摘 要:介绍道路路面数据测量系统的构成和数据预处理方法。针对道路路面测量数据,提取可表征路面特点的特征参数,包括基本统计量、国际平整度指数和功率谱密度参数等。在此基础上,使用雷达图统计分析工具,提出典型路段的提取与合成算法。并以北京地区真实的海量路面测量数据为例,进行典型路面的提取与合成,得到可反映和表征该地区路面特点的典型路面。总结典型路面的提取与合成方法,展望其应用前景。The construct of measurement system of road surface data and pre-processing methods were reviewed. Based on the measurement data of road surface profiles, characteristic parameters of road surface profiles were extracted, including basic statistics (mean and standard deviation), international roughness index (IRI) and parameters of power spectral density (PSD). After introducing extraction methods of characteristic parameters of road profiles, using radar charts as an analysis tool, a new extraction and synthesis method of typical road surfaces was proposed. As an example, the actual measured road surface data in Beijing were calculated and processed statistically. The characteristic parameters of road profiles were extracted and typical road surfaces were synthesized. The extraction and synthesis results showed that the typical road surfaces have obvious features and can represent the characteristics of the region roads. Finally, the extraction and synthesis method of typical road surfaces was summarized and the prospects of its application were presented.
