PennDOT: Roundabouts reducing crashes, fatalities

Crashes, injuries and fatalities in the commonwealth decreased at four midstate intersection where roundabouts have been installed, according to data collected by the Pennsylvania Department of Transportation.

PennDOT reviewed three years of data for 11 roundabouts at intersections where traffic was previously controlled by stop signs or signals. The local intersections are in Cumberland, Dauphin and York counties

Department data based on police-submitted crash reports spanning the years 2000 through 2017 showed that fatalities and serious injuries were reduced by 100 percent and the number of crashes dropped 47 percent.

"This underscores why roundabouts are becoming more commonplace in Pennsylvania and beyond," Leslie S. Richards, PennDOT secretary, said in a statement.

In addition to the 11 roundabouts meeting the review criteria, 32 other roundabouts have been installed on state routes and 26 are in the design phase.

The Central Pennsylvania roundabouts included in the review are:

• The intersection of Spring Road (Route 34) and Sunnyside Drive (Route 1007) and Mountain Road at Sterretts Gap, Middlesex Township and Carroll Township, Cumberland and Perry counties, installed in 2014

• The intersection of Linglestown Road (Route 39) and Mountain Road (Route 3019), in Linglestown, Dauphin County, installed in 2011

• The intersection of Main Street (Route 16), Hanover Street (Route 3072) and Roths Church Road (Route 3059), in Spring Grove, York County, installed in 2007

• The intersection of Delta Road (Route 0074), Bryansville Road (Route 851) and Broad Street (Route 2015), in Delta, York County, installed in 2008.

Roundabouts are frequently installed to address intersections with safety issues, but may also be installed to improve traffic flow as well as for other reasons, such as traffic calming, and to facilitate pedestrian mobility, PennDOT said in a press release.

Although roundabouts are safer and typically more efficient than traditional signalized intersections, in many cases they may not be the best option due to topography or other reasons, such as property impacts, capacity issues and proximity to other intersections, the agency added.
