Using Network Theory to Explore the Vulnerability of the Subway System

The subway has become the most effective form of transport for relieving traffic congestion in China. The vulnerability of the subway should be studied to improve the safety level in subway operation. In this paper, first of all, the general analytical method of systemic vulnerability was expatiated thoroughly. Then, the centrality theory was introduced to analyze the subway equipment system network (SESN). Next, an undirected SESN was established based on in-depth analysis of the subway system. In the end, based on SESN, vulnerability of the subway was identified by aid of PAJEK and R software platform. The study indicated that the critical vulnerability of the subway system is optical fiber system and automatic train supervision system, and there is a strong positive correlation between the vulnerability and the centrality.
