Thank you for your interest in the Port Authority of Allegheny County's transit schedule data. Our data is published in the General Transit Feed Specification (GTFS) format for developers to use and represents static schedule and route information.
This information is updated quarterly to reflect new schedule changes (which usually take place in March, June, September and November). Generally this information is available several weeks prior to the effective date of schedule changes.
Port Authority also makes certain mapping data, including the location of stops, stations and other material information relevant to Port Authority’s transit system, in Geographic Information Systems (GIS) format for developers to use. Like the transit schedule data, the GIS mapping data is updated on a quarterly basis.
Use of the GTFS and/or GIS data is subject to the terms and conditions of the Port Authority's License Agreement.
