摘要

介绍了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，提取了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，提出了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，进行了典型路面的提取与合成，得到了可反映和表征该地区路面特点的典型路面。最后总结了典型路面的提取与合成方法，展望了其应用前景。

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, using the Radar Chart as the analytical tool, there is a new extraction and synthesis algorithm of typical road sections which was proposed. As an example, the actual measurement road surface data in Beijing was calculated and compiled statistics. Their characteristic parameters of road profiles were extracted and the typical road sections were synthesized. The extraction and synthesis results show that the typical road sections have obvious effect and can represent characteristics of the region. Finally, the extraction and synthesis method of typical road sections is summarized and the prospect of its application is presented.
