The Ohio Department of Transportation has released the results of a survey of crash data at 76 intersections around the state that had been converted to roundabouts.
The data shows single-lane roundabouts reduced injury-accidents by 69%. Multi-lane roundabouts reduced accidents by 25%.
The agency cites the Clark County intersection of State Routes 41 and 235 as one of the best examples.
Over the years, multiple safety upgrades were made to address a long history of serious crashes there with varying degrees of success.
Fatal crashes went up at one point, and it wasn’t until 2014, when a roundabout was installed, that injury crashes were reduced.
In fact, no fatal crashes have been reported in the 11 years since the roundabout was installed, and only a single serious injury crash occur
