天津轨道交通复杂网络和应急选址研究

Complex Network and Emergency Site Selection of Tianjin Rail Transit

天津已逐步形成轨道交通网络化运营模式,但各线路间的应急管理相对独立、协同性差,导致应急资源利用效率低,应急响应不及时。建立基于11条天津轨道交通线路的复杂网络模型,对其进行统计特性分析,开展车站站点失效的脆弱性研究。在考虑需保护的脆弱站点的基础上,建立适用于天津轨道交通网络化运营条件下的应急设施中心选址模型,确定应急设施中心共计26个,同时明确其覆盖范围。选址结果可提高未来线网的应急效率,其分析过程适用于其他轨道交通网络。

Tianjin has gradually formed a network operation mode of rail transit, but the emergency management of each line is independent and poorly coordinated, resulting in low efficiency of emergency resource utilization and delayed emergency response. A complex network model based on 11 Tianjin rail transit lines is established, statistical characteristics are analyzed,and the vulnerability to station failure is examined. Based on the vulnerable sites to be protected, a site selection model for emergency facility centers suitable for the networked operation of Tianjin rail transit is established, 26 emergency facility centers are identified, and their coverage is clarified. The site selection results can be used to improve the emergency efficiency of future network operations. The analysis process is also applicable to other rail transit networks.
