高等级公路沿线设施养护质量评价方法研究

在充分借鉴现有规范的基础上,重新确立了评价对象的组成,建立了高等级公路沿线设施养护状况指数(TCI)的计算模型结构,并且利用层次分析法的优化算法计算得到了模型结构中各评价对象的相对权重值。定义了评价对象的缺损,并且制定了确定沿线设施单处缺损扣分值的工作流程,给出了各评价对象的单处缺损扣分值。将研究成果应用于江苏省高等级公路沿线设施的养护质量评价中,结果表明,利用本评价方法得到沿线设施综合评分值与专家主观评分值线性回归判定系数R2达到0.95以上;与现有规范得分相比,分值分布较均匀。

Research on Method of Traffic-facility Maintenance Quality Evaluation for High-level Roads

The evaluating objects were re-determined and a modeling structure for calculating Traffic-facility Condition Index(TCI) for high-level roads was constructed based on the existing standards.Furthermore,the weights for each evaluating object in the modeling structure were calculated using one of optimum Analytic Hierarchy Process.The evaluation measures for damaged objects were defined and the process of determining the deduction value for each damage were worked out.Based on the applications in Jiangsu Province,the result shows that(1)the coefficients of linear regression determination(R2 value) are larger than 0.95,which shows strong correlation between the overall evaluation scores calculated by the models and the subjective evaluation scores from the experts;(2)the evaluation scores distributes more evenly compared with the ones calculated using the existing standard.
