Description of the Multiple Airport Demand Allocation Model

This report describes a computer model, the Multiple Airport Demand Allocation Model, used by the Federal Aviation Administration (FAA) to determine the relative distribution of air passengers between Washington National, Dulles International, and the Baltimore-Washington International Airports for each of a number of airport policy alternatives which are being considered. This model and the report describing it support the FAA's policy statement for the Metropolitan Washington Airports. The model is based upon the understanding that choice of airports, when more than one is available, is determined largely by the relative attractiveness of each facility to air travelers. Attractiveness of each airport is influenced by the location of the facility relative to population and business centers; the speed and cost of airport access, the availability of convenient flight schedules; and airport capacity limitations among other things. All of these factors vary over time as population growth, access systems, and airport capacities change. (Author) Technical Supplement to Rept. no. FAA-AVP-77-36, AD-A052 349.
