Abstract

Problem Solved By This Invention: Safety on public roads is a growing concern. This invention adds Radio Frequency Identification (RFID) tags to automobiles for traffic control. RFID readers can be added to the highway system infrastructure to read the RFID tags and use it for traffic control including, speeding, going through a red light, tracking tolls on a bridge, traffic count, etc.

RFID for Traffic Control

   Problem Solved By This Invention:

   Safety on public roads is a growing concern.  This
invention adds Radio Frequency Identification (RFID) tags to
automobiles for traffic control.  RFID readers can be added to the
highway system infrastructure to read the RFID tags and use it for
traffic control including, speeding, going through a red light,
tracking tolls on a bridge, traffic count, etc.

   Description of Invention:

   The RFID tag contains the automobile Vehicle Identification
number (VIN).  The VIN is an industry standard and each automobile
has an unique VIN.  The VIN is tagged to an individual by the
registration of your automobile.  Therefore we know who owns the
automobile once we have the VIN number.  The VIN number would be
programmed in the automobile when it is built.  This would be done
at the same time the VIN added to other parts of the automobile.

   RFID readers can then be installed at red lights and other
traffic control points.  The RFID readers can then identify the cars
that pass by.  This information can then be sent via the network to a
central processing location.  The central processing location can
contain computers which would use the raw information passed to it to
determine what action to take.

   Following are examples on how this can be used for traffic
control:
  o  Traffic flow:  RFID readers can count number of cars passing
     in each direction in a four way intersection.  Red/gr...
