Median parking is necessitated by the scarcity of public parking space in South Philadelphia. The suit says it's the PPA's job "to provide adequate parking services for residents of and visitors to Philadelphia" and to "enforce traffic statutes, ordinances and regulations." The suit adds that the Philadelphia City Code says cars parking on a two-way highway, for which Broad Street qualifies, "shall be positioned parallel to and with the right-hand wheels within twelve (12) inches of the right-hand curb or, in the absence of a curb, as close as practicable to the right edge of the right-hand shoulder."
