New equipment technologies may be put into service. The entire baggage system must be able to accommodate any or all of these changes efficiently and cost effectively. To do that, the baggage system demands flexibility throughout the terminal design. If the terminal is expanded, for example, each new module must also have a baggage system, including corridors and zones. But the expansion doesn't stop there.
New modules require additional baggage rights of way throughout the terminal.
To handle this domino effect, the terminal design must anticipate that expansion with extra wide, initially unused baggage routes starting near the check-in counters to accommodate future rights of way. All of these different users must be served by the terminal's circulation systems. Planning the public approach to a terminal is one of the most challenging aspects of airport design. All of these approaches must give people a ceremonial sense of arrival at the terminal and functionally point them in the right direction. Sometimes, these two systems are integrated into each other.
