重庆渝利线市郊列车通勤化开行方案

Suburban Train Commuting Operation Plan in Chongqing-Lichuan Railway

重庆具有典型的组团特征,利用既有铁路开行市郊列车能够有效缓解重庆主城区的交通压力。从开行数量、开行时段、停站情况三个方面分析了渝利线市郊列车的开行现状,给出了全日站间客流表及客流密度,以确定市郊列车的开行区段及数量。在现有列车开行方案基础上,根据渝利铁路沿线市郊客流的需求进行了改进,即在6:00~21:30,分别开行3.5对"重庆北—涪陵北"区段、7对"重庆北—石柱县"区段的站站停市郊列车,并在早晚高峰时段,增加市郊列车开行频率。相对于现有列车开行方案,改进的方案方便乘客记忆,且能够保证乘客出行的便利性。

Due to the assembly characteristics in Chongqing＇s railway system, the suburban rail operations based on the existing railway infrastructure can effectively alleviate the traffic pressure in the main urban areas of Chongqing. The current situations of suburban trains in Chongqing-Lichuan railway are analyzed from three aspects, i.e., train quantities, operation times and stopping scenarios. As a result, a new full-time passenger flow model between stations and terminals is proposed to optimize the number of operational sections and suburban train trips. The original train operation plan is improved by considering the real-time demands of suburban passenger flow along the Yu-Li corridor. In the improved schedule, 3.5 pairs of train trips on the Chongqingbei-Fulingbei section and 7 pairs of train trips on the Chongqingbei-Shizhuxian section can be added to meet the realistic demands of suburban passenger flow during the period from 6：00 to 21：30, and to increase the operation frequency of the suburban trains in the morning and evening peak times. In comparison to the original plan, the improved plan can provide better service for the railway commuters.
