PennDOT data shows roundabouts improving safety, reducing crashes

Posted: Updated:

The Pennsylvania Department of Transportation says the use of roundabouts helps to not only reduce crashes and injuries but also improve traffic flow.

PennDOT announced Thursday that according to department data, crashes, injuries, and fatalities decreased at 11 roundabouts after they were installed.

The roundabouts reviewed were previously stop or signal controlled and were reviewed based on having at least three years of data available before and after the roundabout's installation. 

Department data based on police-submitted crash reports between the years 2000 to 2017 shows fatalities were reduced by 100 percent, serious injuries were reduced by 100 percent, minor injuries were reduced by 95 percent, possible/unknown severity injuries were reduced by 92 percent, crashes causing only property damage fell by two percent and the total number of crashes dropped 47 percent.

Thirty-two other roundabouts have been installed on state routes and 26 are in design.  PennDOT also plans to build a roundabout at the intersection of Route 62 and State Street in Hermitage.
