The South Florida Regional Transportation Authority (SFRTA) is a tri-county public transit authority operating out of Pompano Beach, Florida, serving Miami-Dade, Broward and Palm Beach counties. The organization was created on July 1, 2003 by the Florida Legislature and enacted by the Florida Department of Transportation. Replacing the pre-existing Tri-County Commuter Rail Authority, the goal of incorporation was to expand cooperation between the Tri-Rail commuter rail service and the existing county public transport authorities: Broward County Transit, Miami-Dade Transit, and Palm Tran. Tri-Rail is solely operated by SFRTA.
SFRTA's mission statement is "To coordinate, develop and implement, in cooperation with all appropriate levels of government, private enterprise and citizens at-large in the community, a viable regional transportation system in South Florida that endeavors to meet the desires and needs for the movement of people, goods and services."
In November 2011, the Federal Transit Administration (FTA), through its TIGGER III Program, awarded $5.7 million to SFRTA for its sustainable stations project. The project involves installation of solar panels at stations that will provide 100% of the station's energy, while sending excess energy to the main power grid and store daytime energy for lighting needs at night.
