摘要
该文分析了停车视距计算参数的取值,并计算了高速公路圆曲线外侧超车道在不同设计速度下能够提供的横净距。通过示例分别计算了三种不同参数取值下的停车视距和横净距。
The article analyzes the calculating parameters of stopping sight distance,calculates the clear transverse distance of overtaking lane at outside of circular curve in expressway by the different design speeds,and separately calculates the stopping sights and clear transverse distances by three different parameters through the practical cases.
