Abstract
A Weigh-in-Motion (WIM) system is defined as a device that measures the dynamic axle weight of a moving vehicle to estimate the corresponding static axle mass. This report documents the status of WIM technology, focusing on Australia's situation. Recommendations on delivering Australia the best opportunities in overall WIM technology are also included. Topics covered in the report include WIM concepts, history of WIM technology, calibration and evaluation, data output and reporting, applications of WIM technology, current research, and future developments.
