Chattanooga ITS Architecture

Chattanooga Regional Intelligent Transportation System (ITS) Architecture Overview,  the Chattanooga Regional ITS Architecture is a long‑range plan that guides how Intelligent Transportation Systems (ITS) are deployed, integrated, and operated in the Chattanooga region. The architecture helps agencies coordinate their systems, plan for future needs, and invest in ITS projects over time as funding becomes available.

A regional ITS architecture also supports interoperability and resource sharing among agencies. It encourages consistent long‑range planning and ensures that the region meets Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) requirements for using federal transportation funds on ITS projects.

History and Updates

• The Tennessee Department of Transportation (TDOT) developed the first Chattanooga Regional ITS Architecture in 2003.
• The Chattanooga-Hamilton County/North Georgia Transportation Planning Organization (TPO), working with TDOT, updated the plan in 2010. This update included a maintenance strategy that recommended revising the plan every four years.
• Following that schedule, the TPO completed additional updates in 2014 and 2017.
• The most recent update was finished in early 2022.

Planning Horizon

The current ITS Architecture uses a planning horizon that extends to the year 2045. This matches the time horizon of the region’s most recently published Regional Transportation Plan (RTP).
