Key Risks of Rail Transit Operation Based on Complex Network
Publication: ICCREM 2021
ABSTRACT
In the operation of rail transit, there are many uncertain risks which may cause accidents. To guarantee the safe operation of rail transit, the complex network was adopted to establish a data set containing 422 risk chains. The risk was regarded as a network node, and the evolution relationship between risks was taken as a network chain to build the risk relationship network. To study the urban rail transit operation risk and its evolutionary relationship, the overall characteristics, key nodes, and key risks’ chains of the risk network are analyzed by network density, network centrality, and degree. The results show that panic, disturbance, retention, congestion, fire, violent terrorist attacks, passively fall rail, and fall down are the key risks in the risk network of rail transit operation. The research results can provide operational references for the rail transit operation managers in risk preventing and controlling.
