A Method for Evaluating the Importance of Regional Rail Transit Nodes under the Sense of Cascaded Failure

Published: 14 October 2021 Publication History

Abstract

Regional rail transit is a comprehensive rail transit system composed of multiple types of rail transit systems developed to meet the needs of urban agglomeration economic integration. Due to its integrality, interaction and coupling, single-point risks will "pull one hair and the whole body is affected" through spreading and cascading, forming an overall deep impact on the overall safety of the road network. Aiming at the existing rail transit node importance evaluation methods that seldom consider the problem of cascaded failure, this paper proposes a node importance evaluation method in the sense of dynamic cascaded failure to provide theoretical support for the protection and optimization of key nodes in the road network. Finally, a simulation example of the regional rail transit network in Chengdu-Chongqing area verifies the effectiveness of this method.
