CT-RAMP family of activity-based models

This paper describes the structure, implementation, and application experience of seven different regional activity-based models (ABMs) that share the Coordinated Travel - Regional Activity Modeling Platform (CT-RAMP) design and software platform. The CT-RAMP models are characterized by a number of features, including a full simulation of travel decisions for discrete households and persons; explicit tracking of time in half-hourly increments and use of time constraints on the generation of travel, as well as explicitly modelled intra-household interactions across a range of activity and travel dimensions. These important features allow for greater behavioral realism in representing the response to numerous transportation policies. The first ABM of the CT-RAMP family was developed in 2004 for the Mid-Ohio Regional Planning Commission (MORPC) located in Columbus, OH, and was adapted for the Tahoe Regional Planning Agency (TRPA) in 2006. The third and forth ABMs were completed in 2009 in parallel for the Atlanta Regional Commission (ARC) and the San Francisco Bay Area's Metropolitan Transportation Commission (MTC). Three new ABMs are currently being developed, including: for the San Diego Association of Governments (SANDAG); for the Maricopa Association of Governments (MAG) in Phoenix, AZ; and for the Transportation Master Plan Team (JTMT) in Jerusalem, Israel. Each implementation of the CT-RAMP model included refinements to address specific regional conditions and additional advanced features compared to previously developed models. These features are explained in this paper, and analysed in the context of model application for different transportation projects and policies.
