• Abstract:
  This report documents the research effort to quantify the safety performance of roundabouts in the State of Oregon. ; The primary goal of this research is to provide the Oregon Department of Transportation (ODOT) with safety ; performance functions (SPFs) that can be used to evaluate the safety performance of single-lane, four-leg ; roundabouts. These safety metrics generally conform to the statistical models and methodologies similar to those ; outlined in the Highway Safety Manual (HSM) published in 2010 by the American Association of State Highway and ; Transportation Officials (AASHTO).
