Pittsburgh Regional Transit
Pittsburgh Regional Transit (PRT) is a county-owned public transit agency that operates nearly 100 bus routes that have more than 7,000 stops, the light rail line and two inclines.
The agency is owned by the county, funded by taxpayers and riders, and overseen by a board of directors that is appointed by the County Executive and approved by County Council.
Schedule times and bus stops can change. PRT adjusts schedules four times yearly based on passenger counts, feedback from operators, riders and communities, and other information.
PRT has a goal of improving its on-time performance. The authority considers a bus on time if it’s not more than a minute early or more than five minutes late. By its own measure, buses run on time about two-thirds of the time. During the 2010s, the Port Authority was trying increase on-time performance to 73%.
The transit service encourages the use of their ConnectCard and ConnecTix instead of cash. The ConnectCard is a reusable plastic card that can be purchased at PRT’s Downtown Service Center, Giant Eagle locations and other stores. The authority says that discouraging cash helps speed up trip times.
The Port Authority of Allegheny County was created by the PA General Assembly in the 1950s. They bought 32 privately owned transit companies, including Pittsburgh Railways, which provided mass transit to Carrick.
Early in the coronavirus pandemic of 2020/2021, the Port Authority implemented a host of measures – disinfecting buses daily, riders boarding and exiting through the rear doors, cash customers boarding free, limiting the number of passengers at a time to allow social distancing by riders and requiring face masks. Later, buses returned to regular service, front-door boarding resumed and cash fares were collected.
In 2022, the Port Port Authority renamed itself Pittsburgh Regional Transit (PRT).
Public transit gets people around South Pittsburgh by bus and the T light rail system.
