The Baltimore region is transitioning from an aggregate to disaggregate travel simulation tool which meets the changing demographic and socioeconomic environment, land use change, and planning needs and challenges in the region. The region's Activity Based Model (ABM) system, known locally as InSITE -- Initiative to Simulate Individual Travel Events, models individual travel choices with maximum behavioral realism. The disaggregate micro-simulation model InSITE consists of a synthetic population generator implemented in PopGen2.0, auxiliary models (truck and external model components), the activity-based travel demand model TourCast, which predicts each individual's long-term choices, daily activity patterns and travel, as well as the traffic assignment module. The simulation is implemented and managed using Cube. The TourCast is programmed with Python and is called by Cube. The activity-based travel demand model (TourCast) structure is as follows:
