Importance evaluation of subway network sites and simulation test of damage resistance
摘要
Abstract
The subway station is an important part of the urban rail transit network,and accidents at the station can seriously affect the normal operation of subway network.To identify the key stations,the Passenger-flow-K-shell(PK)evaluation indicator with considering passenger flow attributes was proposed based on the k-core idea.The comprehensive importance evaluation method for stations was constructed with integrating degree,intermediate number and eigenvector centrality by multi-criteria decision analysis.The simulation test of damage resistance for network was designed to verify the importance of key nodes to the network performances.Taking Beijing rail transit as example,the experiment was conducted to rank the comprehensive importance of the Beijing subway station led by Ping'anli Station.The research results show that the damage resistance performance of Beijing rail transit is greatly affected by key nodes.After the key nodes are removed,the network performance is seriously lost.Subway departments should focus on the protection of stations with high comprehensive importance and improve the network survivability.关键词
