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 accelerations 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. The rate of deterioration in ride quality was found to be different for each pavement type and varied according to the original or as-constructed roughness of the pavement, structural number, and the type of highway facility involved.
