Two roundabouts in Delaware County are reducing roadway fatalities, writes Mat Bennet for patch.com.

PennDOT included them among 33 across the state that is having an impact.

Singled out in Delaware County were the circles at Route 1023/North Newtown Street and Route 1046/St. Davids Road in Newtown Square, and the circle at Route 320/Chester Road, Rutgers Avenue, and Fieldhouse Lane in Swarthmore.

New data shows a reduction in fatalities, injuries, and crashes at the 33 different intersections across the state after roundabouts replaced them.

“While they aren’t the right option in every intersection, we’re pleased that they help to make our roadways safer,” PennDOT Secretary Yassmin Gramian said in a statement.

PennDOT reviewed data for 36 roundabouts installed over the years throughout the commonwealth, all placed in areas previously controlled by traditional traffic signals or stop signs.

The chosen intersections had at least three years of crash data available before and after the roundabouts were installed.

Besides the 36 roundabouts highlighted in its report, PennDOT said another 38 have been built at other locations, 16 are under construction and 15 are in the final design stage.
