Claim:
1. A system for instantaneous, real-time speed measurement of a select low speed transport vehicle moving in a linear direction of travel and proximate to a bulk material processing station, comprising: a stationary scanning laser and detecting sensor positioned to one side of and generally perpendicular to the direction of travel, said stationary scanning laser and detecting sensor capable of generating a plurality of raw point scan measurement signals over a select arc; a computing device for receiving the plurality of raw point scan measurement signals and applying at least one algorithm to said plurality of raw point scan measurement signals to modulate said plurality of raw point scan measurement signals and provide a first data set representing a flattened two-dimensional linear representation of travel distance of the low speed transport vehicle, saving said first data set in a memory queue, comparing said first data set with a plurality of previously saved datasets in said memory queue using a root mean square deviation algorithm, determining if said first data set exceeds a preselected deviation threshold, accepting said first data set when said preselected deviation threshold is not exceeded, calculating the distance traveled by a transport vehicle from said first data set and computing the speed of said transport vehicle to produce a unique speed profile representative of the transport vehicle.
