Abstract

Global climate change has rendered transportation systems vulnerable to extreme weather conditions. A thorough assessment of network resilience is crucial to maintain the smooth operation of the road network. This study develops a three-dimensional resilience evaluation model that accounts for the impact of capacity degradation and sheds light on the resilience of road networks. We investigate the degradation mechanism of road network performance in a rainfall environment. Specific rainstorm weather scenarios were generated using the Monte Carlo simulation method. The road traffic network in the Chengdu metropolitan area was selected for validation and analysis. When meteorological conditions exceed the secondary intensity, the road network becomes more vulnerable to increased traffic flow. Betweenness and degree centrality are indicators of regional importance. Different recovery strategy priorities must be developed for different interference scenarios.

都市圈道路交通网络弹性研究

全球气候变化使交通系统容易受到极端天气条件的影响。全面评估路网弹性对于维持路网的平稳运行至关重要。本研究建立了一个考虑容量退化影响的三维弹性评价模型，为路网弹性的研究提供了新的思路。我们研究了降雨环境下道路网络性能的退化机制。使用蒙特卡罗模拟方法生成了具体的暴雨天气情景。选取成都都市圈道路交通网络进行验证和分析。当气象条件超过二级强度时，路网更容易受到交通流量增加的影响。中间度和度中心性是区域重要性的指标。针对不同的干扰情况，必须制定不同的恢复策略优先级。
