2012 Airport Travel Model Update and Data Collection
The Maricopa Association of Governments (MAG) is the metropolitan planning organization for the Phoenix area. The current MAG Regional Travel Forecasting Model is a state-of-the-practice, trip-based, four-step model that estimates travel demand for automobiles and trucks for an average weekday. MAG is developing a regional activity-based model. Both models emphasize special travel generator sub-models such as the Arizona State University sub-model, Phoenix Sky Harbor International Airport (PHX) sub-model, and planned special events models. The special travel generators play a crucial role in regional travel patterns. To update and recalibrate these models, MAG conducted a series of innovative, large-scale special generator surveys, including a regional airports survey, an Arizona State University survey, and a special events survey. Results of the special events survey were presented in previous Transportation Research Board publications. This paper details the data collection approach and methodology used for the regional airports survey, and elaborating on the innovative data collection techniques used to execute the survey.
