Our data indicates an estimated average traffic volume of 10,009 vehicles per day in Arizona that results in 174,389,603 vehicle-miles traveled per day (≈63.7 billion per year). The traffic stream is comprised of an average of 1 truck for every 10 vehicles. Typical time spent behind the wheel per trip is 32.9 minutes, which already accounts for delays at signals, intersections, and congestion.
Analytical insight
When compared to the US national averages: Arizona's average daily traffic volume is 43% higher than the national average - 10,009 vehicles per day against 6,986 - suggesting more traffic load per road, a critical factor for logistics and site planning. Network-wide, Arizona accounts for about 2.3% of the national total, at 174,389,603 vehicle-miles traveled per day (≈63.7 billion per year). Journey times run 1% lower than the national level, at 32.9 minutes on average. Congestion runs 4% lower than the national level, at a ratio of 18.1% - smoother traffic flow - crucial for traffic control improvement and logistics planning. Arizona carries more traffic than 94% of states nationwide. Its average travel time of 32.9 minutes is longer than 40% of states nationwide.

A significant volume of traffic in Arizona utilizes the highway network. The average highway carries 17,172 vehicles per day, 80% more than the average non-highway road in the same area, which carries 9,535 vehicles per day. That average covers 5,805 highway road miles divided in 21,391 segments (average segment length 1,433 ft), together carrying 87,614,196 vehicle-miles traveled per day (≈32.0 billion per year). That is more highway travel volume than 72% of states nationwide. Trucks constitute 13.9% of highway traffic.
Analytical insight
The concentration of trucks on highways (13.9%) is 7% higher than the national average for similar road classifications. This indicates Arizona serves as a significant freight corridor. For logistics operators, this validates the importance of highway access. By truck concentration, highways here outrank 58% of states nationwide. 70% of states nationwide see fewer highway trucks per day than Arizona's roughly 2,396.

How Arizona compares
Arizona against nearby states
Arizona tracks the 4 states around it closely - no measure in this table sets it far apart from the states immediately next to it, though it has the third busiest roads of the five. The same kind of road, just less of it: traffic per road matches the states around it while the network itself is smaller.
Arizona and the 4 nearest states by centroid distance, with the United States average for scale.
Together, those three counties carry 74.4% of all the vehicle-miles measured in the state.
Ranked by daily vehicle-miles, across the 15 counties in Arizona 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.
The average daily traffic volume is calculated at 10,009 vehicles per day, providing a baseline for daily operations and site assessment.
The driver population in Arizona skews older than 14% of states nationwide.
The average travel time for drivers is 32.9 minutes, offering a standard metric for commute and delivery route planning.
Trucks account for approximately 9.6% of the total traffic mix across all road types, with a significantly higher concentration of 13.9% on highways.
Drivers on Arizona roads have a median age of 43 years, and the median household income of the neighborhoods trips originate from averages $89,913 - useful context for retail siting and customer profiling.
Traffic volumes are typically 6% higher during March–May. Volumes drop to their lowest levels in July, averaging 9,267 vehicles per day - a 7% decrease from the annual average.
