Rural Traffic Flow Map
This is a map showing rural traffic in Montana. Annual Average Daily Traffic (AADT) has been weighted based on established major traffic breaks. This map is intended to give users a general idea of the traffic flow in Montana's rural areas.

Total traffic volumes (Types 1-13) are represented using color bands with the weighted volumes being reported for each segment directly above the roadway segment. The volume being reported directly underneath the roadway segment is total commercial volume (Types 5-13).

Do not add total traffic volume and total commercial volume together. The total traffic volume already includes total commercial volume.
