随着汽车保有量和人们出行需求大量增加,交通事故数居高不下,交通安全问题日益突出。引发公路交通事故的主要因素有人、公路环境、车辆、管理等因素,为了克服单一因素评价公路安全状态精度不高的问题,根据层次分析法及专家法,建立公路综合评价指标体系,确定因素集及权重分配,提出安全风险水平评价标准,通过实际项目验证,该方法具有很强的应用价值。
With the increase in the number of car ownership and people traveling, the number of traffic accidents has been on the rise, and the problem of traffic safety has become increasingly prominent. In order to overcome the single factor to evaluate the problem of low precision of road safety status, according to the analytic hierarchy process and the expert law, the highway comprehensive evaluation index system is established, and the factors set are determined And weight distribution, put forward the evaluation standard of safety risk level, which has strong application value through the actual project verification.
