Existing terminal designs generally require excessive passenger walking distances at the nation's major airports. Airport terminal designs with automated people mover (APM) systems to eliminate this problem are discussed. Data are presented describing the effects of eight existing APM systems on terminal designs and operations. Minimum and maximum walking distances at 18 airport terminals with and without APM systems are presented. The evolution of airport terminal design is also discussed. Two new centralized terminal designs with APM systems to improve airport operations, remote satellites and remote piers, are analyzed. The average passenger travel time was the measure of effectiveness for the analysis. Six prototype designs serving 10 to 30 million annual passengers each are used. The effects of using different percentages of transfer passengers on average travel time and terminal design are also analyzed. Remote satellite design is found to be better when the percentage of transfer passengers is lower but the remote pier is a better design when the percentage of transfer passengers is higher. However, unit terminal design with the APM system is found to be obsolete because its layout is inefficient and difficult for the first-time user.
