摘要
由于山区道路急弯陡坡路段事故频频发生,且呈逐年上升趋势,因此通过对山区道路交通事故路段分布特征的分析,综合选取安全度模型参数,从道路线形、车辆设计参数、车路相关参数三方面建立安全度评价指标体系,结合模糊数学法建立了山区道路安全度模型。最后通过实例分析,验证了安全度模型的评价符合山区道路的安全状态。
Due to the sharp curve steep,the accidents occur frequently in mountain roads,and there is a trend of increase.Therefore,this paper analyzes the distribution characteristics of road traffic accidents,selects parameters of the safety degree model,establishes a safety evaluation index system from three aspects including road alignment,vehicle design parameters,related parameters of the road and vehicle,and establishes a mountain road safety model based on fuzzy mathematics method.Finally,a case study validates that the evaluation of the safety degree model fits with the safety state of the mountain road.
