We would like to inform you of some facts affecting the precision of the data. The counts are made to obtain statewide vehicle-miles-traveled using statistics. As a result, individual counts may not represent an exact depiction of the traffic at a given site. Here are some facts about our data:
  • The traffic counts shown on the maps are AADT (Annual Average Daily Traffic) which are computed using factors.
  • Traffic is counted for 48 hours at most of the sites.
  • The 48 hour counts are adjusted to AADT using factors for day-of-week, season, and average percent trucks.
  • Approximately one third (1/3) of the traffic sites in a county or city are counted each year.
  • Traffic counts for previous 2 years are updated to the current year using factors based on traffic growth of counted sites statewide.
  • Some count locations are assigned to another location due to the similar traffic patterns and will share traffic count data.

We provide these traffic counts as a service and invite you to use them. However, we also caution you to understand that data may not be exact because of the methods used.
