Modeling a Multi-Modal Megaregion: Arizona’s Sun Corridor Sheds Light on What Drives Industry and Freight: Freight Demand Modeling and Data Improvement Implementation Support

The Arizona Sun Corridor megaregion encompasses portions of five counties that comprise the metropolitan areas served by the Maricopa Association of Governments (MAG) and the Pima Association of Governments (PAG). MAG, PAG, and the Arizona Department of Transportation (ADOT) collaborated to develop a regional freight model that can be integrated within regional and statewide travel forecasting models to support decisionmaking and analysis across the Sun Corridor megaregion. To develop the megaregional freight model, the project team first completed a comprehensive review of freight data sources to determine what data were available and appropriate for the model. With the available data sources identified, the project team developed a number of major model components (including innovative firm synthesis, supply chain, mode choice and transport, and truck tour models). Together these sub-models formed the megaregional freight model. The process included a supply chain model as well as innovative approaches such as accounting for an evolving market of buyers and sellers and a truck touring model that captured trip chaining activities of freight deliveries of differing classes. Major project objectives included: (1) Conducting a comprehensive review of freight data sources to increase capabilities in freight data collection and data analysis; (2) Developing innovative models (e.g., firm synthesis, supply chain, truck tour); (3) Developing an operational, multimodal freight model for the megaregion; and (4) Emphasizing a behavioral approach to model development to assist in coordinated policy development and provide an effective tool for improving freight operations.
