A comprehensive importance measure method of railway network components is proposed in this paper. First, the railway network construction method is developed based on the physical layout and travel time. The betweenness centrality and network efficiency are extended by combining the network topology and traffic flow to measure the link and node importance. Because single available measure cannot reflect the overall network component criticality, a comprehensive importance measure method is developed by using the weighted average value of the two metrics. Finally, the proposed method is applied to measure the link and node importance of Chinese high speed railway network. A complete picture of railway network component criticality is obtained.
