| Abstract: | 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. |
