Vertical accelerations of a passenger in an automobile are automatically summed while traveling a section of road at 51.5 mph. A roughness index is obtained by summing the acclerations and dividing by the time elapsed during the test. The index is subjectively related to the riding quality of pavements. Continuity in measurements since 1957 has been preserved through correlations among successive vehicles involved and reference pavements. (Author)
