Volumes listed by Highway Number and Mile Post
This section contains a tabulation of ODOT Highway Numbers listing Annual Average Daily Traffic, or AADT, at various milepoints along the highways. This includes all vehicle totals in both directions, unless identified as one-way traffic.
Approximately one third of State Highways are counted each year and adjusted to a current AADT. The AADTs for the remaining two thirds of the State Highways are adjusted to reflect area traffic growth trends.
When a new highway is completed and opens to traffic for only part of the year, the AADT as given in this tabulation is presented as if the facility was open to traffic for the entire year.
An asterisk appearing to the left of a count location description indicates an Automatic Traffic Recorder Station or Automatic Vehicle Classification Station. More in-depth information is available for these permanent sites, such as monthly traffic volumes or historical trends.
