Greater Cleveland Regional Transit Authority

The Greater Cleveland Regional Transit Authority (officially the GCRTA, but historically and locally referred to as the RTA) is the public transit agency for Cleveland and the surrounding suburbs of Cuyahoga County, Ohio, United States. RTA is the largest transit agency in Ohio, with a ridership of 24,519,200, or about 79,200 per weekday as of the second quarter of 2026.

RTA owns and operates the RTA Rapid Transit rail system (called "The Rapid" by area residents), which consists of one heavy rail line (the Red Line) and three light rail lines (Blue, Green, Waterfront). The bulk of RTA's service consists of buses, including regular routes, express or flyer buses, loop, and paratransit buses. In December 2004, RTA adopted a revised master plan, Transit 2025, in which several rail extensions, bus line improvements and transit oriented developments were discussed.

RTA's major predecessor, the Cleveland Transit System, was the first transit system in the western hemisphere to provide direct rapid transit service from a city's downtown to its major airport.

In 2007, RTA was named the best public transit system in North America by the American Public Transportation Association, for "demonstrating achievement in efficiency and effectiveness."
