A typical monitored road in Oregon sees 5,908 vehicles per day, while its 17,209 miles of monitored roads together handle 86,863,904 vehicle-miles traveled per day (≈31.7 billion per year). About 1 in 11 vehicles is a truck, in line with the US (9.3%).

Longer trips than 78% of states nationwide

Oregon sees 15% lower average daily traffic volume than the national average (5,908 vehicles per day against 6,986), suggesting less demand on each road - a factor worth weighing in site selection and logistics planning. Network-wide, Oregon accounts for about 1.1% of the national total of vehicle-miles. 52% of states nationwide see more traffic than Oregon's 5,908 vehicles per day.

The average trip takes 34.3 minutes, on par with the national level. On travel time, Oregon runs longer than 78% of states nationwide.

Congestion is somewhat lower than the national level, at a ratio of 16.6% (12% lower) - relevant for traffic control and delivery planning.

Highways make up 24% of the monitored road miles (4,154 miles, 28,017 segments), so they carry more than their share: 48,700,556 vehicle-miles traveled per day (≈17.8 billion per year).

Fewer highway trucks than 68% of states nationwide

At 12.0%, highway truck share is 8% lower than the national average. The highway traffic mix is typical for the US: neither freight- nor commuter-dominated.

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.
