| Abstract: | Traffic safety is related to highway alignment,traffic velocity,drivers’ vision response and so on.This article discusses the quantitative relation between highway alignment,traffic velocity and traffic velocity through the rate of change between an angle and length of a central line.Thus the relationship between the vision speed and highway alignment is studied when the traffic velocity is unchanged,and their function relation is given. |

| Keywords: | traffic safety traffic velocity vision velocity vision angular velocity rate of change |
