Our data shows 3,802 vehicles per day on the average road in Wisconsin, and 133,024,389 vehicle-miles traveled per day (≈48.6 billion per year) across its 35,288 miles of monitored roads. About 1 in 10 vehicles is a truck, in line with the US (9.3%).
Wisconsin sees 46% lower average daily traffic volume than the national average (3,802 vehicles per day against 6,986), suggesting less demand on each road - lighter roads for freight, but less passing trade for roadside retail.

At 32.2 minutes, the average travel time matches the national level closely. On travel time, Wisconsin runs shorter than 79% of states nationwide.
The congestion ratio of 12.6% is 33% lower, pointing to smoother traffic flow than the national level - fewer delays make delivery windows more reliable.
