NJ Geographic Information Network

Roads

The road centerlines builds off of the existing NJ Department of Transportation (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.

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 dataset from NJDOT, continues to be the preferred dataset for linear referencing.

At the present time, there are known issues with the linear referencing systems contained within this data. The most prevalent issues appear to be with the Parent linear referencing system. It is strongly recommended that users utilize the NJDOT Roadway Network data for linear referencing at this time. NJOGIS is currently working to correct the linear referencing issues.

This file geodatabase contains the entire NJ Road Centerlines publication data model. This includes all feature classes and supporting tables.

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.
