摘要
针对现行的以设计速度为依据的公路线形设计存在的局限性,在二级公路设计中,运用运行速度的理念对公路线形进行分析评价,发现存在的问题,优化平纵线形,改善行驶条件,提高道路交通安全。
In view of limitations existing in highway alignment design based on design speed,the idea of running speed was used for analysis and evaluation of highway alignment in the grade 2 highway design,the existing problems were found,the horizontal and longitudinal alignment were optimized,the driving condition was improved,and the road traffic safety was increased.
