A typical monitored road in Kentucky sees 4,696 vehicles per day, while its 27,673 miles of monitored roads together handle 118,801,454 vehicle-miles traveled per day (≈43.4 billion per year). Trucks are 12.1% of traffic, more than the 9.3% across the US.

Shorter trips than 90% of states nationwide

Kentucky's average daily traffic volume is 33% lower than the national average - 4,696 vehicles per day against 6,986 - suggesting less traffic load per road - lighter roads for freight, but less passing trade for roadside retail. In total volume terms, its road network carries about 1.6% of the national total of vehicle-miles. 78% of states nationwide see more traffic than Kentucky's 4,696 vehicles per day.

The average trip takes 31.7 minutes, on par with the national level. 90% of states nationwide have a longer average travel time than Kentucky's 31.7 minutes.

The congestion ratio of 14.7% is 22% lower, pointing to smoother traffic flow than the national level - relevant for traffic control and delivery planning.

Highway vs. Non-Highway Traffic Analysis

Trafficvehicles per day10,824
Trucks15.9%
Average travel time36.6 min
Congestion ratio28.2%
Drivers’ average age46.9 yrs
Drivers’ average income$72,048

A little more than half of the driving in Kentucky happens on highways: 61% of all vehicle-miles. The average highway carries 10,824 vehicles per day, 168% more than the average non-highway road in the same area, which carries 4,042 vehicles per day.

Highways make up 24% of the monitored road miles (6,713 miles, 30,961 segments), so they carry more than their share: 72,174,037 vehicle-miles traveled per day (≈26.3 billion per year).

That is more highway travel volume than 62% of states nationwide.

Higher highway truck share than 80% of states nationwide

Highway truck concentration here runs 21% higher than the national average, at 15.9%. Highways here lean toward freight, so highway access is a real asset for logistics operators.

80% of states nationwide see a lower highway truck share than Kentucky's 15.9%. By raw truck volume, Kentucky carries fewer highway trucks than 58% of states nationwide.

Trafficvehicles per day4,042
Trucks6.1%
Average travel time31.3 min
Congestion ratio13.9%
Drivers’ average age46.1 yrs
Drivers’ average income$71,427

A significant share of driving in Kentucky, 39% of vehicle-miles, happens on local roads. The average non-highway road carries 4,042 vehicles per day.

Local roads make up 76% of the monitored road miles (20,960 miles in 290,103 segments) but carry less than their share of travel: 46,627,415 vehicle-miles traveled per day (≈17.0 billion per year). The truck share on non-highway roads is 6.1%.

Drivers from lower-income areas than 92% of states nationwide

Compared to highways, non-highway routes see 61% fewer trucks by share.

At 24% lower than the national level, the non-highway congestion ratio of 13.9% signals easier movement on local roads.

Kentucky's average driver income is lower than 92% of states nationwide. The driver population here skews older than 64% of states nationwide.

Busiest counties in Kentucky

Kentucky's three busiest counties account for 21.9% of all the vehicle-miles measured in the state.

Ranked by daily vehicle-miles, across the 120 counties in Kentucky with a published traffic page. Vehicle-miles is total travel, so this ranks by traffic MOVED rather than by how busy a typical road is.

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.
