PennDOT Data Shows Roundabouts Reduce Fatalities, Injuries, and Crashes

The state Department of Transportation has announced that fatalities, injuries, and crashes decreased overall at 26 roundabouts at 23 locations in the time since they were built.  

“The modern roundabout is simply safer than the traditional intersection,” says PennDOT Secretary Yassmin Gramian. “Though not the right option for every intersection, data shows that when installed, roundabouts save lives and reduce crash severity.” 

PennDOT recently reviewed data for 26 roundabouts on state routes at intersections that were previously stop- or signal-controlled. These roundabouts were selected based on having at least three years of crash data available before and after the roundabouts were built. Department data based on police-submitted crash reports spanning the years 2000 through 2020 shows that fatalities at these locations were reduced by 100%, and the total number of crashes decreased by 22%. In addition, suspected serious injuries were reduced by 81%, and suspected minor injuries were reduced by 36%. Click here to learn more.
