The report describes the objectives, scope and findings of the pilot study of a high speed, portable Weigh-In-Motion System. The main components of the portable WIM equipment consists of a Weighpad, a Weighman, a Retriever and a set of traffic loops. The system was installed in the vicinity of truck weigh stations along interstate highways. Field calibration of the system was accomplished at these weigh stations with the cooperation of the Weighmasters. Static weights vs. WIM weights for total and various axle weights were compared. The percent of overweight vehicles for open versus closed weigh stations was compared to evaluate the effectiveness of the permanent WIM sites. The WIM system was found to be accurate to within 20% of static gross weight, 90% of the time. Individual axle weight accuracy ranged from 30% for drive and trailer axles to 40% of steering axles, 90% of the time.
