A design concept is developed for a transportable weigh-in-motion sensor with capability to weight individual wheels, axles and the gross weight of passenger-type vehicles moving along a roadway at speeds from 1 to 30 mph. The sensor will sense weight shift associated with vehicle maneuvers and make a correction to each wheel weight. The system installation can be permanent or temporary, and can be an in-ground or surface installation.
