Accuracy of traffic monitoring equipment field tests

The tests being performed by the Georgia Tech Research Institute and the Georgia Department of Transportation are described. The object of these tests is to determine the adequacy of vehicle counting devices, the adequacy of equipment to correctly sort vehicles into the 13 FWHA vehicle classes, the adequacy of automatic measurement of overall vehicle length, the effects of vehicle and axle sensor technology on the accuracy of the vehicle classification, and the effects of vehicle repetitions and weather on pneumatic tube (and other) axle sensors.
