The Weigh In Motion (WIM) Data Logger in combination with the Lineas WIM sensors allows to monitor traffic and to gather accurate vehicle data under rolling traffic conditions in real time. WIM systems with the WIM Data Logger measure gross vehicle weight, axle load and wheel load amongst others for preselection of overloaded vehicles, direct weight enforcement, toll by weight or traffic data collection. In addition, it even detects flat tires and therefore helps to increase safety on the the road.
