Resilience Evaluation Approach of Transportation Networks

To analyze the resilience of transportation networks, it is proposed to use a quantificational resilience evaluation approach. First, we represent transportation networks by an undirected graph with the nodes as cities and edges as traffic roads. Because the survival ability of transportation of a pair of cities depends on the number of independent paths between them, the resilience of a city node can be evaluated by the weighted average number of reliable independent paths with all other city nodes in the networks. The network resilience can then be calculated by the weighted sum of all node resilience. Based on the recommended approaches, the resilience of a transportation network is evaluated and analyzed. Several interesting conclusions are drawn from the computational results.
