网络条件下成都轨道交通13号线运营交路研究

Study on the Operation Routing of Chengdu Rail Transit Line 13 Under Network Conditions

城市轨道交通近年来发展迅猛,线路长度与形态复杂性增加、客流层次性丰富度提高、网络化运营推进,连接中心城区与外围区域的长大线路出现。其交路方案的选取应保证运能分配均匀、服务频率合理、满足客流需求。本文以成都轨道交通13号线为研究对象,阐述功能定位,对线路客流特征、速度目标、车辆选型与编组等相关运行计划进行分析与决策,在此基础上拟定五个备选交路方案。以客运服务质量、客运组织难易程度、行车组织可行性、行车组织安全性、建设与运营成本、远期发展能力为影响因素构建评价体系,选取成都轨道交通13号线最优交路方案。

Urban rail transit has developed rapidly these years,its trend mainly include following aspects:increasing line length and morphological complexity,increasing rich passenger flow hierarchy and promoting network operation.Long lines connecting central urban areas and peripheral satellite city are widely being constructed.Routing schemes should meet passengers’demand.The article explains functional positioning of Chengdu rail transit line 13,based on the analysis of related operational plans including passenger flow characteristics,speed targets,vehicle selection and marshalling,the article proposes five alternative routing operation schemes.Taking service quality,difficulty of passenger transport organization,safety and flexibility of the operation organization,construction and operation cost,long-term development ability into consideration,establish the evaluation system of operation scheme of Chengdu rail transit line 13.With a comparative study of the five schemes through analytic hierarchy process,the best operation routing scheme is proposed.
