Roundabouts and J-turns improve safety and road user experiences. While public familiarity and acceptance of these alternative intersections designs increase over time, questions remain regarding economic impacts on nearby businesses. An analysis of roundabouts and J-turns continued to show benefits for road users and no notable negative economic impacts on nearby businesses.

New Project: Roundabouts, J-Turns, etc. – Understanding Their Economic Impacts
Roundabouts and J-turns have consistently shown significant improvements in safety and traffic flow in Minnesota and across the U.S. Still, some community residents and businesses oppose replacing traditional intersections with alternative intersections like roundabouts or J-turns.

The risk of severe crashes increases when minor roads intersect with higher-speed roads in rural areas. MnDOT and county traffic engineers strive to find creative solutions that will prompt drivers to make safe decisions when navigating through intersections.

MnDOT traffic engineers are increasingly installing J-turn intersections on high-speed, multilane expressways to limit potential crash points. An analysis of crash data from intersections before and after the installation of J-turns demonstrated significant safety benefits from this alternative design. MnDOT researchers also explored crash history differences among J-turn intersections with varying characteristics. Consistent with the results from a previous study, this analysis found a clear decrease in fatal and other serious crashes after a J-turn was installed.
