Abstract

To analyze the robustness of the Chongqing metro network under emergencies, this paper takes the Chongqing metro network as the research object. Utilizing complex network theory, a Space-L model of the Chongqing metro network is constructed. The topological characteristics of the network are quantitatively analyzed, and the robustness of the network under different attacks is examined through simulation experiments. The results indicate that the Chongqing metro network exhibits strong robustness against random failures, while its connectivity declines rapidly under deliberate attacks. Therefore, it is recommended to enhance the inspection and maintenance of key stations in the Chongqing metro and formulate backup plans to ensure the service level of the network to the greatest extent.
