Activity Based Model

Welcome to the Data Download Portal for the Atlanta Regional Commission’s Activity-Based Model. Below are direct download links to the available model data and information. The prefix “MTP24” refers to the 2050 Metropolitan Transportation Plan (MTP), adopted in February 2024. The base year for this plan is 2020 with intermediate years of 2030, 2033, 2040, and a horizon year of 2050. Updated conformity model series are reflected with amendments to the Transportation Improvement Program (TIP) and MTP. For example, “TIP3” reflects the third amendment to the TIP/MTP.
