摘要
地铁站点是城市轨道交通网络的重要组成部分,站点发生事故会严重影响地铁网络的正常运营.为寻找关键站点,基于k核思想,提出考虑站点客流属性的PK(Passenger-flow-K-shell)评价指标,使用多准则决策分析法,结合度、介数和特征向量中心性构建站点综合重要度评估方法;设计网络抗毁性能仿真试验,验证关键节点对网络性能的影响;最后以北京轨道交通为例,试验得到以平安里站为首的北京地铁站点综合重要度排序.研究结果表明:北京轨道交通抗毁性能受关键节点影响较大,关键节点遭到移除后,网络性能损失严重.地铁部门应对综合重要度高的站点进行重点防护,提高网络的抗毁性能.
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.
