Above is my complete regional rail transit network planned for the Greater Pittsburgh region. These lines fall into a hierarchy. Regional rail, identified with the white lines, will serve the more dense urban and suburban areas, while light rail (green, blue, and yellow) and heavy rail (red and orange) will concentrate mainly on the urban core areas within Allegheny County.
Part four will identify the areas where Bus-Rapid Transportation will be the most suitable, primarily in places north of and south of the city. Also outlined in part four will be the regional transit access points for each line as well as which access points will serve as inter-modal transportation centers or hubs.
