摘　　要：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"。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.
