我国城市轨道交通处于快速发展时期，市域轨道作为城市轨道交通的重要组 成部分，因其在解决市中心居民过分集中、改善居住条件、发展卫星城镇等方面 的战略导向功能，在大城市轨道线网规划建设中方兴未艾。然而开通的市域轨道 线路上运营中屡次出现列车开行方案不能满足市域客流出行需求的问题，究其原 因，主要是因为市域轨道规划过程中，未能充分考虑列车运输组织的多样性以及 列车运输组织对线网规划方案的要求，从而导致运营阶段出现市域线网形式制约 列车开行方案的制定的情况。如何把列车运输组织融入市域轨道交通规划，建立 一套适合我国市域轨道线网规划的流程是本文研究的主要目的。
把考虑列车运输组织影响的市域轨道交通规划归结为两个"匹配"问题：一、 列车开行方案与市域轨道客流出行需求相互匹配；二、规划线网设计通过能力与 列车开行方案的通过能力需求相互匹配。第一个匹配在"根据客流需求确定列车 开行方案"章节中求解，第二个匹配分三个步骤求解，分别为"构建乘客换乘网 络"、"开行方案和线网设施服务水平评价"和"线网设施建设"。
对结合列车运输组织的市域线规划流程进行了梳理和探讨。从预测客流OD 出发，结合市域轨道客流特征，根据乘客需求确定市域轨道列车开行方案；通过 乘客换乘网络的设计，以及在换乘网络上进行公交客流分配，以掌握乘客在列车 及线网上的分布；通过多方面多个评价指标的计算，对列车开行方案和线网设施 服务水平进行综合评价；结合评价指标和借鉴国外市域轨道建设经验，提出市域 轨道设施的建设要求。
在城市轨道交通线网规划报告中，对列车开行方案的评价目前仅限于区间运 能与运输需求的满足程度指标，本文建立了开行方案和线网设施服务水平评价指 标结构，并计算得出多项评价指标，补充了列车开行方案评价指标，有利于全面 评价列车开行方案服务水平。
本文对线网的衔接、线网区间的布置、车站配线的设置三方面提出了建设要 求。其中包括，从与城市轨道交通线网的衔接形式、合理的站间距大小、换乘站 的同站台换乘设计、越行站和折返站的配线形式等方面给出了市域轨道建设原 则、推荐指标、以及能力优化步骤。弥补了我国市域轨道由于建设标准缺失而导 致轨道形式和制式不统一的缺陷，为市域轨道的规划建设提供参考依据。
As one of the most important part of urban mass transit which is developed quickly in China, suburban rail has been noted for its strategy oriented function that is to release the high density of downtown, to improve living condition, and to develop new towns. However, on the newly built suburban rail network, we confront a common problem that train operation plans which were made during the operational period can not satisfy the travel demand of suburban passengers very well. The reason for this is that the diversity of transportation organization scheme and its requirement to rail network was not well considered during the suburban rail planning process, so that train operation plan was restrict by the forms of suburban rail network in operational process. How to combine transportation organization scheme with suburban rail planning, to build a reasonable planning process for China suburban rail is the main research aim of this paper.
On the basis of Passenger flow characteristics, and the feasibility of skip-stop
transportation organization scheme, with the help of operation plan from different
fields, to satisfy the travel demand of suburban passengers, four kinds of train
operation plans was determined. Within them, the first train operation plan includes
all stop by stop trains; the other three plans include stop by stop trains mixed with
In order to evaluate the service level of train operation plans and infrastructure
comprehensively, we need to obtain the passenger flow distribution and construction
on the sections and stations in the suburban rail planning process, so passenger
interchange network were construct on the basis of train operation plan and stop plan.
Transit Equilibrium Assignment (UE model) was carried out on the passenger
interchange network. With the help of software TRANSCAD, the passenger flow
distribution and construction on the sections and stations was obtained, and these data
serve as basis for evaluation of train operation plans and infrastructure.
Service level evaluation index system of train operation plan and infrastructure
was built, and evaluation index were categorized according to three factors, as
satisfied level of passenger transport demand, stability of timetable, utilization of
infrastructure carrying capacity. Based on the data of passenger flow distribution, with the method of statistic analysis, the software simulation, and timetable planning, such
indices as maximum section flow, saturation of sections, passenger flow of stations,
average on-board time, transport efficiency, maximum OD to accommodate,
maximum train path to insert into timetable, carrying capacity utilization of
infrastructure, reserved capacity of network were calculated.
To meet the carrying capacity requirement of transportation organization scheme
to suburban rail network, consider the evaluation indices of train operation plans and
infrastructure, facilitate passenger interchange and improve or optimize carrying
capacity of the whole transport system, suburban rail network construction without
engineering restrictions was studied. Here we mainly stress on corridor design and
station design. In the corridor design part, the effective junction forms and reasonable
distance between stations were researched; and in station design part, the number of
sidings, platform setting and capacity optimization process of transfer stations,
overtaking stations and turn-back stations.
Main achievement of this paper:
(1) Solving two "match" problems
Suburban rail planning process with the factors of transportation organization was concluded into two "match" problems: first, to match train operation plans with travel demand of suburban passenger flow; second, to match the carrying capacity of designed network with the carrying capacity requirement of train operation plans. The first "match" problem was solved in the Chapter 3; while the second "match" problem was divided into 3 steps, and was solved in Chapter 4, 5 and 6 respectively.
(2) Providing a reasonable planning process for China suburban rail
First, based on the forecast passenger OD, and the travel characteristic of suburban passenger flow, train operation plan was designed; second, with the distribution data on the passenger interchange network, the service level of train operation plans and infrastructure was evaluated comprehensively; third, with the help of evaluation index and construction experience of suburban rail in other countries, the construction requirements of China suburban rail infrastructure in planning process were made.
(3) Increasing the evaluation indices of operation plan
In the report of suburban rail reasonability study, the evaluation index recently is only limited to the comparison between the supplied capacity with the travel demand in the sections. So the service level evaluation index system of train operation plan and infrastructure which was built, and the evaluation indices which were calculated facilitate the service level evaluation of train operation plans in practice.
(4) Supplying the construction standard of suburban rail infrastructure
Three factors as effective junction forms, the distribution of sections and station settings were studied, within which the standards or principles of the network connection to urban mass transit, the distance between stations, cross-platform transfer design, the siding setting of overtaking stations and turn-back stations were suggested. These data will serve as construction standards in suburban rail planning, and help to revise the discordant of suburban rail network due to the missing construction standards before.
