A scientific and rational method to identify the key nodes is useful for formulating targeted management measures and the stable operation of urban rail transits. The nodes play the role of external transmission and connection locally and affect the transmission efficiency of the network globally. Since one node will inevitably be affected by other nodes in the network, an improved node degree model considering the influence of neighbor nodes was proposed to evaluate the local importance of nodes, and an improved node efficiency model considering the influence of other nodes in the network was proposed to evaluate the global importance of nodes. Based on the improved node degree model and the improved node efficiency model, a node structural importance evaluation model was constructed. This model can comprehensively reflect the local and global importance of nodes, as well as the impact of other …
