摘要:

为明确城市轨道交通网络不同站点的重要程度,提出基于网络冗余性识别关键站点的方法,从网络拓扑结构和交通功能特性2个角度定义拓扑冗余性和功能冗余性,并以上海市地铁网络为例,识别关键站点。研究结果表明:基于拓扑冗余性识别出的单个重要站点失效后,将导致网络中13.15%的交通出行(起点-终点,OD)无法连通;基于功能冗余性识别出的单个关键站点失效后,将导致网络中10.1%的乘客无法通过轨道交通网络完成出行。对于环形辐射状的轨道交通网络,基于网络冗余性识别出的关键站点主要分布在环形线路和临近环形线路向外辐射的支路上。此外,多个站点同时失效后,对网络造成的影响不仅取决于每个站点的重要程度,还取决于每个站点在轨道交通网络中的空间位置分布。

Abstract:

In order to clarify the importance of different stations in urban rail transit network, a method of identifying key stations based on network redundancy was proposed. Topological redundancy and functional redundancy were defined from the perspectives of network topology and traffic functional characteristics. And taking Shanghai metro network as an example, key stations were identified. The research results show that the failure of a single important station identified based on network topological redundancy will cause 13.15% of the traffic tralvel(origin-destination, OD) in the network to be disconnected. After the failure of a single key station identified based on network functional redundancy, up to 10.1% of passengers in the network can not complete their travel through the rail transit network. For the ring-shaped radial rail transit network, the key stations identified based on network redundancy are mainly distributed in the branches radiated outward from the ring line and adjacent ring lines. In addition, the impact on rail transit network after multiple stations fail simultaneously depends not only on the importance of each station, but also on the spatial location distribution of each station in the rail transit network.

Key words: redundancy, urban rail transit, key stations, complex network, station failure
