| 摘 要： | 纵断面设计是公路路线设计的重点,是公路安全设计的核心。纵坡坡度和坡长是公路纵断面线形设计的两项重要控制参数,与交通安全有着密切的关系。在纵坡安全影响分析的基础上,通过研究纵坡坡度、坡长及竖曲线与安全性的关系,从纵断面线形设计角度提出改善公路交通安全的具体措施,可为交通安全设计提供技术支持,预防和减少交通事故。

| Abstract: | Vertical alignment design is the emphasis of highway alignment design. It is also the core of road safety design. Longitudinal slope and grade length are two controlling parameters of vertical alignment design, which are closely related to traffic safety. Based on the safety impact analysis of longitudinal slope, the relationships of the longitudinal grade, length of grade and vertical curves with traffic security are studied. Specific measures to improve highway transportation safety design from vertical a... |
