针对目前灾害条件下公路通行能力折算方法研究成果较为缺乏的问题,根据灾害对公路通行能力影响的特点,对灾害的种类进行分类,并设计了公路通行能力折算路段划分方法,在已有研究的基础上,设计了两类灾害条件下公路通行能力折算系数确定方法和通行能力计算方法,利用实际数据进行例证分析表明,所设计方法可以实现灾害条件下公路通行能力折算分析,为灾害条件下应急交通管理提供技术支持。
Aiming at the problem that the research results of highway capacity reduction under current disaster conditions are relatively scarce, the types of disasters are classified according to the impact of disasters on the capacity of highway, and the method of dividing the road capacity into sections is designed. In the existing research Based on the above, two methods to determine the discount coefficient of highway capacity and the capacity calculation method are designed. The analysis of the actual data shows that the design method can realize the conversion analysis of highway capacity under disaster conditions, Traffic management to provide technical support.
