New Jersey Road Centerlines GIS Data
The enhanced format version of the statewide road centerlines data set for New Jersey is available for download on this page. The Tritech (formerly Tiburon) formatted version of the road centerlines is also available for download.
The road centerlines builds off of existing NJDOT "NJ Roadway Network" data by expanding coverage to include alleys and private roads; physical segmentation of geographic features at intersections, jurisdictional boundaries and zip code boundaries; and adding attribute values for alternate road names, address ranges, zip codes, zip names, municipality codes, state, surface type, platform elevation level, travel direction, access restrictions, jurisdiction, feature status, date of last update, geocoding attributes, and linear referencing attributes. Update information is available here.
The road centerlines data set is designed to be suitable for general purpose cartography and geocoding. Although linear referencing is provided for with the road centerlines, the NJ Roadway Network, available as a separate data set from NJDOT, continues to be the preferred data set for linear referencing. For more detailed information, please consult the NJ Road Centerlines Data Guide. The data model can be found here: NJ Road Data Model.
The Tran_road_NJ geodatabase contains a feature class and tables structured specifically to support geocoding, linear referencing and change history (not included in current version). The centerlines feature class is also available as a shapefile (does not include support for geocoding, linear referencing and change history).
Tritech (formerly Tiburon) version
The Road_ctr_tritech_NJ shapefile is provided for use with Tritech computer-aided dispatch software and similar products. In the original Tiburon shapefile, alternate road names were represented by duplicate segments of coincident geometry. They are now included as parsed road name elements to support geocoding in an updated attribute table structure. Duplicate segments of coincident geometry are no longer used.
