山区高速公路连续长下坡安全评价及措施研究

Safety Evaluation and Measures Research for Continuous Long Downgrades of Expressways in Mountainous Area

山区高速公路地形条件复杂,地势高差大,连续长下坡众多,特别对大型货车的行车安全造成较大的安全隐患。论文从交通安全设施设置、刹车鼓温度预测、避险车道等方面对运营山区高速公路连续长下坡路段进行安全性评价,提出一系列改善措施建议,以期减少事故的发生概率,提高连续长下坡路段的行车安全。

Highway in mountainous areas has complex topographic conditions, great elevation difference and numerous continuous long downgrades, which will bring great potential safety hazards for the driving of trucks. This paper evaluates the safety of the long downhill section of mountain expressway from the aspects of traffic safety facilities setting, brake drum temperature prediction and safe-haven lane, and puts forward a series of improvement measures to reduce the probability of accidents and improve the driving safety of the long downhill section.
