ABSTRACT:
A weigh-in-motion device and method having at least one transducer pad, each transducer pad having at least one transducer group with transducers positioned essentially perpendicular to the direction of travel. At least one pad microcomputer is provided on each transducer pad having a means for calculating first output signal indicative of weight, second output signal indicative of time, and third output signal indicative of speed. At least one host microcomputer is in electronic communication with each pad microcomputer, and having a means for calculating at least one unknown selected from the group consisting of individual tire weight, individual axle weight, axle spacing, speed profile, longitudinal center of balance, and transverse center of balance.
