【摘要】 近年来,随着我国城际轨道交通系统的快速发展,既有城际轨道交通的运输组织方法已经不再适用于新的线网条件。为了使城际轨道交通线网发挥整体作用,采用先进合理的运输组织和运营管理方法将成为现阶段城际轨道交通系统的研究重点,其中编制出符合城际轨道交通线网特征和客流特征的旅客列车开行方案更是重中之重。在制定旅客列车的开行方案时,首先要确定旅客列车的运行区段和列车对数,即确定列车交路。采用合理的列车交路,能在不降低服务水平的前提下提高车辆的运用效率,避免运能虚糜,使行车组织做到经济合理。本文着眼于跨线客流的运输组织问题,研究跨线列车的交路优化,以珠三角地区城际轨道交通线网结构特点和旅客出行需求为依据,同时兼顾铁路运输企业和旅客的利益,具有十分重要的理论和现实意义。本文的研究内容主要有以下几个部分:(1)珠三角城际轨道交通线网概况。首先结合珠三角城镇群的发展现状,分析珠三角城际轨道交通线网规划的内容,阐述了规划线网的结构特点和线路特征;接着对线网客运枢纽的布设进行分析,给定各城市主要客运站的平面示意图;最后对线网互联互通的方式进行分析,结合图示予以说明。(2)珠三角城际轨道交通线网节点层次划分。首先阐述线网节点的概念及选择范围,分析珠三角城际轨道交通线网的节点构成;接着综合考虑节点层次划分所涉及的各个因素,将线网节点的客运需求、线网属性、客运能力及政治经济影响等因素作为层次划分的主要依据;最后基于灰色关联决策的方法,对城际轨道交通线网的节点层次进行划分,并通过珠三角地区各城市指标资料的收集,得到城际轨道交通线网节点层次划分的结果。(3)珠三角城际轨道交通线网跨线客流的运输组织模式。首先对跨线客流运输组织模式的选择作一般性阐述,对主要影响因素进行分析,比较跨线客流两种输送方式的优缺点;接着分析线网条件下跨线客流运输组织模式,在跨线列车运行模式分析的基础上,研究不同等级节点间跨线客流的运输组织模式;最后通过珠三角地区实例分析予以说明。(4)珠三角城际轨道交通线网跨线列车开行优化研究。首先结合城际轨道交通动车组运用检修特点,分析珠三角城际轨道交通线网动车组运用检修设施布局;接着基于传统的“按流开车”原则和动车组运用维修需要,确定跨线列车交路的两端站点;最后以旅客列车的运行费用最小与旅客的旅行时间最短为优化目标,建立数学规划模型,对跨线列车的运行径路进行优化,并采用蚁群算法求解。并以珠三角城际轨道交通线网为例,得到跨线列车径路优化的结果。
【Abstract】 In recent years, with the rapid development of intercity rail transit system in our country, the existed intercity rail transportation organization methods are no longer suitable for the new network condition. In order to let intercity rail transit network play an integral role, adopting advanced and reasonable transportation organization and operation management methods will be the research focuses of intercity rail transit system at the present stage, among which working out the passenger train operation plan consistent with intercity rail transit network features and passenger flow characteristics is the most important.In the progress of working out the passenger train operation plan, firstly we should determine the running sections and the number of passenger trains in pairs, that is determining the train routing. Adopting reasonable train routing could improve vehicle utilization efficiency without reducing the service level, avoid traffic capacity waste, and make the traffic organization economical and reasonable.

Then, based on the comprehensive consideration of the various factors involved in the node level division, adopting the passenger transport demand, the network characteristics, the passenger transport capacity, and the political and economic influence as the main basises. Finally, based on the grey correlation decision making method, the paper carries on the division of the intercity rail transit network node level, and through the collection of the Pearl River Delta urban indicator datas, obtaining the node level division results of the intercity rail transit network.(3)Studying on the cross-line passenger transport organization mode of the Pearl River Delta intercity rail transit network.
