The Greater Yellowstone Rural Intelligent Transportation System (ITS) Priority Corridor (Corridor) extends from Bozeman, Montana to Idaho Falls, Idaho. The combination of varied, often less-than desirable driving conditions coupled with abundant off-road, commercial and recreational traffic, indicates an immediate and ever growing need for increased traffic safety and information measures. Intelligent Transportation Systems (ITS) is the strongest solution available and appears to be appropriate for the Greater Yellowstone Rural ITS Priority Corridor.
