基于三元不等式组的同台换乘能力分析方法研究

An Analysis Method for Cross-platform Interchange Capacity Based on Ternary Inequalities

针对城市轨道交通同台换乘站在应用现状和专家观点层面存在的供需不匹配问题,论文基于三元不等式组,提出了同台换乘能力的定量分析方法。首先,讨论了换乘能力的定义,提出了适用于同台换乘站的换乘能力分析模型。其次,分析了站台聚集乘客所占据的行人空间总和、站台有效容纳面积、站台上并联换乘通道的通过能力、垂直移动设施通过能力和列车车门通过能力等影响换乘能力的因素。最后,化简推导出基于三元不等式组的同台换乘能力计算方法,该方法可用于新建和改建换乘站。

Application status and experts’opinions indicate that there is mismatching between capacity and demand in crossplatform interchange stations of urban mass transit.Aiming to solve the problem,this paper proposes a quantitative analysis method of the cross-platform interchange capacity based on ternary inequalities.Firstly,the definition of interchange capacity is discussed in order to build a model for interchange capacity analyzing which is applicable for cross-platform interchange stations.Secondly,the influencing factors to interchange capacity including total pedestrian space occupied by the passengers gathered at the platform,effective accommodating area of the platform,capacity of parallel interchange passages on the platform,capacity of vertical transport facilities and capacity of train doors are analyzed.Finally,a computing methodology for interchange capacity based on ternary inequalities is deduced,which is applicable to both new and rebuilt interchange stations.
