PIEZOELECTRIC-BASED WEIGH-IN-MOTION SYSTEM AND METHOD FOR MOVING VEHICLES

摘要

A piezoelectric vehicle weight-in-motion system having piezoelectric sensors, situated substantially perpendicular to the direction of traffic on a motorway, wherein each of said piezoelectric sensor comprises at least one piezoelectric element configured to produce electrical signal indicative of the force applied on said sensor by a vehicle passing over said sensor; and a processor, receiving signals from said piezoelectric sensors, wherein said processor is capable of determining the speed in which said vehicle passed over said sensors and the load of said vehicle while said vehicle is traveling at normal traffic speed.
