Abstract

An apparatus and method for measuring the speed and/or acceleration of a vehicle traveling on a vehicle path includes at least one radiation emitting device (12) and at least two radiation receiving devices (12). Mirrors (14) and/or beam splitters are used to direct at least one beam across the vehicle path. A controller (22) calculates speed and/or acceleration of the vehicle in response to interruption of the at least one beam by a passing vehicle. The system can also include a mass sensor that detects the mass of the vehicle.
