EYEWITNESS NEWS (WBRE/WYOU) — PennDOT announced Monday that their departmental data shows an overall decrease in deaths, injuries, and crashes after 33 intersections were replaced with 36 roundabouts.
According to PennDOT, recently reviewed data for 36 roundabouts at different intersections that were previously stop signs or traffic lights. The roundabouts were chosen based on having at least 3 years of crash data available before and after the roundabouts were built.
The data from 2002 through 2021, based on police-submitted crash reports show the following:
- Suspected serious injuries were reduced by 76 percent.
- Suspected minor injuries were reduced by 22 percent.
- Possible or unknown severity of injuries was reduced by 70 percent.
- The total number of crashes decreased by 9 percent.
PennDOT stated, that there was one death in one of the roundabouts, however, prior to the roundabouts being built, there were a total of 3 fatalities, so the numbers are still decreasing.
