基于费用效果分析原理,以某市内环快速路与外环高速公路之间放射线快捷化改造方案为例,研究了项目经济性、社会影响、区域交通组织及施工便利性等因素对方案设计的影响,以求为类似项目提供参考。研究认为,仅以项目本身功能实现为前提进行费用效果分析,存在较大的风险,项目社会影响等也是一票否定方案的因素;区域总规划对项目方案选择起到了决定性作用;方案设计中应保证主要交通流通行效率和次要交通流的可通达性。
Based on the principle of cost-effectiveness analysis, this paper takes the rapid reconstruction project of radiation between Inner Ring Expressway and Outer Ring Expressway as an example to study the influence of project economy, social influence, regional traffic organization and construction convenience on the design of the scheme Influence, in order to provide a reference for similar projects. According to the research, the cost effectiveness analysis based on the realization of the project itself has great risks and the social impact of the project is also a factor of negative vote. The regional general plan plays a decisive role in the selection of project options. To ensure the main traffic flow efficiency and accessibility of secondary traffic flow.
