基于扣除系数的快慢车模式下线路通过能力计算

Calculation of Line Passing Capacity under Express/Local Mode Based on Removal Coefficient

快慢车组合运行可以较好地适应市郊线路客流在时空分布上的不均衡性。为研究快慢车模式下各因素对通过能力的影响机理,结合快慢车模式运输组织的自身特点以及扣除系数法的思想本质,定量给出了不同条件下各因素对通过能力的扣除系数取值,提出了基于扣除系数的快慢车模式下的市郊线路通过能力计算方法。以上海轨道交通16号线为例,对不同越行次数、越行地点和停站地点等因素下的通过能力进行了计算分析。

The combined operation of express/local trains can better adapt to the unbalanced spatial-temporal distribution of passenger flow on suburban lines.In order to study the mechanism of various factors influencing the passing capacity under express/local mode,considering the characteristics of express/local mode transport organization and the ideological essence of removal coefficient method,the removal coefficient value of each factor of the passing capacity in different conditions under express/local mode are quantitatively presented.A calculating method of suburban line passing capacity under express/local mode based on removal coefficient is proposed.Taking Shanghai Rail Transit Line 16 as an example,the passing capacity with factors including different quantities and locations of overtaking is calculated.
