Innovations in MAG Activity-Based Model and Incorporation of Travel Time Reliability in Modeling Procedures (December 20, 2017)


Date: December 20, 2017

Description: The session will focus on the innovative features and implementation details of the Maricopa Association of Governments Activity-Based Model. Special attention will be given to incorporation of travel time reliability metrics in the model and the model implementation details such as software development and hardware architecture, data requirements and approaches for results analysis and visualization. The presenters will describe activity generation and tour formation, with an emphasis on supply side of the activities, sub-model for escorting children to school, improved models for work arrangements, and features designed for future integration with dynamic traffic assignments. Next steps in model development will be discussed as well.
