Depending on how the end space is used and how much area is taken away from circulation for holdrooms, the usage percentage may be as low as 80%. An assessment of the concourse gate allocation and loading structure will help determine what percentage to use. Typically 85% is a good starting point for linear pier concourse design. Moving Walkways Moving walks transport passengers and their baggage on a moving platform horizontally or at slight inclines. This system can either be manufactured as a pallet or moving belt style. A series of continuous flat metal plates jointed together in a horizontal manner to form the walk- way describes the pallet system. The moving belt style consists of a series of metal rollers over which a rubber walking surface is placed, sometimes resulting in a bouncy feel when walking over the surface. As a general planning standard, moving walkways are typically recommended when walking distances exceed approximately 1,000 feet between the major functions of the terminal complex. These walkways may be utilized from parking facilities to ticketing/baggage claim areas, as access to ground transportation stations, in connectors between concourse/terminal to terminal, and security screening checkpoints to major concourse nodes and/or the furthest concourse gate. When planning for moving walkways, factors that influence the layout consist of the volume of passengers to be transported, whether concourses are single or double loaded, and locations of major concessions nodes. Moving walkways are typically installed in pairs traveling in opposite directions and designated by pallet widths or the area the passenger travels on. Depending on the manufacturer, a pallet range for an airport moving walkway is 40 inches to as much as 56 inches, Figure 77. NBEG calculation matrix.

The overall required width for the moving walkway ranges from 5 feet 6 inches to 7 feet, and lengths vary between manufacturers. Figure 78 represents a typical moving walkway with common dimensional criteria. The default widths used for double moving walkways are 12 feet and 15 feet, which allows for an additional 1-foot buffer between the two walkways.
