Abstract
【Abstract】 The authors examined an application of parametric curves used as spatial curves to highway alignment. Both of centrifugal acceleration and its rate of increase while driving the highway alignment designed by several kinds of parametric curve were compared. As a result of the examination, it was shown that cubic B-spline curves are applicable to the case of highgrade of alignment design and quadratic B-spline curves are applicable to the case of low-grade of alignment design.
