ODOT OR 217 Active Traffic Management System
Reduced travel times by 7% and improved travel time reliability.
Quick Facts

Results
Since this economically responsible ATMS was implemented, average travel times have been reduced by 7% and travel time reliability has improved by 50% while traffic volumes have increased by 9%; public opinion has also been positive
ATMS components include:
Advisory speed signs that change based on current traffic and weather conditions
Traveler information signs that alert drivers to crashes, congestion, road conditions, closures and other traffic-related information
Travel time signs that display estimated travel times to key destinations
An adaptive ramp metering system that adjusts rates based on traffic conditions
A queue warning system that warns drivers of stopped or slowed vehicles ahead
