56 Airport Passenger Terminal Planning and Design bags. Feed conveyors can be located on a different floor level, or from some distance, and may feed the claim unit from either above or below. This capability provides flexibility in location; but, with separate feed conveyors, there is the possibility of jams if oversized bags or bags with loose straps are accidentally loaded. The minimum width of these units is 18 to 25 feet, depending on the manufacturer, but is often wider due to the location of structures and the feed conveyors. Sloped bed units can also be con- figured to allow flow-through passenger circulation, which may be advantageous in some terminal configurations, especially for larger claim units. Although sloped bed units have more baggage storage capacity, the effective amount of this capacity is often less than expected unless airline/ airport personnel manually reposition bags to optimize bag capacity. Odd-Sized or Oversized Baggage Facilities should also be provided for odd-sized or oversized baggage, such as golf clubs, skis, and packages that are too large to fit on the baggage claim units or may cause jams on feed conveyors. Odd-/Over-sized Baggage is usually handled in one of three ways: Oversized Belt: An extra wide conveyor, anywhere from 45 to 65 inches in width, transports odd-sized bags from the baggage off-load area to the baggage claim hall generally between two claim units or against an exterior wall of the claim area. This conveyor system can be flat, incline, or decline before entering the claim area, but it is recommended that no turns be used in the odd-sized system. Oversized Slide: Roll-up doors, between 6 to 10 feet wide and at least 5 feet high with a stain- less steel slide, can be used to deliver oversized bags to the claim area. This system usually func- tions effectively only when the cart is unloaded at the same level as the claim area similar to the flat plate claim arrangement. Manual Lay Down: When it is not practical to include either a slide or belt system, airline employees can take odd-sized luggage from the secured side to the non-secured side by using an airport access door usually adjacent to the claim area for passenger retrieval. Retrieval and Peripheral Areas The total amount of the retrieval and peripheral areas is ultimately determined by the num- ber of passengers expected to be near the claim unit and the desired LOS. These areas include the active claim depth along the unit (retrieval area), the depth for others in the traveling party, plus a circulation zone to and away from the claim unit peripheral area. It has been found, however, that 15 feet is typically the minimum recommended depth for the retrieval and adjacent peripheral areas at all but the smallest airports. This minimum depth results in a minimum separation of 30 feet between adjacent claim units or the "arms" of a flat plate claim. For international claim areas where there is a high percentage of passengers using bag trolleys, a 35- to 40-foot minimum separation is recommended. These dimensions assume an obstruction-free area to allow ease of circulation. Columns, bag cart racks, and other structures should not be within the retrieval area. Objects located within the peripheral area usually will require additional separation. A minimum separation between the claim unit and walls, or bag trolley racks is recommended to be 15 to 20 feet for domestic claim units and 20 to 25 feet for international claim units.

Baggage Claim Model 57 At airports having "positive claim," that is, a railing or wall around the claim units so that a security guard can check if a person has the correct bag, may require additional circulation for queuing at the controlled claim area exits. Additional area, outside of the peripheral claim area, needs to be provided for access to the claim area, circulation to ground transportation counters (rental cars, public transportation, commercial vans, etc.), seating for meeters/greeters and passengers waiting for transportation pick-up, etc. The dimensions of this circulation zone are dependent on projected passenger vol- umes and functions adjacent to the claim units, such as rental car counters.
