【摘要】 面向城市连绵地区构建与之适应的轨道交通系统,关键在于提供具有针对性的服务层级,满足区域范围内不同的出行需求,应对出行链的复杂性和多样性。从城镇群、都市区、中心城市三个层面分析城市连绵地区的典型空间形态,并探讨与之对应的城际出行、城郊出行、城市内部出行活动特征。提出构建差异化的轨道交通层级,即区域轨道交通、市域轨道交通、市区轨道交通,重点探讨各个层级轨道交通的构成、作用、线路技术特征等,以及不同层级的衔接关系。更多还原

【Abstract】 To develop effective rail transit system in megalopolises,it is important to establish a clear service hierarchy to meet travel demands within different regions with comprehensive and diversified characteristics of trip chains.By analyzing the typical spatial structure of megalopolis at three levels: urban cluster,metropolitan area,and major city,this paper discusses the corresponding characteristics of intercity travel,travel in suburban areas and within cities.Then the paper proposes a service hierarchy of rail transit including regional rail,metropolitan railway,and urban rail transit.The paper also elaborates the component,functionality,and technology characteristics of different rail transit levels,as well as the connection between the three levels of rail transit.更多还原
