This study investigates a flexible marshalling mode to address the pronounced temporal-spatial imbalance of passenger flows in urban rail transit, achieve a more precise matching between supply (capacity) and demand (ridership), and thereby reduce operating costs. A comprehensive analysis is conducted on the current state of research on flexible marshalling, its passenger-flow adaptability, and engineering implementation requirements; using Qingdao Metro Line 5 as a case, the study further structures the online coupling/decoupling workflow and examines train operation routing design, fleet allocation strategy, track layout requirements, capacity evaluation, and life-cycle operational economic benefits. Results show that online coupling/decoupling is best located within the track arrangement zones of turnback terminals and junction stations, and that configuring terminals with paired turnback sidings increases turnback capacity. Additional capital expenditures attributable to the flexible mechanical marshalling mode are dominated by rolling stock and signalling systems, which together account for approximately 90%; it is therefore recommended that civil works reserve the necessary interfaces (e.g., for track layout adjustments and platform screen doors) during initial construction. Compared with an all-6-car fixed formation baseline, a mixed operation pattern comprising conventional 6-car fixed formations and 3+3 flexible coupled sets yields superior cost effectiveness through notable reductions in traction energy consumption and maintenance costs; nevertheless, current deployment remains constrained by limited system capacity, higher marginal equipment investment, and increased operational management complexity, all requiring further optimization. The findings provide a technical and organizational reference for designing train operation schemes on comparable urban rail lines.

为解决城市轨道交通线路客流时空分布不均衡问题,实现运力与运量的精准匹配,有效降低运营成本,对灵活编组模式进行研究。全面分析灵活编组研究现状、客流适应性及工程实施技术要求,并以青岛地铁5号线工程为研究对象,梳理在线解编联挂作业流程及该模式下行车交路设计、列车配属方案、配线设置、能力计算及运营经济效益分析等内容。研究结果表明:灵活编组作业地点宜在交路折返站、出入线接轨站配线区,折返站宜按双折返线布置以提高折返能力;灵活编组技术所额外增加的工程投资,以车辆和信号系统为主,占比约90%,建议建设期优先预留配线、站台门等技术条件;相较于常规6辆固定编组方案,采用6辆固定编组和3+3灵活编组混跑方案更加经济适用,在牵引能耗、维护费用方面节省明显,但现阶段该技术存在系统能力受制约、设备投资增幅较大、运营管理复杂等问题,还需进一步优化。研究结果可以为类似线路的行车组织方案设计提供参考。

为解决城市轨道交通线路客流时空分布不均衡问题,实现运力与运量的精准匹配,有效降低运营成本,对灵活编组模式进行研究。全面分析灵活编组研究现状、客流适应性及工程实施技术要求,并以青岛地铁5号线工程为研究对象,梳理在线解编联挂作业流程及该模式下行车交路设计、列车配属方案、配线设置、能力计算及运营经济效益分析等内容。研究结果表明:灵活编组作业地点宜在交路折返站、出入线接轨站配线区,折返站宜按双折返线布置以提高折返能力;灵活编组技术所额外增加的工程投资,以车辆和信号系统为主,占比约90%,建议建设期优先预留配线、站台门等技术条件;相较于常规6辆固定编组方案,采用6辆固定编组和3+3灵活编组混跑方案更加经济适用,在牵引能耗、维护费用方面节省明显,但现阶段该技术存在系统能力受制约、设备投资增幅较大、运营管理复杂等问题,还需进一步优化。研究结果可以为类似线路的行车组织方案设计提供参考。

This study investigates a flexible marshalling mode to address the pronounced temporal-spatial imbalance of passenger flows in urban rail transit, achieve a more precise matching between supply (capacity) and demand (ridership), and thereby reduce operating costs. A comprehensive analysis is conducted on the current state of research on flexible marshalling, its passenger-flow adaptability, and engineering implementation requirements; using Qingdao Metro Line 5 as a case, the study further structures the online coupling/decoupling workflow and examines train operation routing design, fleet allocation strategy, track layout requirements, capacity evaluation, and life-cycle operational economic benefits. Results show that online coupling/decoupling is best located within the track arrangement zones of turnback terminals and junction stations, and that configuring terminals with paired turnback sidings increases turnback capacity. Additional capital expenditures attributable to the flexible mechanical marshalling mode are dominated by rolling stock and signalling systems, which together account for approximately 90%; it is therefore recommended that civil works reserve the necessary interfaces (e.g., for track layout adjustments and platform screen doors) during initial construction. Compared with an all-6-car fixed formation baseline, a mixed operation pattern comprising conventional 6-car fixed formations and 3+3 flexible coupled sets yields superior cost effectiveness through notable reductions in traction energy consumption and maintenance costs; nevertheless, current deployment remains constrained by limited system capacity, higher marginal equipment investment, and increased operational management complexity, all requiring further optimization. The findings provide a technical and organizational reference for designing train operation schemes on comparable urban rail lines.
