摘要: 山区长大下坡路段往往是事故多发路段,尤其是重型载重车辆的超载快速行驶更易引发重大、恶性交通事故. 根据下坡路段事故统计资料,分析纵坡坡度、坡长、竖曲线和下坡衔接平曲线与道路安全的关系,为提高长大下坡路 段安全,优化纵面设计提供参考.

关键词: 纵坡, 坡长限制, 竖曲线, 运行速度

Abstract: long and steep downhill mountain roads are usually the hazardous locations,especially for the overload and fast going heavy-duty vehicles which are more likely to occur to the trafic accidents.So the relationship between longitudinal gradi- ent,grade length limit,vertical cLlrve an d safety is analyzed,which can be referred to improve the safety and optimize the profile design.

Key words: longitudinal gradient, grade length limit, vertical curve, operating speed
