Answer:

What is Southeastern Pennsylvania Transportation Authority mean?

The Southeastern Pennsylvania Transportation Authority (SEPTA) is a regional public transportation authority that operates bus, rapid transit, commuter rail, light rail, and electric trolleybus services for nearly 4 million people in five counties in and around Philadelphia, Pennsylvania. It also manages projects that maintain, replace and expand its infrastructure, facilities and vehicles.

SEPTA is the major transit provider for Philadelphia and the counties of Delaware, Montgomery, Bucks and Chester. It is a state-created authority, with the majority of its board appointed by the five Pennsylvania counties it serves. While several SEPTA commuter rail lines terminate in the nearby states of Delaware and New Jersey, additional service to Philadelphia from those states is provided by other agencies: the PATCO Speedline from Camden County, New Jersey is run by the Delaware River Port Authority, a bi-state agency; NJ Transit operates many bus lines and a commuter rail line to Philadelphia's Center City; and DART First State runs feeder bus lines to SEPTA stations in the state of Delaware.

SEPTA has the 6th-largest U.S. rapid transit system by ridership, and the 5th largest overall transit system, with about 302 million annual unlinked trips as of fiscal year 2018. It controls 290 active stations, over 450 miles (720 km) of track, 2,350 revenue vehicles, and 196 routes. It also oversees shared-ride services in Philadelphia and ADA services across the region, which are operated by third-party contractors.

SEPTA is one of only two U.S. transit authorities that operates all of the five major types of terrestrial transit vehicles: regional (commuter) rail trains, "heavy" rapid transit (subway/elevated) trains, light rail vehicles (trolleys), trolleybuses, and motorbuses. (The other is Boston's Massachusetts Bay Transportation Authority, which runs ferryboat service as well.)

SEPTA's headquarters are at 1234 Market Street, Philadelphia.
