  • The corridor’s 2010 crash rate was 0.66 crashes per million vehicle miles compared to the statewide average for urban freeways of 0.52 crashes per million vehicle miles

  • By 2025, the traffic volumes are expected to increase another 30%

  • 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

Our Work

  • Directed a team of nine subconsultants in the successful completion of final contract documents in just seven months from notice to proceed

  • Developed systems engineering documents and concept of operations and requirements

  • Prepared temporary traffic control plans to accommodate traffic during construction

  • Temporary traffic control stages included lane/shoulder closures, full freeway closures with detours, and ramp closures

The OR217 ATM PS&E package was delivered to Salem yesterday (1 day early!). I wanted to say thanks to you and your team … Your team was able to develop innovative solutions, make early contact with stakeholders, and keep a close eye on the project … Great job!
