Public transit is integral to a multimodal transportation system. In particular, an effective public transit system helps the TPO achieve the regional transportation plan goal of connecting communities to recreational, social, and economic opportunities by providing multimodal travel options to activity and economic centers. The Chattanooga Area Regional Transportation Authority (CARTA) currently provides fixed-route, mass transit service with a fleet of buses and shuttles in the Chattanooga area. Additionally, CARTA operates paratransit service (Care-A-Van), dial-a-rides, and an incline railway. Other public transit operators in the TPO area include the Southeast Tennessee Human Resource Agency (SETHRA), which provides demand-response transportation to, from, and within the non-urbanized portion of Hamilton County, as well as several operators from north Georgia counties (Dade County Transit, Catoosa Trans-Aid, and Walker Transit) that provide similar demand-response transportation. CARTA is the only designated recipient of Federal Transit Administration funding in the TPO area. As such, CARTA and the TPO coordinate on transit planning activities for the entire TPO area.
