为评价公路平面交叉口结构损坏对行车安全性的影响,遵循表征性、综合性、明确性、实用性的原则,对交叉口功能区内路基路面、交通安全设施、照明设施和交通管理设施提出了22项评价指标,运用层次分析法进行两两比较确定指标相对重要性,建立了安全养护评价体系。应用结果表明,该评价方法具有良好的可操作性,对公路平面交叉口的安全保障和养护工作起到指导作用。
In order to evaluate the impact of structural damage of road intersections on driving safety and follow the principles of characterization, comprehensiveness, clarity and practicability, the paper presents the subgrade and pavement, traffic safety facilities, lighting facilities and traffic management facilities within the intersection functional area A total of 22 evaluation indicators, the use of analytic hierarchy process to compare the relative importance of indicators to establish a safety evaluation system. The application results show that the evaluation method has good operability and plays a guiding role in the safety protection and maintenance of the intersection of highway.
