Roadway Information and Traffic Monitoring

Annual Average Daily Traffic Flow

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.
(The AADTF application is a joint effort between Federal Highway Administration and NJDOT Bureau of Transportation Data and Safety.)
