摘要
汽车在曲线上行驶时,横向加速度的变化是平、纵、横三方面综合作用的结果。建立了横向加速度变化率与三者之间的关系,可作为路线各几何元素和舒适性的评价指标。据此对传统公路路线几何元素进行了讨论。
When vehicles are moving on the highway, the lateral change of acceleration is the result of being acted on by the horizontal,verical and lateral aspects. In this paper, the relationships between the lateral change of acceleration and the three aspects are set up, and the lateral change of acceleration can act as a criterion to evaluate the geometric factors of highway and the characteristic of comfort. In addition, this paper discusses the geometric factors of the classical highway alignment.
