摘要
以4车道高速公路各设计时速的标准横断面为前提,分析了满足停车视距的临界圆曲线半径;论述了几种小半径圆曲线满足停车视距的处理措施及其使用的圆曲线半径的范围;计算了不同小半径的合理限制车速。
Setting standard cross - section of 4 - lane expressway design speed as precondition, critical circular curve radius of stopping sight distance is analyzed ; several treatment measures that radius circular curves satisfy stopping sight distance and the range of circular curve radius are discussed; reasonable speed limits of different minor radius are calculated.
