无锡地铁5号线车辆编组方案

Vehicle Formation Scheme for Wuxi Metro Line 5

[目的]为一定程度解决中等线网规模的城市轨道交通运营满载率偏低、运营成本高、过分依赖政府财政补贴的问题,以无锡地铁5号线为例,开展基于运营线路实际客流研究新线车辆的编组方案。[方法]通过从既有线采用6辆编组的实际客流情况出发,结合景区突发大客流的潜在影响,首先对无锡地铁5号线远期编组方案进行研究,确定土建规模,其次再通过对初近期采用4辆编组和“3+3”联挂方案进行比选,分析25年的运营成本和购置费。[结果及结论]研究结果表明:在基于实际客流和突发大客流的考量下,明确土建按6辆编组实施,初、近期采用3辆、4辆小编组以提高服务水平,初、近期“3+3”联挂方案运行效率和灵活性更高,但目前实际应用案例较少,技术成熟度有待进一步考量,最终推荐采用初期4辆编组,在提高服务水平的同时可提升满载率和客运量。

[Objective]To somewhat address the issues of low passenger load factor,high operating cost,and excessive reliance on government subsidies in medium-sized urban rail transit network,taking Wuxi Metro Line 5 as example,a formation scheme of new line vehicles is developed based on the actual passenger flow on operating lines.[Method]Starting from the actual passenger flow of the existing lines using 6-car formation and considering the potential impact of sudden large passenger flow in the scenic spot,the long-term formation scheme for Wuxi Metro Line 5 is first investigated to determine the civil engineering scale,and then the 25-year operating cost and purchase cost are analyzed by comparing the initial and recent adoption of a 4-car formation and the′3+3′coupled formation schemes.[Result&Conclusion]Research results indicate that,based on the consideration of actual passenger flow and sudden large passenger flow,it is recommended to implement civil engineering according to a 6-car formation.In initial and short terms,the 3-car and 4-car formations shall be adopted to enhance service level,and the′3+3′coupled formation scheme can offer higher operating efficiency and flexibility,but its practical application cases are limited and the technological maturity needs further estimation.Therefore,it is ultimately recommended to adopt a 4-car formation for the initial term,which can improve service level while increasing passenger load factor and passenger volume.
