Research Abstract	Axle weighing system measures axle weights of in-motion vehicles. A method have been studied for estimating the axle weights by processing weight signals from the axle weighing system to improve the accuracy of the measured axle weights. In this study, to examine and improve the accuracy of the measured axle weights, a miniature instrumented vehicle and a miniature axle weighing system have been developed. Also each function of the miniature models is verified through the experiments to obtain motion data of the miniature instrumented vehicle and weight signals. By using the obtained weight signals, it has been examined that the method can estimate the vibration component in the weight signals adequately.
