• Abstract:
  The primary goal of this study was to assess how rural roundabouts in Kansas impact roadway safety. The study utilized comparison groups and a before-and after study as well as a thorough benefit-cost analysis to determine the return on investment for roundabouts in rural areas. This research also aimed to assess crash frequency at rural roundabouts in Kansas and compare it with crash frequencies at conventional stop-controlled or signalized junctions in surrounding rural areas, thereby evaluating the overall safety performance of rural roundabouts.
