山区高速公路长大下坡交通安全特征分析及对策

The analysis and countermeasure of mountain highway long and steep downgrade traffic safety characteristic

我国山区高速公路所处的地形复杂,地貌特殊,因此其具有弯道多、转角大的特点,在汽车行驶的过程中可能会遇到较大的高差起伏,且山区高速公路的纵坡相对陡、长,所以其相对平原地区的高速公路危险性较大,易发生交通事故,其交通安全性较差,将简要分析山区高速公路长大下坡交通安全特征分析及对策。

Our mountain highway which complex terrain,special topography,thus having more curves,big corners,and great up and downs when driving,and the longitudinal slope of mountain is relatively steep and long,so highway on relatively large plains is dangerous,and traffic accidents are easily happened with poor traffic safety. This article will briefly analyze long and steep downgrade of mountain highway traffic safety characteristic analysis and countermeasures.
