The NJTPA extensively uses Geographic Information Systems (GIS) technology that can manage, analyze and present geographic and other data – data that inform much of the agency’s transportation decisions..

This tool incorporates layers of information, including transportation, such as roads, rail lines, bus routes, airports and ports; land use data; aerial photography; and other planning data, like the NJ Office for Planning Advocacy’s centers and planning areas. NJTPA also collects environmental data, including the location of wetlands, parks and historic sites. All of these layers allow NJTPA to assess the potential impacts a project could have on the region as the agency develops plans, programs and planning studies.
