城市道路加减速车道长度取值的研究与探讨

结合城市高架快速道路匝道出入口勘察设计实践,本文针对城市道路平行式加减速车道长度的设计进行研究与探讨,提出科学合理的设计方案与长度取值,选用合理的设计规范。

Combining with the practice of surveying and designing entrances and exits of urban elevated expressway ramps, this paper studies and discusses the design of parallel acceleration and deceleration lane lengths for urban roads, proposes scientific and rational design schemes and length values, and selects reasonable design specifications.
