Are Roundabouts Safer?
Quick answer: Roundabouts can reduce the number and severity of some vehicle conflict types because traffic moves in one direction around the central island and typically enters at lower speeds. Whether a roundabout is appropriate depends on the location and design.
What does intersection-safety research report?
Intersection-safety research generally finds that converting suitable conventional intersections to modern roundabouts can reduce severe crashes. Outcomes depend on geometry, approach speeds, pedestrian and cycling design, traffic volumes, and driver behavior.
Is this a blanket Sam Sinjari commitment?
No. Sam Sinjari’s platform supports improved intersections and road safety. This page explains one available intersection treatment rather than promising a roundabout at a particular location.
Research basis: Ewing & Dumbaugh (2009) and cited intersection-safety research.
