摘要

在轨道交通市郊线路,快慢车的开行可以很好地适应市郊客流在时空分布上的差异性,但由于采用了非平行运行图,快慢车比例、越行站的分布和数量、列车发车间隔等因素,都对线路通过能力产生不同程度的影响.为研究快慢车模式下线路通过能力随不同参数演变的影响机理与内在关系,提出了快慢车模式下通过能力的计算思路,对不同越行次数、快慢车开行比例下通过能力的计算与表达进行了分析,并通过算例进行验证,为市郊线路快慢车模式下通过能力的计算提供了理论参考.
        In suburban rail transit line, the operation of fast-slow trains can be well adapted to uneven spatial and temporal distribution of the passenger flow. However, due to the use of non-parallel operation diagram, the proportion of fast and slow vehicles, the distribution and quantity of the overtaking station, the interval of train departure and so on, all have different influence on the carrying capacity of the line. In order to study the influence mechanism and internal relationship of carrying capacity with different parameters of suburban line under fast-slow mode, a calculation idea was put forward, and then the calculation and expression of the carrying capacity was established by considering the quantity of overtaking and the proportion of fast and slow vehicles. Shanghai Metro Line 16 being taken as an empirical study, the proposed methods were proved effective. This study results contribute to a theoretical reference for the calculation of the carrying capacity of suburban line under fast-slow mode.
