摘要: 针对现有城市轨道交通网络关键站点识别方法对站点双向中断场景下列车运行交路调整过程考虑不足的问题,提出一种双向中断下城市轨道交通网络关键站点识别方法。假设站点失效情况为双向中断运营,根据线网中折返站点布设情况确定节点失效范围。从网络连通性、网络拓扑特性和站点自身属性3方面选取评价指标,采用TOPSIS法综合评价城市轨道交通网络站点重要度,选取成都地铁网络作为实例,识别成都地铁网络关键站点。结果表明,成都地铁网络关键站点主要分布在环线与射线相交区域的换乘站;识别结果中部分非换乘站点的重要度会由于其折返区段内包含其他重要车站得到提升,本文提出的方法能够识别出部分原节点移除法下容易忽略的站点,使评价结果更符合实际。

Abstract: Since the existing methods of identifying critical stations for urban rail transit networks seldom consider the process of train operation interchange adjustment in the situation of bidirectional disruptions, a critical station identification method of urban rail transit networks under bidirectional disruptions is proposed. Assuming that the station failure situation is a bidirectional disruption of operation, the node failure range is determined based on the distribution of turnback stations in the network. Evaluation indicators are selected from three aspects: network connectivity, network topology and station attributes, while the importance of urban rail transit network stations is comprehensively evaluated by TOPSIS. The metro network in Chengdu system is selected as an example to identify the critical stations. Results show that the critical stations of Chengdu metro network are mainly distributed in the interchange stations where the ring line and the ray line intersect. The importance of some non-interchange stations in the identification results is increased due to the inclusion of other important stations in the turnback section. The proposed method can identify some stations that are easily ignored by the original node removal method, making the evaluation results more realistic.
