Four different measuring devices for use in evaluating highway surface roughness were investigated. The aims of the study were to: (1) examine the field-worthiness of the several systems, (2) develop a feeling for the validity and utility of their respective measurements and (3) determine the effects on their results of such variables as operating speed, driver characteristics, operating temperatures, and other factors.
