Urban Rail Transit System Network Reliability Analysis Based on Coupled Map Lattice Model

Urban rail transit complex network consists of topological network and passenger flow network. This paper proposes the passenger flow weighted network reliability evaluation indexes, so as to assess the impacts of passenger flows on network reliability. The actual passenger flow weight of urban transit network nodes was obtained from Shanghai metro public transportation card data, which was used to measure the reliability of passenger flow weighted network. The dynamic model of Shanghai urban rail transit network was constructed based on the coupled map lattices (CML) model. The processes of cascading failures caused by network nodes under different situations were simulated, thus to measure the changes of passenger flow weighted network reliability during the processes. The results indicate that when the scale of network damage reaches 50%, the reliability of passenger flow weighted network approaches zero. Consequently, taking countermeasures during the initial stage of network cascading will effectively prevent the disturbances from spreading in the network.
