Modeling

Activity-Based Model (ABM)

The Atlanta Regional Commission’s ABM is the regional Travel Demand Model associated with the current Regional Transportation Plan (RTP), The Atlanta Region’s Plan.  ARC’s ABM is based on the Coordinated Travel Regional Activity-Based Modeling Platform (CT-RAMP) which addresses both household-level and person-level travel choices including intra-household interactions between household members.  The ABM reflects and responds to detailed demographic information, including household structure, aging, income changes, and other key attributes. ARC's ABM is part of a fully integrated transport land use model involving the Production Exchange Consumption Allocation System (PECAS) model which is used to create small area forecasts from the regional control forecasts produced by the REMI model.  ARC’s ABM was calibrated and validated using the 2011 Regional Household Travel Survey and the 2009-2010 Regional On-Board Transit Survey.

Motor Vehicle Emission Simulator (MOVES)

Vehicle miles traveled (VMT) estimates from the ARC ABM are combined with emission factors from EPA’s MOVES to calculate the total transportation sector contribution of the Air Quality of the Atlanta Region involving nonattainment atmospheric pollutants.

Model Users Group (MUG)

The Atlanta Region’s MUG serves as the forum for all users of the ARC Travel Demand Model. The goals are to educate, inform and improve travel demand forecasting as part of the regional transportation planning process. MUG membership consists of staff from local, regional and state agencies, in addition to members of academia and consulting.
