摘要：AbstractNowadays the rail transit is playing an increasingly important role in urban passenger trip, Meanwhile, its efficiency and reliability has been very concerned. With the tool of complex network theories, the network characteristic parameters of subway system are provided in this paper. And then the complex network models are established based on the method of spaceLand spaceP. In the case study of Wuhan city, the empirical result shows that the subway network is a scale-free network. Stability under the failure of the subway network is also analyzed. Then we define a new parameter to evaluate the important degree of one node in the subway network, which has great meaning in finding the most vital nodes (stations) and ensuring the stability of subway network. Overall, this study offers significant insights for planners in designing a more efficient and reliable system.
