Puerto Rico Metropolitan Bus Authority

Autoridad Metropolitana de Autobuses was created as a public corporation on May 11, 1959. The operations would later be integrated into the Department of Transportation and Public Works in 1973 and the Integrated Transit Authority in 2014. It is the second oldest public transport authority in America, behind New York's Metropolitan Transportation Authority.

AMA is one of three major public transportation systems serving the San Juan metropolitan area, along with Tren Urbano and the Cataño Ferry.

AMA provides bus transportation in the San Juan metropolitan area—which includes the municipalities of San Juan, Guaynabo, Bayamón, Trujillo Alto, Cataño, Toa Baja, Carolina, and Loíza—through a network of 32 fixed bus routes.

Most routes operate Monday through Friday from 5AM to 9PM; and Saturdays and holidays from 6:00AM to 8:00PM. Only routes E30, E40, and T3 offer Sunday service, along with Tren Urbano and the Cataño Ferry.

Most bus stops are identified with a "Parada" (English: stop) green sign.

The regular service fare is $0.75 per ride. The only bus routes with a different fare are Routes E20 and E30 with a $2.00 cost per ride. Reduced fares are available for students, seniors, and people with disabilities.

All buses require exact change in coins or the use of a magnetic fare card available at Tren Urbano stations.

ATI manages the operation of thirty-two bus routes in the San Juan metropolitan area; twenty-four operated by AMA and eight by First Transit. The design of the bus network includes four service categories to guide the customers and improve the coordination between buses, ferry, públicos, municipal buses, and Tren Urbano.[3]
