Vulnerability Analysis of High-speed Rail Network in the Face of Emergency
Abstract
Taking the high-speed railway network in the three northeastern provinces of China as an example, this paper simulates the changes in the networks characteristic values under scenarios of continuous node failures and single node failures, thereby assessing the networks vulnerability. The research results show that the high-speed railway network in the three northeastern provinces has a distinct hierarchical structure. Specifically, Nodes are sorted by their degree values from highest to lowest, and then nodes are continuously removed in sequence. The changes
in the networks characteristic values are calculated. The results indicate that as nodes fail continuously, the high-speed railway network in the
three northeastern provinces exhibits significant fluctuations. This suggests that when nodes are continuously attacked, the high-speed railway
network shows a high level of vulnerability.
