摘要：随着我国城镇化进程的加速，继特大、超大城市之后，众多IⅡI型大城市加入城市轨道交通的规划、建设行列。分析城市特征和国家政策，认为ⅡI型大城市更适合发展中运量的轨道交通系统。对比国内各类中运量轨道交通系统的发展现状，筛选出Lb型车、高地板C型车、70%低地板C型车、跨座式单轨共4种拥有独立路权、以交通功能为主的轨道交通系统供IⅡI型大城市选择。从服务水平、道路适应性、环境适应性、系统拓展能力4个方面分析备选系统与II型城市的适应性。认为Lb型车和高地板C型车的单位运输效率较高，Lb型车和70%低地板C型车的道路和环境适应能力较强，高地板C型车和70%低地板C型车网络化运营优势明显。以上4类系
统能满足国内绝大多数ⅡI型大城市的交通需求，具体选型需结合城市特征和工程条件进一步分析。关键词：城市轨道交通：II型大城市；系统选型；中运量轨道系统

Abstract: With the acceleration of China's urbanization, cities with an urban population of 1 to 3 million (Type II megacities) have started to plan or build their urban rapid transit systems. Considering the commonly acknowledged population threshold eaaeeaaaaeessea provide a medium capacity (5,00015,000 ridership per hour) and operate as arterial traffic corridors with exclusive right-of-way are more suitable for Type II megacities. Available systems include Type Lb vehicles, high-floor type C vehicles, 70% low-floor type C vehicles, and cross-saddle monorail. A suitability study of these four systems is conducted herein from the aspects of service level, adaptability to various roadway conditions, adaptability to different kinds of environment, and
are also suggested: Type Lb and high-floor Type C
potential for nctwork expansion. The following com

vehicles have a higher capacity; Type Lb and 70% low-floor Type C vehicles perform better in different roadway and environment conditions; and high-floor Type C and 70% low-floor Type C vehicles are easier to operate in a network. In summary, the four types of medium-capacity urban rail transit system are potential options for most Type II megacities, A
further analysis on the mode selection should be made based on city shapes and specific engineering conditions Keywords: urban rapid transit systems; Type II megacities; vehicle selection; medium capacity transit systems
根据2014年国务院下发的《关于调整城市规模划分标准的通知》，我国按城区常住人口规模将城市划分为五类七档，其中100万～300万人口的城市为IⅡI型大城市；300万～500万人口的城市为1型大城市；

500万～1000万人口的城市为特大城市：1000万以上人口的城市称为超大城市。
依此标准，我国现阶段开通城市轨道线线路的多为超大城市、特大和I型大城市，该类城市空间尺度大，居民出行强度高，故采用大、高运量地铁制式的比例较大。统计数据表明，2016年末内地运营的轨道线路中地铁线路占总里程数的83.95%]
实际运营情况表明，以高标准、高投入获得大客
