    摘要:

    快慢车模式下,恰当的越行有助于提高市域轨道交通线路通过能力,但并非所有车站都具备越行条件。为定量把握线路通过能力与包含站型组合在内的众多因素的关系,提出一种线路通过能力计算方法。在掌握各站站型、列车停站方案、列车区间运行时分、列车间隔时间、快慢车开行次序,明确越行发生条件的基础上,按次序逐一引入快慢车,计算列车在每个车站的到发/通过时刻并及时调整被该列车越行的列车的运行时刻,之后引入下一列车,直至线路通过能力饱和。计算案例限定了设有到发线的中间站总数,结果表明,针对不同的快慢车开行比例,站型组合对线路通过能力均有影响,但影响程度不同。计算线路通过能力时应考虑到站型组合的约束。

    Abstract:

    With express and local trains in mixed operation mode, appropriate overtaking maneuvers can enhance the line carrying capacity of suburban rail transit systems; however, not all stations are equipped with overtaking facilities. To quantitatively analyze the relationship between line carrying capacity and multiple factors including station layout combinations, a line carrying capacity calculation method is proposed. Based on predefined parameters—station layouts, train stopping plans, train running times in sections, trains interval times, and express/local train scheduling priorities—and with the conditions for overtaking clearly defined, the method sequentially introduces express/local trains, calculates arrival/departure or passing times of each train at each station, dynamically adjusts timetables of overtaken trains, and iterates until line carrying capacity saturation is achieved. Case studies with a fixed number of intermediate stations equipped with receiving-departure tracks demonstrate that station layout combinations universally affect line carrying capacity under varying express/local train ratios, but their impacts differ in magnitude. The results emphasize the necessity of incorporating station layout constraints into line carrying capacity calculations.
