An improved method of weighing trucks while in motion is proposed. To increase efficiency and reduce time lost at weigh stations, the trucking industry needs to exchange data, including weight data, between moving trucks and enforcement facilities. Legally loaded trucks would then be able to proceed without stopping. This involves Weigh-In-Motion. Present weighing techniques involve load cells or similar analog devices, requiring that the tractor and trailer both be equipped and interconnected. The proposed Weigh-In-Motion system is located on the tractor alone. Any trailer or combinations of trailers may be pulled (and weighed) without concern for equipment compatibility or calibration. It offers promise as a more cost-effective way to sense vehicle weight. Up-to-date traceable calibration is assured by repetitively comparing internal weight calculations with data received from the IVHS transponder system.
Anticipated Results:Every over-the-road COMMERCIAL carrier is a potential customer for this technology when the Intelligent Vehicle Highway System is in place. The result is lowered costs to the trucking companies, and a higher level of enforcement of vehicle weight and safety standards.
