Chattanooga ITS Architecture

The Chattanooga Regional Intelligent Transportation System (ITS) Architecture provides a long-range plan for the deployment, integration, and operation of ITS in the Chattanooga Region. The Regional ITS Architecture allows stakeholders to plan for what they want their system to look like in the long term and then break the system into smaller pieces that can be implemented over time as funding permits. Development of a Regional ITS Architecture encourages interoperability and resource sharing among agencies and allows for cohesive long-range planning among regional stakeholders. Completion and update of the plan is also required by the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) to use federal transportation funds for ITS projects in the Region.

The Chattanooga Regional ITS Architecture was first developed by the Tennessee Department of Transportation (TDOT) in 2003. In June 2010, the Chattanooga-Hamilton County/North Georgia Transportation Planning Organization (TPO), in coordination with TDOT, updated the Chattanooga Regional ITS Architecture. The maintenance plan that was developed in the 2010 Chattanooga Regional ITS Architecture and Deployment Plan set a goal to update the plan every four years. To meet that goal, the Chattanooga-Hamilton County/North Georgia TPO completed a second update of the plan in 2014 and a third update in 2017. The current update was completed in early 2022. The time horizon for this update to the Regional ITS Architecture is 2045. This time horizon aligns with the time horizon for the most recently published version of Chattanooga’s RTP.
