摘要: 利用五次Bézier 曲线,构造了一条含形状参数的两平行线间满足G2 连续的缓和曲
线。这条曲线在t=1/2 含有唯一的曲率极值点。利用形状参数可以方便地控制曲率极值的大小和
调节曲线的形状。

Abstract: By using quintic Bézier curve, the transition curve which is G2 continuous with a shape
parameter is constructed between two parallel lines. This curve at t=1/2 contains a unique curvature
extreme. It can be easily controlled curvature extremes and adjust the shape of the curve by using the
shape parameter.

Key words: transition curve, quintic Bézier curve, parallel lines, monotone curvature
