A system tracks vehicles within a terminal and includes at least one tag
interrogator mounted on a vehicle to be identified and tracked within the
terminal. The tag interrogator is operative for emitting a signal
containing data identifying the vehicle to which the tag interrogator is
mounted. At least one tag transmitter is fixed at a known location within
the terminal where vehicles are to be identified and receptive to a tag
interrogator on the vehicle when the vehicle passes within proximity to
the fixed tag transmitter for transmitting a wireless RF signal having
data identifying the tag transmitter and identifying the tag interrogator
as an identifier for the vehicle to which the tag interrogator is
mounted. At least one access point is positioned at the terminal for
receiving the RF signal from the tag transmitter for subsequent
processing to verify vehicle identity at the known location.
