摘要
卵形曲线是路线设计中几种复杂的曲线之一,但与其相关内容的介绍很少,因此根据卵形曲线的定义及设计参数给出其坐标的计算过程很有实际意义。
The egg-shaped curves is one of the complex curves for design road line, but the related contend is very rare. So, there are much practical meanings for giving the course of computation coordinates of egg-shaped curves according to the definition of egg-shaped curves and its design-parameter.
