Abstract: Based on the freeways in many mountainous areas of China, the accidents of continuous downhill sections are high. The prevention and control technology proposed in this way can reduce the accident rate and ensure the safety of life and property of drivers and passengers. This paper first reviews the research status of the prevention and control technology for continuous long downhill sections, and then describes the current prevention and control techniques for this section. Finally, it puts forward the future research focus of this section and looks forward to the future development trend.
Keywords: Continuous long down-slope; Road traffic; The prevention and control technology for traffic accidents

前言
我国地势起伏较大,长下坡路段在国内高速公路的设计中是不可避免的,尤其在我国西部山区发生在长下坡路段的重大、恶性交通事故数量较多。根据公安部和国家安全生产监督管理局统计分析确定了全国29处危险路段,其中长大下坡路段有16处,占公路危险路段总数的55.52%。上述路段大多地处山区多雨多雾、高海拔的道路和不良气候条件中,由能见度不高、制动器热衰退、路面附着系数低等不利因素引发的交通事故,造成了巨大的经济损失和人员伤亡,社会各界开始对连续长下坡路段的交通安全引起高度重视[1]。

1.1 国外研究现状
随着全球高速公路和物流运输行业的快速发展,高速公路的交通流量和交通组成也发生了巨大的变化,重型载货汽车在所有高速公路通行车型中所占的比例也越来越高,由于重型载货汽车在长大下坡路段连续制动引起的制动热衰退现象,导致刹车失灵的交通事故比例增加,也凸显了此路型存在的安全隐患。……
