深圳市地铁网络出行效率及运行可靠性研究

Travel Efficiency and Operational Reliability of Shenzhen Metro Network

为了研究深圳市地铁网络的特点,对深圳市地铁网络建立基于复杂网络理论的L空间网络模型。通过对地铁网络站点间非直线系数的分析,发现深圳市地铁网络站点间非直线系数偏大,出行效率一般。通过对网络全局效率、网络极大连通子图等度量指标的分析,发现当发生随机事件和特定事件时,深圳市地铁网络的网络全局效率和网络极大连通子图比例分布均服从指数分布,说明深圳市地铁网络整体表现为脆弱性,但当少量站点发生随机事件时,地铁网络又具有鲁棒性。研究表明,深圳地铁网络在后续建设运营时,可在一定程度上提升地铁出行的便捷性和可达性,同时继续保证重要车站运行的稳定性和可靠性。

In order to study the characteristics of Shenzhen metro network,established L space network model for Shenzhen metro network based on complex network theory.By analyzing the nonlinear coefficient between the stations of the Shenzhen subway network,it is found that the nonlinear coefficient between the stations of the Shenzhen subway network is too large and travel efficiency is average.By analyzing the metrics such as the global network efficiency and the network maximal connected subgraph,it is found that when random events and specific events occur,the global network efficiency and the proportional distribution of the network maximal connected subgraph of the Shenzhen Metro network obey the exponential distribution,indicating that the overall Shenzhen metro network is vulnerable.However,when random events occur at a few stations,the subway network is robust.According to the study,Shenzhen subway network can improve the convenience and accessibility of subway travel to a certain extent in the subsequent construction and operation,and continue to ensure the stability and reliability of the operation of important stations.
