MAG Behavioral Freight Model and Regional Microsimulation Model

Sunday, January 1, 2017
Dynamic Traffic Assignment (DTA)

Presentation 1: MAG Behavioral Freight Model: The Maricopa Association of Governments (MAG), Arizona Department of Transportation (ADOT), and Pima Association of Governments (PAG) in close cooperation with FHWA developed and implemented an innovative multimodal mega-regional freight model. The project was a part of the FHWA SHRP2 C20 Implementation Assistance Program. This model was designed for evaluation of freight planning policies and economic development scenarios relevant to the Arizona Sun Corridor megaregion. The model incorporates an agent-based behavioral approach to freight modeling and includes firm synthesis and evolution, supply chain with innovative approaches to efficient modeling of buyers and suppliers behavior, transport and mode choice, tour-based truck models and powerful visualization tools. The presentation covers the main sub-models and visualization tools, freight data issues and lessons learned throughout the project. Presentation 2: MAG Regional Microsimulation Model: The Maricopa Association of Governments (MAG) has developed a region-wide microsimulation model. The model has been utilized for the analysis of various operational improvements and planning scenarios, including large sub-area studies. The presenters discuss model input data, challenges in the course of model development, and validation processes and results. Demonstrations of some of the model applications are presented as well. The presentation concluded with visualization tools, including Interactive maps for visualization of the time-dependent input data and simulated results
