Weigh-in-motion (WIM) is the process of measuring the dynamic forces of moving vehicle tires on pavements and estimating the corresponding tire loads of the static vehicle. The dynamic forces of moving vehicles include the effects of road surface roughness and are modified by vehicle characteristics such as sprung and unsprung mass, tire inflation pressures, out-of-round or dynamically unbalanced wheels and tires, vehicle cargo, suspension damping, and the vehicles’ aerodynamic characteristics ...
