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, Ohio, United States, and the surrounding suburbs of Cuyahoga County. RTA is the largest transit agency in Ohio, providing over 44 million trips to residents and visitors of the Cleveland area in 2010. RTA owns and operates the RTA Rapid Transit rail system (better known as "The Rapid"), which consists of one heavy rail line (the Red Line) and two interurban light rail lines (the Blue, Green and light-rail Waterfront extension line). 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 are 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."
