• Description:
  A 2010 study for ODOT by researchers at the Oregon State University School of Civil and Construction Engineering titled, Evaluating Safety and Operations of High-Speed Signalized Intersections, examined effective means for improving safety at isolated, high-speed, signalized intersections with posted speed limits of 45 mph or greater and at least one approach isolated by one mile or greater distance. The study created a guide for roadway designers seeking incremental measures that can enhance intersection safety. These measures include improved advanced signing, extended amber or all-red clearance intervals, modified decision zones based on alternative reaction times, enhanced signal visibility, and other technologies that can further increase safe vehicle operations at these locations.
