In 1987 a test was conducted of a high precision, low speed Weigh-in-Motion (WIM) system that could accurately weigh vehicle axles and be used for enforcement purposes at weight scale facilities. A complete prototype system was installed for testing and demonstration at Clavet, Saskatchewan. The system was checked against weights obtained from the static scale in use at the site over nine months. Two additional systems were installed in British Columbia and were monitored over five months, during which the system was subjected to a variety of hostile conditions. This report describes the technical development of the in-road hardware and the data acquisition electronics; the operational characteristics; prototype testing; and the B.C. sites and monitoring.
