大城市城市轨道交通线网规划关键技术探讨

目前,城市轨道交通线网规划的技术已相对成熟,指导了我国超大、特大城市的城市轨道交通建设。随着城市化进程的不断加快,人口在100万至500万的大城市已成为城市轨道交通规划和建设的重要参与者。大城市在空间、人口、经济、交通出行特征等方面与超大、特大城市存在较大的差异,使得目前城市轨道交通线网规划的技术对大城市的适用性存在一定的局限。通过分析大城市与城市轨道交通的互动关系,提出大城市城市轨道交通线网规划的需求。基于现有的城市轨道交通线网编制技术流程,结合大城市的需求,从前提研究、方案研究、实施规划三个层面,对城市轨道交通线网规划编制中服务范围分析、线网规模确定、近期建设方案制定等技术内容提出优化建议,以适应大城市城市轨道交通线网规划的编制需求。

Discussion on Key Technologies of Urban Rail Transit Network Planning of Large Cities

At present, the technology of urban rail transit network planning has been relatively mature, which guides the construction of urban rail transit in super large cities. With the acceleration of urbanization, large cities with a population of 1 million to 5 million have become important participants in urban rail transit planning and construction. Due to the great differences in space, population, economy and travel characteristics of super large cities, the applicability of urban rail transit network planning technology in large cities is limited. Through analyzing the interaction between large cities and urban rail transit, the demand of urban rail transit network planning of large cities is proposed. Based on the existing technical process of urban rail transit network compilation and combined with the needs of large cities, this paper puts forward optimization suggestions on service scope analysis, network scale determination and recent construction plan formulation from the aspects of premise research, scheme research and implementation planning so as to meet the compilation needs of urban rail transit network planning of large cities.
