摘要: 城市内涝灾害突发性强、覆盖范围广,严重影响道路交通安全。灾后及时评估交通路网性能并制定修复策略,对于交通网络快速恢复具有重要意义。本文综合考虑城市内涝积水下的路径通行时间和使用频率,基于路径介数中心性和人口加权改进网络效率评估模型。在此基础上,构建路网性能恢复目标函数,分析不同偏好策略下的阻断点修复次序。以郑州“7·20”特大暴雨洪涝灾害下四环路网为例,实验结果表明:城市内涝导致部分路段和交叉口出现交通中断或减速,改进网络效率模型可以量化积水环境对于路网交通性能的整体影响;内涝积水对道路网络效率影响最大的是全阻断高介数类型的路段,半阻断高介数的路段在一定程度上比全阻断低介数的路段影响更大;根据网络效率恢复曲线可以看出,效率优先策略优于类型优先和位置优先策略;交叉口修复不一定优于路段修复,但全阻断破坏相较于半阻断在一定程度上具有更高的修复优先级。

Abstract: Urban waterlogging disasters are sudden highly and extensive spatially, which severely threaten the road traffic safety. The rapid post-disaster assessment of road network performance and formulation of effective repair strategies is essential for restoring the traffic functionality. Considering both the travel time and usage frequency under inundated conditions, this study develops an improved evaluation model of network efficiency by incorporating the betweenness centrality of path and weighted population. On this basis, a road network objective function for performance recovery is constructed to analyze the optimal repair sequence of the disrupted nodes and links under different preference strategies. Using the Zhengzhou Fourth Ring Road network during the catastrophic“7·20”rainstorm and flooding event as a case study, the experimental results indicate that urban waterlogging causes the traffic interruptions or speed reductions on certain road segments and intersections, and the improved model of network efficiency effectively quantifies the overall impact of the inundation on road network performance. The fully blocked segments with high-betweenness impose the greatest reduction in network efficiency; moreover, the partially blocked segments with high-betweenness can, to some extent, exert a greater impact than which in fully blocked segments with low betweenness. The recovery curves of network efficiency further show that the efficiency-first strategy outperforms the type-first and location-first strategies. The repair at intersection is not necessarily superior to that along the road segments, but the fully blocked disruptions generally warrant a higher repair priority compared with the partially blocked ones.
