Data Collection on I-90 in Washington State, USA
Information from the WIM site was also shared with enforcement officials and used to identify vehicles with potential weight violations.
Upon calibration at installation, GVW error was less than 3%, and single axle data less than 4% (95% confidence level). Commercial vehicle safety officials have also stopped vehicles to measure static axle weights for enforcement based off the WIM site data. They found single axle weights having less than 5% error during in-service comparisons of the WIM site to static weights.
