WebSurface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is ... Webroad surface roughness on ride comfort conducted in the 1980s (9). The objective of that work was to determine how road profiles were linked to the subjective opinion about the road ride quality from members of the public. Thus, RN is linked by statistical correlation to public opinion of ride quality (10).

WebThe International Roughness Index (IRI) is the most commonly used measure of road roughness and is computed from a road’s longitudinal profile using a mathematical … In the early 1980s the highway engineering community identified road roughness as the primary indicator of the utility of a highway network to road users. However, existing methods used to characterize roughness were not reproducible by different agencies using different measuring equipment and methods. Even within a given agency, the methods were not necessarily repeatable. Nor were they stable with time.
