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。针对测量的道路路面数据,阐述由路面数据提取可表征其特性的特征参数,包括基本统计量、国际平整度指数和功率谱密度参数等。在路面特征参数提取基础上,以北京地区真实海量路面测量数据为例,进行道路路面特征参数的统计分析,得到可反映、表征该地区路面特点的统计分析结果。总结道路路面特征参数提取与统计分析方法,展望其应用前景。The forms of data measurement system of road surface and data pre-processing methods of road surface profile in automotive tests were introduced. Based on the measured data of road surface profile, some extracted characteristic parameters of road surface profile were presented, including basic statistics （ mean and standard deviation） , international roughness index （IRI） and parameters of power spectral density （PSD）. After the introduction of extraction methods of characteristic parameters of road profiles, ninny actual measured road surface data in Beijing were taken as examples, their characteristic parameters of road profiles were extracted and these characteristic parameters of road profiles were analyzed statistically. The results showed that these extracting characteristic parameters of road profile methods are simple and effective; these extracted characteristic parameters can be widely used for vehicle tests and highway maintenance and repair. Finally, the extraction and statistical analysis methods of road characteristic parameters were summarized and their application prospects were presented.
