融合动态指标的山西、山东、河南和河北高速公路网络韧性评估
Resilience Assessment of Shanxi, Shandong, Henan, and Hebei Expressway Networks Incorporating Dynamic Indicators
重大突发事件的干预突显了高速公路网络韧性评估的重要性。基于复杂网络和韧性三角理论,构建融合局部、全局与社会属性的节点综合性能动态指标评估体系,并进一步提出高速公路网络韧性系统性评估方法。该韧性评估流程分为初始、破坏、恢复和稳定4个阶段,使用6种破坏和恢复策略(节点度、特征向量、介数、可达性、社会属性和随机选择),通过网络独立路径数、网络效率和网络连通度3个关键指标实现高速公路网络分析。以山西、山东、河南和河北为例,结果表明:在初始阶段,山西、山东、河南和河北高速公路网络拥有较优网络独立路径数,其抗风险能力较强;在破坏阶段,网络效率、网络独立路径数和网络连通度分别下降了94.32%、98.18%和99.63%,验证了公路网络的破坏吸收能力;在恢复阶段,可达性恢复策略韧性三角形面积最小、韧性最强,而随机恢复策略变化速率最慢;在稳定阶段,山西、山东、河南和河北高速公路网络效率韧性优于网络连通度和网络独立路径。建议优先保护新乡市、濮阳市等节点度取值较大的城市节点,以提升区域高速公路网络韧性。
The evaluation of expressway network resilience has been emphasized due to significant global emergencies. Utilizing complex network theory and the resilience triangle model, a dynamic system was developed to assess the comprehensive performance of nodes, incorporating local, global, and social attributes. A method for evaluating the resilience of expressway networks was proposed, consisting of four stages: initial, disruption, recovery, and stabilization. Six disruption and recovery strategies (node degree, eigenvector, betweenness, accessibility, social attributes, and random selection) were applied to analyze the network's performance using three key indicators: the number of independent paths, network efficiency, and network connectivity. A topological map of the expressway network spanning the provinces of Shanxi, Shandong, Henan, and Hebei were constructed, and the resilience changes under various disruption and recovery strategies were analyzed. The findings indicate that in the initial stage, the expressway network exhibits a relatively high number of independent paths, suggesting robust anti-risk capabilities. During the disruption stage, network efficiency, the number of independent paths, and network connectivity decrease by 94.32%, 98.18%, and 99.63%, respectively, demonstrating the network's ability to absorb disruptions. In the recovery stage, the accessibility restoration strategy, which results in the smallest resilience triangle area, exhibits the strongest resilience, whereas the random restoration strategy shows the slowest recovery rate, indicating that it should be avoided whenever possible. In the stabilization stage, network efficiency resilience is found to be superior to that of network connectivity and independent path resilience in the expressway network of the four provinces. It is recommended that urban nodes with higher degree values, such as Xinxiang and Puyang, be prioritized for protection to enhance the overall resilience of the expressway network.
