the invention, the traffic flow is introduced when the road weighted directed graph is constructed and the road topology condition in the target detection area is considered, so that a result more suitable for the actual condition can be obtained when the vulnerability of the road network is determined, and the calculation process is ensured to be clear while the accuracy of the result is improved.
本发明公开了一种路网脆弱性评估方法、装置、电子设备及存储介质。该方法包括:根据目标检测区域内行驶车辆的车辆行驶数据,生成目标检测区域内的行驶车辆的目标出行矩阵;根据目标检测区域的道路拓扑图与目标出行矩阵,确定目标检测区域的道路加权有向图;确定道路加权有向图中逐一删除各个节点时对应的网络效率,并依据网络效率确定路网脆弱性。采用本申请技术方案,使得构建道路加权有向图,在考虑目标检测区域内道路拓扑情况时,引入了车流量,使得在确定路网脆弱性时,能够得到更为切合实际情况的结果,从而提高了结果的准确性的同时,保证了计算过程的清晰。
