Abstract:The objective of the Unaccompanied Baggage Detection System (UBDS) Project has
been to gain field experience with a system designed to identify passengers who
check baggage for a flight and subsequently fail to board that flight. In the first
phase of the project, various identification techniques including bar-code, magnetic
stripe, optical character readers, and micro-wave transponders, were reviewed.
Bar-code was selected because of its low cost and because of the off-the-shelf
availability of all of the necessary components for a system.
During a March, 1986 meeting of airline security officials, the representative of
United Airlines volunteered his carrier to host a UBDS demonstration. UAL's station
at Green Airport near Providence, R.I. was selected because of its proximity to TSC
and its scale of operations which allows collection of a substantial volume of data
while incurring costs for only a single gate.
Although it was recognized at the start that integration of the UBDS with UAL's
Apollo reservations system would provide the most realistic operating environment,
the lead-time for such integration was estimated at more than one year, which
excluded it from further consideration. Instead a stand-alone system was designed
consisting of miniature terminals placed at each ticket counter position linked to
bar-code label printers through a micro-computer and concentrator. As each
passenger with bags to check appeared at the counter, the agent was supposed to
enter the passenger's last name and initial along with the number of bags. This
action created a computer record of the passenger together with a sequence number.
The latter plus a code for the flight number was automatically printed on bar-code
labels, one to be scanned as the passenger boarded the aircraft and the olher(s) for
the baggage tags in case it was desired to identify and remove a bag.
