The invention provides a key road section recognition method, device and equipment, a medium and a program product, and relates to the technical field of road recognition, and the method comprises the steps: obtaining the importance of each road section in a road network according to road network information data and traffic data of a gate node; according to a pre-constructed road network cascade failure model, obtaining a vulnerability index value of each road section in the road network; wherein the road network cascade failure model is constructed by adopting a road section self-failure probability determined based on road condition data and a road section failure consequence strength determined based on map data; and according to the importance degree and the vulnerability index value of each road section, key road sections in each road section are identified, and the key road sections are used for operation monitoring of the road network. According to the method, the key road section identification precision and efficiency can be effectively improved.

    本申请提供一种关键路段识别方法、装置、设备、介质及程序产品,涉及道路识别技术领域,该方法包括:根据路网信息数据以及卡口节点的流量数据,获取路网中各路段的重要度;根据预构建的路网级联失效模型,获取路网中各路段的脆弱性指标值;其中,所述路网级联失效模型是采用基于路况数据确定的路段自身失效概率,和基于地图数据确定的路段失效后果强度构建得到;根据各路段的重要度以及脆弱性指标值,识别出各路段中的关键路段,所述关键路段用于路网的运行监控。通过上述方法,可以有效提高关键路段识别的精度和效率。
