As part of a research programme being carried out in the Laboratory to quantify the relationships between road unevenness and riding comfort, the level of loading applied to the road structure, and vehicle handling and control, the relationship between subjective assessment of ride and an objective measure of ride has been investigated. The objective measure of ride is defined to be the root-mean-square of the vertical acceeleration at the person-seat interface in a moving vehicle. This Report describes an experiment designed to examine the repeatability of the objective measure of ride and the variability of its subjective assessments.
