Our data shows 5,932 vehicles per day on the average road in Alabama, and 141,682,089 vehicle-miles traveled per day (≈51.7 billion per year) across its 27,950 miles of monitored roads. About 1 in 9 vehicles is a truck, in line with the US (9.3%).

Shorter trips than 84% of states nationwide

Alabama's average daily traffic volume is 15% lower than the national average - 5,932 vehicles per day against 6,986 - suggesting less traffic load per road - a critical factor for logistics and site planning. In total volume terms, its road network carries about 1.9% of the national total of vehicle-miles. 50% of states nationwide see less traffic than Alabama's 5,932 vehicles per day.

Journey times here (31.8 minutes on average) closely track the national level. 84% of states nationwide have a longer average travel time than Alabama's 31.8 minutes.

Congestion runs 18% lower than the national level, at a ratio of 15.5%, which means smoother traffic flow - relevant for traffic control and delivery 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.
