Roundabouts save lives and keep motorists safe.
That’s according to data from a 2022 PennDOT study that indicates fatalities, injuries, and crashes have decreased overall after intersections at 39 locations across the state were replaced with 42 roundabouts.
PennDOT data for 36 single-lane and six multi-lane roundabouts on state routes at intersections that were previously stop or signal controlled. This update to data released in 2022 now includes an additional seven roundabouts.
The roundabout on Glen Eden Road, Powell Road, and Freshcorn Road was included in the study. It was installed in 2015 and has been routinely included in PenDOT safety studies.
Department data from 2003 through 2022 obtained from police-submitted crash reports and weighted based on the number of before and after years, but not for increases in traffic volume shows that crashes involving suspected serious injuries were reduced by 24%; crashes involving suspected non-serious injuries were reduced by 51%; and the total number of crashes were reduced by 3%.
