                Reasons for Drivers Failing To Yield at Multi-Lane Roundabout Exits: Transportation Pooled Fund Study Final Report

              Abstract:This document discusses how roundabouts represent an important intersection control strategy for the Federal Highway Administration (FHWA) due to their ability to drastically reduce severe crashes. They are listed as one of FHWA’s Proven Safety Countermeasures. Since FHWA published its first roundabout informational guide in 2000, the estimated number of roundabouts in the United States has grown from fewer than a hundred to several thousand.



As roundabouts become more common across a wide range of traffic conditions, roundabouts with more than one lane are seeing increased use. These multi-lane roundabouts have demonstrated good safety performance with respect to crashes involving injuries or fatalities, but some multi-lane roundabouts have experienced higher-than-desired property damage only (PDO) crashes, especially at exits. This final report details the work performed for a Transportation Pooled Fund (TPF) project that investigates root causes and contributing factors for PDO crashes near multi-lane roundabout exits. The findings presented here provide guidance to practitioners and public agencies in support of proactive reductions in the potential for crashes at new multi-lane roundabouts and possible countermeasures to reduce PDO crashes at existing sites.
