Roundabouts across the state are significantly improving traffic safety, according to an analysis of 18 years of crash data by Pennsylvania Department of Transportation.
The study of 11 roundabouts showed serious injuries dropping seven to zero and minor injuries dropping from 19 to one at the intersections that were previously stop or signal controlled. The total number of crashes dropped nearly 50 percent, from 101 to 54…
Fatalities like injuries and crashes, declined after intersections were converted to roundabouts as well. Prior to being conversion, a total of two fatalities had occurred at the locations considered in the study. No fatalities occurred at those locations after the conversions, according to PennDOT.
“Our data shows that modern-day roundabouts reduce crash severity and injuries while improving traffic flow,” said PennDOT Secretary Leslie S. Richards. “This underscores why roundabouts are becoming more commonplace in Pennsylvania and beyond.”
