Data & Maps

The NJTPA regional databank is a digital repository for all transportation and related data, stored and maintained on the NJTPA’s computer network. The regional databank assists staff, agency partners and subregions in planning initiatives by providing accurate, accessible transportation and related datasets necessary for informed analysis, decision-making and reporting.

Datasets are made available to partner agencies, subregions and the general public via posting on the Internet and fulfillment of individual data requests. Staff produces tables, maps, and analyses to inform decision-makers, allowing the databank to support numerous planning tasks. The NJTPA also shares various data sets and map layers with other agencies. These data sources have been divided into the categories listed on the left of this page, and described below.

Travel/Performance Data

Much of the planning data used by NJTPA relates to the travel experience for users and the overall performance of the transportation system. Examples of datasets that are maintained in the databank include:

  • management systems data (CMS, NJDOT crash records, etc.);
  • historic and current traffic counts; bicycle and pedestrian indices;
  • outputs from the North Jersey Regional Transportation Model.

Demographics
Where people live and work helps to identify the origins, destinations, and demand for travel throughout the region. NJTPA uses several sources of demographic data, including decennial census data (such as journey-to-work), intercensal surveys (such as the American Community Suvey), and demographic forecasts.

Maps/GIS Data
Much of the data that inform transportation decisions describe physical locations in the region and are maintained in a geographic information system (GIS). Examples include framework transportation layers (road network, rail lines, ports, bus routes, airports), land use data, aerial photography, and other planning layers (e.g., NJ Office of Smart Growth centers and planning areas). NJTPA also collects and maintains GIS layers that reflect various environmental features, such as wetlands, parks, and historic areas. These GIS layers are used, via overlay analyses, for the purposes of assessing potential project impacts as part of the development of plans, programs, and various planning studies at the NJTPA.
