双车道公路线形连续性及舒适性评价研究

针对公路线形连续是保证汽车安全行驶的基本要求,提出相邻路段运行车速相协调的路线设计理念,并提出双车道公路线形连续性评价标准,旨在为设计和改建双车道公路提供重要依据,提高线形设计质量,减少交通事故。经实例分析证实所提标准较为合理,并根据分析结果,讨论并提出了相应的改善措施。此外,从驾驶员的角度对线形的舒适性做出了评价,并提出双车道公路线形舒适性的评价标准,更加体现了"以人为本的交通理念"。

Analysis and Evaluation of Two-lane Highway Alignment Consistency and Comfortableness

Operating speed difference is carried on to evaluate highway alignment consistency,as well as the standard to evaluate two-lane highway alignment consistency which offers important gist for two-lane highway design and rebuilding.The standard then is proved to be logical,and is of important application value.Furthermore,the comfortableness of alignment is evaluated,and the standard to evaluate two-lane highway alignment comfortableness is brought out.
