The average monitored road in Alaska carries 4,749 vehicles per day. Across its 2,684 miles of monitored roads, that adds up to 10,445,061 vehicle-miles traveled per day (≈3.8 billion per year). About 1 in 15 vehicles is a truck, fewer than the 1 in 11 across the US.

Quieter roads than 76% of states nationwide

Alaska sees 32% lower average daily traffic volume than the national average (4,749 vehicles per day against 6,986), suggesting less demand on each road - lighter roads for freight, but less passing trade for roadside retail. Network-wide, Alaska accounts for about 0.1% of the national total of vehicle-miles. Alaska carries less traffic than 76% of states nationwide.

The average trip takes 34.0 minutes, on par with the national level. Its average travel time of 34.0 minutes is longer than 70% of states nationwide.

The congestion ratio of 14.9% is 21% lower, pointing to smoother traffic flow than the national level - crucial for traffic control improvement and logistics planning.

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.
