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。

Abstract

It’s reviewed that the components of measurement system of road surface data and pre-processing methods of road surface profile in automotive test. Based on the measurement data of road surface profile, there are some characteristic parameters of road surface profile which are extracted, including the basic statistics (Mean and Standard Deviation), International Roughness Index (IRI) and the parameters of Power Spectrum Density (PSD). After the introduction of extraction methods of characteristic parameters of road profiles, many actual measurement road surface data in Beijing as examples, their characteristic parameters of road profiles were extracted and these characteristic parameters of road profiles were compiled statistics. The extraction and statistics results show that these extraction characteristic parameters methods of road profile are simple and has obvious effect. These extraction characteristic parameters can be widely applied to vehicle tests and highway maintenance and repair. Finally, extraction and statistics methods of road characteristic parameters are summarized and the prospects of their application are presented.
