论城市轨道交通线网规划修编的前期研究

Early-Stage Study on Urban Rail Transit Network Planning Revision

从目前城市轨道交通线网规划不断调整的趋势出发,说明在线网规划中对前期的战略性研究存在不足。结合《重庆市轨道交通发展纲要(2011—2020)》的编制,探讨对线网规划修编进行前期研究的作用、内容和研究方法,指出:前期研究是指导调整线网规划和建设规划的纲领性文件,需要在"目标-实施一体化"的框架内,重点探讨轨道交通线网发展的目标、战略途径、重大行动和保障体系;应采取"系统分析+意愿分析"论证轨道交通的发展目标,以多元化的效率目标来综合审视线网规模,以"两个一体化"(轨道交通与城市空间一体化、轨道交通与其他交通方式一体化)来统筹线网形态布局。

The current tendency of continuous adjustment of urban rail transit network planning indicates that some problems have been existing in the earlier-stage strategic study of network planning. Considering the revision of ＂Chongqing Rail Transit Development Outline （2011--2020）＂, the role, contents and research methods were discussed for the early-stage study on network planning revision. It has been shown that early-stage study is a guideline for the adjustment of network planning and construction plan. The development objectives, strategic approaches, major actions and security system of urban rail networks should be implemented under the framework of ＂integrating the target with implementation＂. The ＂system analysis ＋ wish analysis＂ method should be adopted to verify the rail transit development targets. A wide range of efficiency targets should be used to examine transit network scales in an all-round way. The layout of the urban transit network should be based on the integration of rail with other traffic modes as well as the integration of rail transit with urban space.
