Chattanooga Regional Intelligent Transportation System (ITS) Architecture Overview

The Chattanooga Regional Intelligent Transportation System (ITS) Architecture is a long-range plan for the Chattanooga region.

It guides how agencies deploy, integrate, and operate Intelligent Transportation Systems (ITS) over time.

The architecture helps agencies coordinate their systems, plan for future needs, and invest in ITS projects as funding becomes available.

It also helps Chattanooga-area agencies work together and share resources.

It encourages consistent long-range planning and helps the region meet federal transportation funding requirements.

These requirements come from the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA).

These requirements apply when agencies use federal transportation funds to support ITS projects.

Planning Horizon
