MDOT Traffic Counts

   To start using  the map application below to display the traffic counts, you can either start zooming into the area of interest or use the Google search box to locate a  city, county, or address. The traffic counts will start appearing once you start zooming in closer. Select the year of traffic data from the Year pull down selection box. The  traffic counts are displayed within color coded boxes. A Blue Box indicates that the count was not counted within that year and the AADT was estimated as mentioned  in the additional information below the traffic map application. A Red Box indicates that the count was counted in the year and the AADT is based on that count. The latest 10 year historical traffic count table can also be  displayed by clicking on the count box which follows the same color scheme. Information regarding traffic data collection is available below the traffic map application. For additional information, you may call the Planning Division at 601-359-7685 and ask for the  Traffic Analysis Section.

   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
  • Traffic is counted for 48 hours at most of the sites.
  • 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 a factor based on traffic growth of counted sites statewide.
  • The traffic counts shown on the maps are AADT (Annual Average Daily Traffic) which are computed using factors.
  • The 48 hour counts are adjusted to AADT using factors for day-of-week, season, and average percent trucks.
  • Factors are derived from Continuous Traffic Recorders (CTR) located across the state on all types of roads.
  • Some count locations are assigned to another location due to the similar traffic patterns and will share traffic count data.
  • CTRs count full time through out the year using special detectors, which some classify vehicles into the 13 FHWA Vehicle Classification System including passenger vehicles and trucks.
   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.
