Our data shows 4,836 vehicles per day on the average road in Maine, and 32,675,550 vehicle-miles traveled per day (≈11.9 billion per year) across its 8,426 miles of monitored roads. Trucks are 8.7% of traffic, close to the 9.3% across the US.

Longer trips than 87% of states nationwide

Maine's average daily traffic volume is 31% lower than the national average - 4,836 vehicles per day against 6,986 - suggesting less traffic load per road - lighter roads for freight, but less passing trade for roadside retail. Across the whole network, that travel is about 0.4% of the national total. By volume, Maine's 4,836 vehicles per day trails 74% of states nationwide.

At 34.6 minutes, the average travel time matches the national level closely. Its average travel time of 34.6 minutes is longer than 87% of states nationwide.

At 23% lower than the national level, the 14.6% congestion ratio signals smoother traffic flow - crucial for traffic control improvement and logistics planning.

Highway vs. Non-Highway Traffic Analysis

Drivers’ average income$80,051

A significant share of driving in Maine, 35% of vehicle-miles, happens on highways. The average highway carries 8,989 vehicles per day, 101% more than the average non-highway road in the same area, which carries 4,469 vehicles per day.

Highways make up 16% of the monitored road miles (1,384 miles, 9,019 segments), so they carry more than their share: 11,559,445 vehicle-miles traveled per day (≈4.2 billion per year).

Fewer highway trucks than 86% of states nationwide

At 12.3%, highway truck share is 6% lower than the national average. The highway traffic mix is typical for the US: neither freight- nor commuter-dominated.

58% of states nationwide see a higher highway truck share than Maine's 12.3%. Maine's highway truck count is lower than 86% of states nationwide, at roughly 1,110 trucks per day.

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.
