The objective of this study has been to develop relationships between pavement roughness and weigh-in-motion (WIM) system measurement error for individual axles, tandem axles, gross weight and axle spacing. The dynamic weight measured by a WIM scale is determined by the dynamic response of the vehicle system to the pavement roughness. A dynamic sim
