山区高速公路连续长坡路段是高速公路重特大恶性交通事故的多发段,本文介绍的高速公路连续长下坡行车安全措施包含设置反坡路段、避险车道、强制休息区(服务区、停车区),完善交通安全设施等,大多数措施都已经应用在典型长下坡路段的工程实践中,并取得较为显著的效果。公路建设相关部门在项目实施过程中可以借鉴运用这些措施,减少交通事故,提高连续长下坡路段的行车安全性。 The continuous long-slope section of mountainous expressway is a multiple section of serious and serious accident on expressway. The safety measures for continuous long-downhill expressway construction introduced in this paper include setting of reverse slope section, safe-haven lane and mandatory rest area (service area, parking area ), Improving traffic safety facilities, most of the measures have been applied in the engineering practice of typical long downhill sections and have achieved remarkable results. Relevant departments of highway construction may draw lessons from these measures to reduce traffic accidents and improve the driving safety of the continuous long downhill sections during the project implementation.
