摘　　要：根据汽车在公路上行驶的特性和公路线形设计的要求,研究了以设计速度作为依据的公路线形设计方法,发现各技术指标取值不合理、相互组合不协调,易发生交通事故等问题。提出可能速度的概念及在公路线形设计的应用方法,可以有效地检查和评价公路线形设计成果,作为公路几何设计技术指标取值的依据。According to operating characteristics of car on road and the demand of alignment design, the method of highway alignment design based on design velocity were researched. Some questions such as the unreasonable application of design parameter, inconsistent combination of alignment and easily resulting in traffic accident were found. The concept of possible velocity and its application in design for highway alignment were put forward. It can be used effectively in checking and evaluating estimation highway alignment, and can provide scientific basis for design parameter of highway alignment.
