城市轨道交通潮汐客流与运能匹配的多交路运输组织方案研究

Multi-Routing Transportation Organization to Match Tidal Flow of Passengers and Transportation Capacity in Urban Rail Transit

城市轨道交通网络中的客流存在着规律性的动态变化,其中最为明显且突出的是由于居民通勤通学的出行需求所带来的潮汐交通现象。在潮汐交通现象较为明显的线路中,客流存在着时间与空间上的不均衡分布,使得部分区间的运能未得到充分利用或者部分区间的运能紧张。据此,本文以成都地铁1号线为例,针对其潮汐客流特征展开研究,识别运能不足或运能过剩的区间,并建立多目标优化模型求解出针对具体线路的多交路运输组织优化方案,最后对优化方案的效果做出评价。

The passenger flow has some regular changes,of which the most distinct phenomenon is tidal flow at peak hours because of commuting passengers.The distribution of passenger flow in the lines which has distinct tidal transit is uneven both in time and in space.Thus,some sections of the line is short or waste of transportation capacity.In order to match tidal flow of passengers and transportation capacity,this paper takes Chengdu Metro as an example,studying on its characteristics of passengers’tidal flow to find which are weak and overloaded sections in line,aiming them to set up a multi-objective model to get an optimal short-and long-range transit planning,and then evaluating the effect of that planning.
