PROPOSED METHOD FOR CALIBRATING WEIGH-IN-MOTION SYSTEMS AND FOR MONITORING THAT CALIBRATION OVER TIME

Calibration of weigh-in-motion (WIM) systems is a difficult process that has many limitations and problems. The problems encountered with using test trucks for calibration are documented. WIM systems often produce differing weights for individual test trucks. Furthermore, calibration achieved in this traditional manner addresses how the system is performing only on those days that tests are conducted. Actual system performance for all other days is unknown. An alternative method for calibrating a system and a method for monitoring the performance of the system on an ongoing basis are proposed. This ongoing monitoring uses an aggregation of specific types of weight data for five-axle tractor-semitrailers that are collected by the system. The results obtained from applying this procedure can also be adapted for use in editing weight data.
