PASSENGER WALKING DISTANCE DISTRIBUTION IN SINGLE- AND DUAL-CONCOURSE CENTRALIZED AIRPORT TERMINALS

Walking distance within an airport terminal is one important measure of the level of service provided to passengers. The probability distribution of the walking distance of a passenger is used to compare various single- and dual-concourse centralized configurations for a planned airport terminal defined by a given number of identical gates. The walking distance distribution is obtained by using a simulation technique. Terminal configurations are ranked according to the percentage of passengers who must walk less than a specified maximum distance. The effects of installing moving walkways to reduce the effective walking distance are also analyzed. In the numerical example given, a T-shaped configuration is found to be superior to single, basic dual, and rectangular (with moving walkways) configurations.
