1. A system for weighing moving vehicles, comprising:

  • a weight transducer positioned in the path of a moving vehicle providing a load signal indicative of the vehicle loading as the vehicle travels across the transducer;

    a vehicle speed sensor providing second a output signal indicative of the vehicle speed as the vehicle travels across the transducer; and

    a processor operable for calculating the weight of the moving vehicle by integrating substantially all of the first output signal over time as the vehicle travels over the transducer and multiplying the integration result by the vehicle speed and a calibration constant.
