摘 要: 常态高峰下,客流在线路的累积传播造成部分时空点列车满载率过高,需要采用客流流入联合控制的手段,以缓解尖峰客流压力。从路网和客流交互的物理机理出发,提出轨道交通线路客流拥挤传播模型。借助模型分析单线客流拥挤传播的时空演变过程,以作为控制点识别的基础。提出线路客流流入控制的原则和确定流程,以及关联车站的客流流入调整量计算方法,结果能够保证所有时空点满载率在合理水平以下。以早高峰北京地铁1号线苹果园至公主坟区段为例,表明本文提出的模型能够掌握常态高峰单线客流拥挤传播的时空演变过程和特征,客流流入控制的计算结果能够为限流策略制定提供量化依据。

Abstract:In peak hours, passenger flow accumulate and propagate along the urban rail transit lines, which make the load factors excessive for some space-time points. It is necessary to take cooperative passenger flow control measures to release passenger pressure for some peak points. Firstly, based on the interaction mechanism between passenger flow and transit network, a congestion propagation model for urban rail transit lines is established. Then, temporal-spatial erosion process is studied through the model and control points are figured out. Lastly, principles, steps of passenger flow control and calculation method of adjustment values for the related stations are put forward. An example is made of the section from Pingguoyuan to Gongzhufen of Beijing Subway line 1, showing that the model can effectively analyze the evolution process and the characteristics of passenger flow propagation in peak hours, and that the numeric results of passenger flow control can be quantitative basis for passenger flow control policies.

 

Key words: urban rail transit line; peak hour; congestion propagation; passenger flow control
