城市轨道交通环线客流特征分析及启示

Passenger Flow Characteristics Analysis of Urban Rail Transit Loop Lines

轨道交通环线在轨道交通网络中具有特殊的地位和作用。首先,通过对比分析北京市、上海市轨道交通环线与非环线路的客流特征,总结出环线具有可达性较强、客运量高、断面客流量波动性较小、平均运距较短、换乘量较大等特征。其次,分析北京市第二条环线成环前后轨道交通线路客流特征变化、外环线路开通对内环线路的影响以及环线对于放射线路的分流作用,总结双环结构中内外环之间的关系及对放射线路的影响。最后,从轨道交通环线在线网中的功能、位置选择和建设时机等方面提出探索性建议。

Loop lines play a special role in urban rail transit network. By comparing the passenger flow characteristics of rail transit loop lines with non-loop lines in Beijing and Shanghai, this paper summarizes that loop lines have higher accessibility, larger passenger volumes, lower fluctuation in section volume, shorter average travel distance, and larger transfer volumes. Then the paper discusses the changes in passenger flow characteristics of rail transit lines before and after the formation of the second loop line in Beijing. By analyzing the impact of the outer loop line on the inner loop line as well as the diversion impacts of loop line on radial lines, the paper summarizes the relationship between the outer loop line and the inner loop line and the impacts on radial lines. Finally, the paper makes suggestions on the functionality in rail transit network, site selection and construction time for loop lines.
