The Virginia Center for Innovation and Transportation Research and Virginia Tech installed a structural health monitoring (SHM) system on a Virginia bridge. Using data from this SHM system as input, a procedure was developed to provide information on the lane occupancy, speed, classification and gross vehicle weight of heavy trucks. The resulting information is very useful for bridge management. The data also augments existing bridge WIM data collection sites in Virginia. The procedure could add functionality to other bridge SHM systems in Virginia. The system provides useful information on truck loading at low cost.
