    A method for measuring the longitudinal profile of a highway or off-highway surface is given. As a paper presented at a “Vehicle, Tire Pavement Interface” meeting, this profile method is of particular interest to those involved in the study of vehicle response, as well as pavement roughness. The advantages and uses of a wave-number spectrum presentation of road roughness is discussed.
