Abstract: A remote object/vehicle identification and speed determination system including a bar code label on each object/vehicle and a device for continuously scanning an area to determine when the object/vehicle is present at a predetermined distance from the scanning device. The scanning device may be responsive to ambient visible or invisible radiation from the label. Each label includes unique identification data for the object/vehicle as well as spaced framing signals used for making distance determinations. Each label may be invisible and may be on or in the windshield of a vehicle.The signals from the scanning device are sampled continuously and the sampled signals are stepped along a shift register. Parallel outputs from the shift register are continuously analyzed so that signals from a single scan across a label are sufficient to determine if an object/vehicle is at a predetermined distance from the scanning device and to read the unique identification data.
