The institutionally-fragmented nature of surface and air transportation planning in the Northeast Corridor Megaregion (NECM) has significantly hampered the NECM�s ability to undertaken essential multi-modal transportation investments in timely and productive manner. Part of this problem is technical. Each of the 15 separate metropolitan planning organizations (MPOs) that have transportation planning jurisdiction along the 460 miles of I-95 that connect Boston to Washington D.C. uses a different transportation planning modeling and forecasting system. Even if the various MPOs in the Northeast Corridor region wanted to better collaborate in making megaregional-scale investment decisions, their disparate planning and modeling technologies would get in the way. This proposal will attempt to mitigate these technical difficulties by developing a collaborative megaregional-scale platform for comparing and evaluating alternative, multimetropolitan surface and air transportation investments. The proposed project will take two years to complete. Project activities during the first year will involve inventorying the transportation planning packages and databases currently in use by MPOs in the Northeast corridor region; building a new, megaregional scale transportation analysis zone (TAZ) zone system, and populating it with appropriate socio-economic and land use data; using VISSUM to build interacting highway, passenger rail, commuter rail, passenger air, and public transit networks that function at the mega-regional and metropolitan scales; and calibrating a complete 4-step transportation planning model for the most recent year (e.g., 2015) for which data is available. |
