Abstract

The passenger flow at stations are stochastic and even a good timetable will cannot cope with its stochastic variation. To efficiently use the timetable, this paper proposes a regulation approach for train operation. For the scenario with a small passenger flow, the dwell time will be shortened according to the number of boarding and alighting passengers. The reduced dwell time will be added to the running time for the next interval such that the energy consumption of this interval will be reduced with a longer running time which implies a lower running grade in urban rail. Starting with the investigation of the invalid dwell time, the running time of different running grades is determined by assigning the buffer time to intervals to minimize the total energy consumption of a cycle time. Based on the operational data, a case study for Beijing Yizhuang line is presented to illustrate the effectiveness of the proposed approach.
以北京地铁为例的列车节能调控方法
车站客流是随机的,即使是一个好的时刻表也无法应对其随机变化。为了有效利用列车时刻表,本文提出了列车运行的调控方法。对于客流量较小的场景,根据上下客的数量,缩短停留时间。减少的停留时间将添加到下一个区间的运行时间中,这样,随着运行时间的延长,该区间的能耗将减少,这意味着城市轨道交通的运行等级较低。从无效停留时间的研究开始,通过分配缓冲时间来确定不同运行等级的运行时间,以最小化一个周期时间的总能耗。以北京亦庄线为例,分析了该方法的有效性。
