More traffic circles are being built across South Carolina and statistics from the state’s Department of Transportation reveal they have reduced the number of accidents and injuries at intersections where built.
The Independent Mail of Anderson reports that 15 traffic circles have been installed across the state. Five more are under construction and an additional 20 are in the design phase.
Numbers from the SCDOT show traffic circles resulted in a 74 percent reduction in total crashes, a 68 percent reduction in crashes with injuries and a 100 percent reduction in the number of deadly accidents compared to the traditional intersections they replaced.
Program Director Chris Jordan told the newspaper that he believes the drop-off is because roundabouts eliminate left-hand turns at intersections and, with them, the possibility that cars will be hit broadside. He also believes the traffic flow means those accidents that do happen in a traffic circle are less likely to cause serious injury.
He said roundabouts also cost less money to maintain than traffic signals once built.
