US 19 Corridor Study. Cranberry Township Area, Pennsylvania.

The US 19 Transportation and Land Use study used scenario planning to determine a blueprint for future needs within the Pittsburgh region’s fasted growing corridor.

The US 19 Transportation and Land Use Study involved identifying transportation deficiencies and optimal solutions for two heavily congested corridors spanning three counties, seven municipalities, two PennDOT districts, and one MPO. The study used scenario planning to evaluate the impacts of various transportation and land use solutions in order to meet the long term needs of the study area. Scenarios included reducing future development, better multi-modal connections, and traditional roadway widening The locally preferred alternative resulted in a series of phased improvements for the corridor. The analysis for the project relied on a mix of traditional operational analyses and development of a hybrid macro/microscopic model with dynamic traffic assignment that was used to evaluate this highly congested corridor.
