| 摘 要： | 长大下坡路段往往是事故多发路段。本文基于实测数据,分析长下坡路段道路线形设计的交通安全影响因素,总结出下坡路段道路加速度模型,根据加速度变化量与交通安全之间的关系,提出以加速度的变化量为评价道路安全的量化指标,确定下坡路段道路线形设计的评价标准,来评价其安全性和合理性。

| Abstract: | Long and steep downhill roads are usually the hazardous location. Based on the data from on -the -spot survey, the paper analyzes safety factors of the road linear design for the long downhill section, and summarizes the road acceleration model of downhill section. According to the relationship between the change of acceleration and traffic safety, proposes the change of acceleration to be the quantitative indicators for the road safety evaluation, and determines the evaluation criteria of the road linear d... |
