随着城市轨道交通线路由市区逐渐向外围拓建与延伸，市域快线的规划与建设应运而生，如何合理选择市域快线运营模式成为目前需要研究和解决的问题。以成都地铁13号线为依托，分析穿城市域快线的客流特征，基于客流需求、城市布局、大区客流分布、客流断面特征，对行车对数和大小交路折返点进行系统研究，确定地铁13号线的行车对数并提出3个行车组织方案。并从运能适应性、高峰小时车公里、最大满载率、运营组织难易度等关键指标方面进行对比分析，确定最佳运营方案，以期为类似穿城市域快线运营模式的合理选择提供借鉴和参考。

With the gradual expansion and extension of urban rail transit lines from urban areas to the periphery, the planning and construction of urban express lines have emerged as the times require. How to choose reasonably the urban express line operations mode has become a problem that needs to be studied and solved. Based on Chengdu Metro Line 13, the passenger flow characteristics of the “through-the-city” urban express lines were analyzed. Based on passenger demand, urban layout, distribution of regional passenger flow, and characteristics of passenger flow section, a systematic study was made of the number of trains and turning points of large and small intersections. Three traffic organization schemes were put forward, and the optimal operations scheme is determined by comparing and analyzing the key indicators, such as capacity adaptability, peak hour vehicle kilometers, maximum full load rate, and operational organization difficulty. The study is expected to provide reference for the reasonable selection of the operation mode for similar “through-the-city” urban express lines.
