通过对山区一般公路路侧地形状况与车辆冲出路外事故伤亡情况关系的研究,提出了路侧危险度的概念,并给出了路侧危险度等级划分的量化计算办法。路侧危险度等级的合理划分为准确确定路侧危险状况,合理设置不同等级的安全护栏提供了依据,进而有效提高山区一般公路的安全水平。
Through the research on the relationship between the terrain condition on the side of mountainous general road and the casualty situation of vehicle rushing out of the road, the concept of roadside risk is put forward and the quantitative calculation method of roadside risk level classification is given. The reasonable classification of the roadside risk level provides the basis for accurately determining the roadside dangerous situation and setting the safety fence of different levels reasonably, so as to effectively improve the safety level of the general highway in the mountainous area.
