I just realized how tribvial it is for the state to gather traffic speed.  THey just put EZPASS detectors on underpasses and then keep track of how long it take any given ID to go from one detector to the next.

Is this how they do it?  I had heard they used cell phones, ut I think the EZ pass woiuld be more straight forward...
