The urban rail transit system is threatened by various kinds of risk events, so it is necessary to explore system robustness and guarantee safe operation. Considering the overall topological structures of urban rail transit network (URTN), the complex network theory is adopted. After calculating the topological parameters and robustness analysis parameters, the attack strategies for URTN are established. The proposed methodology is applied to the Singapore Mass Rapid Transit System. The results demonstrate that malicious attacks have more serious impacts on system robustness than random attacks. In addition, the nodes that link to different sections of the network, connect a cluster of nodes to the main network, or connect to more than one rail transit line are identified as important nodes of the network. The obtained results could supply valuable references for the safety management of URTN. The proposed methodology could also be used for other URTN robustness analyses.

Key words: robustness, urban rail transit network, complex network, system safety
