A STUDY OF THE RELATIONSHIPS BETWEEN VARIOUS CLASSES OF ROAD-SURFACE ROUGHNESS AND HUMAN RATINGS OF RIDING QUALITY

In this study, statistical relationships between each of several classes of road roughness and human panel ratings of riding quality are developed. For this purpose, the roughness is categorized through digital filtering methods on the basis of wavelength. Longitudinal and transverse surface effects are also studied. Multiple regression analysis is used to relate the panel ratings to roughness as a whole and to the individual types of roughness. By using the models so developed, one can obtain for any given road section a measure of riding quality corresponding to each of a set of important aspects of roughness. Use of the models is demonstrated by analyzing the roughness of an illustrative road section just before, just after, and a year after an overlay.
