高速公路的迅速发展给我们的生活和出行带来了极大的便利。当高速公路建设逐步向山区延伸时,经常会出现连续长下坡路段(受山区地理环境影响),容易使车辆特别是重载汽车失控,从而引发事故。为此,在高速公路连续长下坡路段右侧的适当位置,会设置紧急避险车道,以使失控车辆能够驶离主车道,安全减速直至停止,避免事故的发生。 The rapid development of the expressway has brought great convenience to our life and travel. When the expressway construction gradually extends to the mountainous areas, continuous long downhill sections (affected by the geography of the mountainous area) often occur, and vehicles, especially heavy vehicles, are easily out of control, thus causing accidents. To this end, an emergency haven lane will be provided in the right of the continuous downhill section of the expressway to allow the out of control vehicle to leave the main lane and decelerate safely until it stops to avoid the accident.
