Abstract
Measuring system.
It comprises a pair of sensing stations, spaced apart a known distance along a path of travel of the vehicle, each detection station comprising a series of electromagnetic radiation emitters extending vertically, disposed on a side of the path and at least one sensor disposed on the other side.
The beams from the emitters are directed at the detector so that each of the parts of the vehicle which is located between the emitters and the detector intercepts some of the beams to produce a variation in characteristic of the electromagnetic radiation incident on the detector which has the function of identifying this part of the vehicle.
Data processing means act to the outputs of the detectors to the two stations to provide a measure of the vehicle in relation to the speed.
