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 “RTP” refers to the models adopted in February 2020 as part of Regional Transportation Plan element of The Atlanta Region’s Plan. The base year for this Plan is 2015, and the initial horizon years are 2020, 2030, 2040, and 2050. Over time, as new regional projects are planned, the horizon year models will be updated. Updated models will be released using the prefix “TIP” and an identifying iteration, such as “TIP1” for the first round of TIP project updates. The base year model (RTP 2015) will not change.
