Abstract
A roadway information system is disclosed with components generating and using vehicle signatures for vehicles passing near sensor pods located on or near lanes in a multiple input-output roadway node. Means and/or processors for matching incoming and outgoing vehicle signatures are disclosed creating an in-out vehicle match table used to generate a vehicle movement estimate or its components including a travel time and/or vehicle count that may be created and/or used in response to a match tally exceeding a threshold or the stimulation of a timing signal.
