基于检评管理的城市道路平整度影响因素分析

Analysis of Influencing Factors of Urban Road Roughness Based on Detection and Evaluation Management

城市道路平整度直接反映路面行驶质量及行驶舒适性,是城市道路管理的重要指标。结合城市道路平整度检测的实际情况,从平整度等级评定标准、道路特征等角度分析了城市道路平整度的影响因素。结果表明:司乘人员的主观行驶感受往往与参照评定标准得出的评价结果存在差异,可见主观上不能准确区分路面实际的平整度状况;城市道路交叉口、道路井盖以及路面连续病害修补均会在不同程度上影响城市道路平整度;平整度评价单元的划分方式同样会影响评价结果,因此应以道路特征按平均长度或面积进行标准单元划分。

The roughness of urban road directly reflects the driving quality and driving comfort,and is an important index of urban road management. Combined with the testing practice of urban road roughness,the influencing factors of urban road roughness are analyzed from different angles such as evaluation standards and road characteristics. The results show that the subjective driving experience of drivers or pedestrians is often different from the evaluation results of evaluation standards,and the actual roughness of pavement can not be accurately distinguished subjectively;intersection,road manhole cover and continuous repair of pavement diseases all affect the roughness of urban roads to varying degrees;the division method of roughness evaluation unit also has an impact,and the standard unit should be divided by the average length or area considering the road characteristics.
