Research on Structural Vulnerability of Shenzhen Metro Network Based on Complex Network Theory

To ensure the safety of the operation and improve the operational efficiency of an urban rail transit network, it is vital to study its reliability., and the complex network theory can be a practical access. In this paper, the Pajek method is used to model the three periods of Shenzhen Metro network. MATLAB is used to analysis the evaluation indices of complex network theory to assess the development of urban rail transit in Shenzhen. At the same time, how and to what extent the whole rail transit network will be affected in case of failures at transfer stations, as well as the network's reliability in this situation is studied emphatically. The simulation results show that the connectivity of Shenzhen Metro network needs to be improved. When facing deliberate attacks, key nodes of the network like Chegongmiao Station, Futian Station and Qianhaiwan Station have a greater implication on the efficiency of the entire network.
