Busier roads than 90% of states nationwide

New Jersey's average daily traffic volume is 27% higher than the national average - 8,886 vehicles per day against 6,986 - suggesting more traffic load per road - a busier backdrop for retail sites, at the cost of slower access.

How to read these road counts
  • The first number is AADT, annual average daily traffic: the vehicles passing a point on an average day, both directions combined and trucks included. On a divided highway both carriageways are added together.
  • Traffic changes along a road, with more near interchanges and towns and less in open country. Every figure for a road describes its busiest stretch in the county, so the two rankings show the same numbers for the same road.
  • The second number is the trucks on that stretch, a part of its AADT. The bar splits the AADT into cars and light vehicles (blue) and trucks (amber).
  • See segment-level AADT for any road on TrafficZoom.
