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.

The objective of this paper is to demonstrate the use of computer modeling and simulation as an effective analytical tool which can be integrated with representative data from user duty cycles to validate test data recorded from a vehicle. Computer modeling is an increasingly important design tool, but the necessity of real-world test data is often overlooked. This paper will present an example of the Logistics Vehicle System Replacment (LVSR), using real-world proving ground data as inputs to the vehicle model, as well as instrumented vehicle test data to validate outputs of the vehicle model.
