连续长大下坡路段交通事故频发,是公路中典型的事故黑点。治理连续长大下坡交通安全问题,是近几年研究的重点。连续长大下坡路段安全性分析是制定安全处置措施的前提,文章在论述影响连续长大下坡安全问题因素的基础上,探讨了刹车片温度、弯道、刹车失灵车辆速度、路侧防护栏等级及线形协调性分析技术,这些分析技术可作科学、合理制定连续长大下坡路段处置措施的依据。 Continuous growth downhill road traffic accidents, is a typical road accident black spots. It is the focus of research in recent years to deal with the problem of traffic safety in continuous downhill growth. The safety analysis of consecutive long downhill sections is the precondition of making safe disposal measures. Based on the discussion of the factors that affect the safety of continuous downhill, the paper discusses the effects of brake pad temperature, cornering, brake failure vehicle speed, Grade and linear coordination analysis techniques, these analytical techniques can be used as a basis for scientific and rational development of continuous growth downhill sections.
