道路改扩建工程交通导改问题研究

Traffic Route Altering Guidance in Reconstruction Project

依托京密路(太阳宫北街—机场南线)道路工程,采用对现况道路通行能力“占一还一”的导改原则,阐述了主线交通导改和关键节点交通导改中的各种情形,重点分析了交通导改方案设计时的方法与思路,并对交通导改难点问题进行了总结和分析,提出了优化施工空间、交通空间和减少导改时间等各项解决思路,可为类似工程提供参考。

Jingmi Road(Taiyanggong North Street—Airport South line)project is taken as an example.The guiding principle of"occupying one for another"is adopted for the current traffic volume.Various situations of the main line and key node traffic guiding are expounded in this paper.The traffic guiding is focused on the design methods and ideas,and the difficult problems summarized and analyzed.Various solutions such as optimizing construction space and traffic space and reducing traffic guiding time are put forward to provide reference for similar projects.
