<正>Regional rail service has played an integral role in the development of the New York metropolitan area over the past century. The multiplicity of jurisdictions and agencies make planning for future growth very complex, and funding shortfalls force implementation timetables to extend far into the future. However, by focusing on high-priority "mega-projects" that tie critical elements of the region’ s transport networks and economic centers together and by utilizing a strategy of "Transit-Oriented Developments" in suburban growth areas, urban planners and policy makers can leverage existing infrastructure and maximize the economic viability of rail transit and land investments by both public and private sectors.
