FHWA DEMONSTRATION PROJECT #966. AUTOMATED TRAFFIC/TRUCK WEIGHT MONITORING EQUIPMENT (WEIGH-IN-MOTION (W.I.M.)). EXECUTIVE SUMMARY

Six WIM systems were obtained and operated for periods of up to a year. The systems available were the CMI-IRD load cell system, the PAT bending plate system, the Streeter-Richardson bending plate system and Capacitance Pad system, the Golden River Capacitance Pad system and the Bridge Weigh Systems, Inc. unit. All systems operated with a minimum of maintenance problems and supplied data within the range of approximately plus or minus 10-15% on gross weights when installed on typical pavements. Costs of systems range from about $25,000 to $100,000. The two most important future needs are systems in the $5,000 class and a foolproof method of calibration of the scale systems.
