摘要：
Urban rail transit lines and stations are interconnected and closely linked. The node failure spreads rapidly in the network, causing a wide range of congestion and affecting the normal operation of the entire network. Firstly, combined with the characteristics of rail transit, the cascading failure phenomenon of urban rail transit network is analyzed. The improved edge weight function is applied to analyze the change of node state, and then the reassignment of traffic is generated. Then, the cascaded failure model of urban rail transit network is established, and the network failure scale and damage degree are used to evaluate it. The cascaded failure process is simulated and the cascading failure resistance of urban rail traffic network under different failure strategies is analyzed. Finally, the Beijing rail transit network is taken as an example to carry out an empirical study. The results of this paper have important reference significance for the rational planning, structural optimization and operation safety of the rail transit network. Copyright © 2018 by Science Press.
