Modelling cascade dynamics of passenger flow congestion in urban rail transit network induced by train delay

A research into congestion propagation mechanism of urban rail transit passenger flow in train delay scenario is great significance to the formulation coordinated limitation measures among operation lines networks. This paper presents a methodology for modelling cascade dynamics congestion. In this method, firstly, computing method network states based on load entropy proposed describe overall conditions network. Secondly, developed and computation formulas capacity nodes have been established combining with comprehensive consideration nodes’ topological attributes. Thirdly, Trip Betweenness Centrality calculated. Considering function line distribution strategy, calculate state transition real case study Beijing Metro Line 10 used demonstrate methodology. The results show that values distances from initial failure can be determined spreading scope disrupted metro adjacent lines.
