成都市二环路改造规划的研究方法

The Research Methodology in Chengdu 2nd Ring Road Reconstruction Planning

《成都市二环路改造规划研究》在同类工作中有4个创新:理念创新、研究方式创新、评价体系创新和公交方式创新。采用了目标体系研究、专题研究、方案研究及成果研究四段式的研究方式,其中,目标体系研究锁定二环路改造的4类18项目标并给出权重;专题研究确定了6个基础性的研究课题;方案研究中根据通行能力、车速、公交等方面的差异划分了3类方案,进行技术经济、社会效益全面比选评价;成果研究则对选定方案进行优化、深化及完善。评价方法采用了居民意愿调查、本地各部门对方案的评价及打分、方案技术比较、方案社会经济效益综合比较、专家评价及打分和行政决策。

The Study for Chengdu 2nd Ring Road Reconstruction Planning, compared with the similar projects, has four innovations which are mainly in planning concept, research method, evaluation method and introduction of Bus Rapid Transit(BRT). The research methodology has four-step process: study for goals system, special topics, draft planning and final planning. The goal system research locks goals in four sorts and eighteen sub-sorts and gives all factors different weights to evaluate. The research for special topics covers six foundational subjects in final reports. During the process of draft planning, according to road capacity, the vehicle speed and public transportation system, three sorts of draft plans were received, which had been compared not only based on the technical standard, but also on project cost and social benefit balance. In the final planning the best draft plan had been deepen and optimized. Besides, the evaluation method includes the citizen investigation, consultation to local executive departments, expert evaluation and weighting and administrative decisions.
