Atlanta Regional Commission

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 related models and information. The prefix "MTP24" refers to the Atlanta Metropolitan Transportation Plan, 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. Over time, as new regional projects are planned, the intermediate and horizon year models will be updated. Updated models will be released using the prefix "Amd" and an identifying iteration, such as "Amd 1" for the first round of project updates.
