Our data shows 6,061 vehicles per day on the average road in Louisiana, and 121,368,958 vehicle-miles traveled per day (≈44.3 billion per year) across its 23,027 miles of monitored roads. Trucks are 11.2% of traffic, more than the 9.3% across the US.

Shorter trips than 86% of states nationwide

At 6,061 vehicles per day, the average road in Louisiana carries somewhat less traffic than the national average of 6,986 (13% less) - a factor worth weighing in site selection and logistics planning. Across the whole network, that travel is about 1.6% of the national total. 52% of states nationwide see less traffic than Louisiana's 6,061 vehicles per day.

Journey times here (31.8 minutes on average) closely track the national level. On travel time, Louisiana runs shorter than 86% of states nationwide.

The congestion ratio of 17.3% runs slightly lower than the national level (8% lower).

Highways carry about half of all travel in Louisiana, 49% of vehicle-miles. The average highway carries 12,792 vehicles per day, 132% more than the average non-highway road in the same area, which carries 5,524 vehicles per day.

With 19% of the road miles (4,444 miles in 21,638 segments), highways punch above their length, carrying 60,063,364 vehicle-miles traveled per day (≈21.9 billion per year).

That is more highway travel volume than 52% of states nationwide.

Higher highway truck share than 86% of states nationwide

At 16.1%, highway truck share is 23% higher than the national average. Highways here lean toward freight, so highway access is a real asset for logistics operators.

86% of states nationwide see a lower highway truck share than Louisiana's 16.1%. Louisiana's highway truck count is higher than 76% of states nationwide, at roughly 2,053 trucks per day.

Drivers from lower-income areas than 84% of states nationwide

Compared to highways, non-highway routes see 60% fewer trucks by share.

Non-highway congestion (16.9%) runs slightly lower than the national level (8% lower).

Trip origins here have lower average income than 84% of states nationwide. 74% of states nationwide have an older driver population than Louisiana.

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.
