The invention provides an urban road traffic network disaster-resistant toughness evaluation method. The method comprises the following steps: 1, collecting road traffic network information; 2, selecting nodes and links; 3, drawing a road traffic network visual model and numbering each node and each link; 4, acquiring the emergency resource occupation condition of each numbered node, and acquiringthe length data, travel time data and average hour traffic volume data of each numbered link; 5, calculating the node importance Ii of the node i; 6, calculating the weight degree of each independentpath between the nodes i and j; and step 7, calculating a network disaster-resistant toughness capability evaluation index RPM. Due to the adoption of the technical scheme, the invention provides theevaluation method special for the disaster-resistant toughness capability of the urban road traffic network, and the blank in the aspect of evaluating the disaster-resistant toughness capability of the urban road traffic network is filled.
本发明提供一种城市道路交通网络抗灾韧性能力评估方法,包括以下步骤:步骤1、搜集道路交通网络信息;步骤2、选择节点和链路;步骤3、绘制道路交通网络可视化模型并对各节点和链路进行编号;步骤4、获取各编号的节点的应急资源占有情况,获取各编号链路的长度数据、行程时间数据和平均小时交通量数据;步骤5、计算节点i的节点重要度Ii;步骤6、计算出节点i,j间各条独立路径的重量度步骤7、计算出网络抗灾韧性能力评价指标RPM。由于采用了上述技术方案,本发明提供了一种专门针对城市道路交通网络的抗灾韧性能力的评估方法,填补了针对城市道路交通网络的抗灾韧性能力评估方面的空白。
