Abstract: This paper employs system science and complex network theory to abstract the topological structure and to analyze the connectivity of urban rail transit networks. Meanwhile, movingblock technology is applied to calculate the transportation functionality and to investigate the static and dynamic vulnerability based on transportation functionality of urban rail transit networks. Considering Nanjing metro network as example, the results show that the connectivity of Nanjing metro network is very poor. For static failures, Nanjing metro network is very vulnerable when suffering malicious attacks, and the highest load node-based attacks can result in more damages than the largest degree node-based attacks. For dynamic failures, the results show that the transportation functionality becomes larger and larger with the increase of the control parameter of load capacity, which illustrates that the reliability becomes higher and higher with the increase of the construction cost. Therefore, we can declare that there exists a tradeoff between the reliability and construction cost of urban rail transit networks.
