摘要
网络结构是城市轨道交通网络的一个重要特征。异常事件下网络结构特征的变化往往决定了事件所产生的影响。以新加坡的轨道交通网络为对象,首先基于3类中心度指标分析网络的结构特征,对站点和线路进行了比较;然后分析了1个站点关闭这类异常事件下网络结构特征指标发生的变化,基于此能界定破坏网络连通性及明显改变网络结构均衡性的2类关键站点;最后阐述了分析结果在城市轨道交通系统运营管理方面的应用价值。
Network structure is a key characteristic of urban rail transit network. The structural changes of rail transit network in incident circumstances will determine the conse- quences caused by the incidence itself. In this paper, Singa- pore metro network is taken as the object, and based on the structural characteristics of three kinds of centrality index, important stations and lines are identified and compared. Then, the changes of network structural indices are ana- lyzed when astation is closed, thus the disconnection of the network and the unbalance of the network structure of two kinds of critical stations could be identified. Finally, the ap- plication value of the analytic results in urban rail transit operation and management is described.
