Evaluation Method for Node Importance of Urban Rail Network Considering Traffic Characteristics

As a sustainable means of public transport, the safety urban rail transit is significant section and highly important in development. Research on importance stations plays an role improving reliability networks. This paper proposed improved method for evaluating topology network, which was used to identify key that affect network performance. based complex theory, considering traffic characteristics runs specific lines integrating structural interrelationship where are located. Hereafter, this will be abbreviated as CLI. In order verify high evaluated by were had great impact performance, designed comparative attack experiment betweenness centrality The carried out taking Suzhou Rail Transit (SZRT) example largest connected subgraph well efficiency indicators measure results showed CLI greater performance could better evaluate than node degree centrality.
