I don't know where you got your definition of a speed trap, but most 
states use lines painted on the highway and merely start timing you as you cross
the first, and stop as you cross the second.  The distance between the two being
fixed, the calculation is usually reduced to reading your speed directly from a 
pre-printed chart.  BTW, VASCAR is another of them time-distance calculatin' 
muthas...
