贵州山区高速公路典型安全问题对策研究

Study on typical mountainous highway safety problems and countermeasures in Guizhou province

贵州地貌受地质构造影响,地形落差较大,连续长大纵坡、特长隧道、隧道群等不良行车环境和大雾、凝冻等恶劣天气环境较多,不利于行车安全。总结了贵州省山区高速公路的典型安全特点,并提出针对性改善意见,为贵州山区高速公路安全研究提供理论依据。

Owing to the geological structure influence of geomorphology of Guizhou province,safety driving is limited by various factors,such as big geomorphology difference,continuous large longitudinal slope,super-long tunnel and tunnel group and other poor driving environment and heavy frog and frozen weather and other poor weather conditions.The paper summarizes typical mountainous highway safety properties of Guizhou province,and puts forward corresponding improving suggestions,which has provided theoretical basis for study mountainous highway driving safety of Guizhou province.
