Vulnerability Analysis of Urban Rail Transit Networks: A Case Study of Shanghai, China

摘要: Rail transit is developing rapidly in major cities of China and has become a key component urban transport. Nevertheless, the security reliability operation are significant issues that cannot be neglected. In this paper, network station vulnerabilities rail system were analyzed based on complex graph theories. A vulnerability evaluation model was proposed by accounting metro interchange passenger flow further validated case study Shanghai Metro with full-scale real-world traffic data. It identified rather robust to random attacks, but vulnerable largest degree node-based attacks highest betweenness attacks. stations large node more important maintaining size, while high critical efficiency origin-destination (OD) connectivity. The most crucial serviceability do not necessarily have throughput or structural comprehensive as therefore essential assess vulnerability, so attention can placed appropriate nodes within system. findings research both theoretical practical significance for design performance evaluation.
