MnDOT makes the case for modern roundabouts

Think you know traffic circles? Think again. In this 11-minute video, MnDOT makes the case for the modern roundabout: not only are they safer than traditional four way intersections with traffic lights, they're more efficient too. The video also includes some helpful tips on how to navigate the circles.

Round abouts only

make sense within dense population areas. They do not make sense out on a highway where a much less-used State or County road, for instance, intersects. The highway traffic should not have to slow down for the occasional side-road vehicle.
A prime example of this questionable decision-making is on heavily-traveled U.S. Highway # 2 five miles out of Ashland, Wisc......the only highway between the U.P. and Duluth.

U.S. # 2 is intersected by Wisc. St. Hwy # 13....the one which goes to Bayfield. Other than during Bayfield's annual 3-day 'apple festival', traffic on # 13 is very limited compared to U.S. # 2.
However, all U.S. # 2 traffic must now slow down to a crawl in order to navigate the circle...at all times. In this situation, an overpass for State # 13 would have made much more sense...and probably not cost any more $.
However, it appears that the WDT got caught up in a fad and whomever their DOT head is, he/she bit hard on the bait.

Rather old and biased toward 1-lane roundabouts

This video is 7 years old! Still, they do seem to like roundabouts.

I like them well enough in some situations, but only the 1-lane versions. All the safety advantages the video mentioned were about the 1-lane versions. multi-lane roundabouts have more crashes than traditional intersections, though generally less severe.

For bicycles 1-lane roundabouts work just fine and safety stats suggest they are at least as good as traditional intersections. Bikes in multi-lane roundabouts have a much worse time of it.
