Milepost Dataset

The New Jersey Department of Transportation’s Geographic Information System (GIS) consists of many data sources, including accidents, construction, congestion, road inventories, pavements and safety, used to produce maps that support the Department’s work in planning, highway, rail, aviation and maritime. Users of these applications can locate areas of interest, view and interact with NJDOT's GIS data, and query related transportation data, including Annual Average Daily Traffic Flow (AADTF).

Annual Average Daily Traffic Flow (AADTF)

The New Jersey Department of Transportation collects traffic data at over 1,600 station locations along all Interstate, U.S. and N.J. Routes throughout the State of New Jersey. This map represents the estimated Annual Average Daily Traffic (AADT) values based on the most current station data available. The AADT Flow layer data is displayed in six (6) groups, five (5) representing graduated AADT ranges and one (1) representing no station data. The traffic information is used for planning, design, maintenance and general administration of the roadway systems.
