Abstract
The existed shortage of highway alignment design based on design speed was analyzed.On this condition,two factors of design speed and operating speed were taken into consideration at the same time and according to operating characteristics of car on road and the demand of alignment design,a new design method and design flow were introduced,which can be used as a reference for a design parameter of highway alignment.
