Abstract:This Final Report reviews a research effort to evaluate the safety and operations of high-speed intersections in the State of
Oregon. In particular, this research effort focuses on four-leg, signalized intersections with speed limits of 45 mph or
greater where the intersections are not in the immediate vicinity of other signalized intersections. This report includes a
literature review of high-speed intersection safety treatment strategies, a description of the research methodology used in
this project, and a summary of final results. The final results include crash conditions at these high-speed intersections, a
format for evaluating safety at these and similar intersections, a hierarchy of safety treatment options, and a demonstration
of the use of these tools through example analyses of eight Oregon intersections.
