摘　　要：停车视距是影响高速公路行车安全和建设规模的重要设计指标,中国《公路路线设计规范》(JTG D20-2017)、美国公路设计规范、法国公路设计规范均对高速公路不同设计速度下的停车视距进行了规定,并给出了相关计算方法。对中、美、法三国规范对停车视距的规定进行对比分析研究,指出了停车视距传统物理运动模型、理论计算公式及相关参数选取方面的不足,并对其进行了修正,供相关人员参考。The stopping sight distance is an important design index that influences the driving safety and construction scale of expressway.The stopping sight distances under different design speeds of expressway are stipulated by Design Specification for Highway Alignment in China(JTG D20-2017),Highway Design Specification in the United Sates and Highway Design Specification in France,and relevant calculation methods are given.The research on the contrastive analysis of stipulation of specifications in three countries like China,the United States and France on the stopping sight distances is made,the deficiencies in aspects like traditional physical motion model,theoretical calculation formula and relevant parameter selection of stopping sight distance are pointed out,and the correction is made,so as to provide reference for relevant personnel.
