摘　　要：为了研究山区农村公路路侧安全影响因素、安全评价方法及安全保障措施,对陕西咸阳地区农村公路进行了实地调查,并结合专家意见,应用层次分析法和灰色理论进行了相关分析。结果表明:影响山区农村公路路侧安全的因素有交通量、交通组成、路侧特征及线形特征;适用于山区农村公路路侧安全评价的10个指标为平曲线变量、竖曲线变量、白天平均小时交通量、摩托车比重、路侧事故数、路侧伤亡事故数、路侧净区满足率、路侧深度、离散危险物密度及横向距离;山区农村公路路侧危险度宜划分为3个等级:Ⅰ级、Ⅱ级、Ⅲ级,且不同危险度等级应采用不同的安全防护对策。There are many influence factors on the roadside safety of mountainous rural highway, but no specific safety evaluation and safety measures. To resolve these problems, an on-site roadside safety investigation was done in Xianyang area. The investigating datum were analyzed with experts＇ markings, analytic hierarchy process and grey theory evaluation method. Results show that： the influence factors on roadside safety are traffic volume and compositions, roadside features and road alignment. The evaluation indicators of roadside safety were put forward which contain horizontal curve variable, vertical curve variable, AHT（average hourly traffic）during daytime, motor proportion, numbers of roadside accident, casualties of roadside accident, fill rate of roadside recover distance, depth of roadside, closeness and lateral separation of discrete obstacles. The roadside hazard should be classified into three levels which are classⅠ, Ⅱand Ⅲ, and different safeguard measures should be defined to suit for different hazards. 5 tabs, 8 figs, 10 refs.
