First Claim
Patent Images
1. Apparatus, comprising at least one instance of a member of a generating group consisting of:
- a means for generating (100) at least one vehicle movement estimate (80) from at least one vehicle signature (26) each based upon sensor readings (22) from at least two sensor pods (20) situated near both incoming lanes (8) of incoming vehicles (6) and outgoing lanes (8) of outgoing vehicles (6),with both said incoming lanes and said outgoing lanes included in a roadway node (4) with the sum of said incoming lanes and said outgoing lanes is at least three,with said vehicle movement estimate including a travel time and a vehicle count,with said vehicle movement estimate meeting a quality criteria; and
a processor configured to generate said vehicle movement estimate in response to a match tally exceeding a match tally threshold.

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.
