Roundabouts in general are more efficient and safer. As with anything new, there is a short learning curve.
Roundabouts are nothing new at all. Where I grew up in North Jersey, we had them on one particular road since the 50s or 60s, but they were called circles. At one point, some time in the 80s, they did away eith them as they were too dangerous. Funny to see them make a comeback.

I live near, and drive through, roundabouts, a Divergent Diamond,and a SPUI (Single Point Urban Interchange
traffic moves far quicker and safer through all of these than standard stop lights with left turn arrows.

The design and operation of the old traffic circles was drastically different and cause major issue.
- Modern roundabouts are designed to limit speed thru them. Old traffic circles often could be taken at high speeds.
- Modern roundabouts yield on entry. Many traffic circles were so large they included yield within the circle.
They really are a different animal.

Excellent! Whoo-Hoo
Hold your horses.......7 round-a-bouts are being built also.
Had to do something with the monies being allocated.
Maybe they have enough dirt to bury the moron next to use here at the Thousand Trails blm spot who runs his open frame generator from 6:30 AM until midnight.

Show me an intersection design that works well when the driver is going thru a heart attack. :S
Reality is roundabouts used in appropriate places are great. Even if you are unfamiliar because of the low speeds, they tend to have fewer crashes and the crashes you do get tend to be minor fender benders.
People get nervous because they are different. Reality is they are very simple to drive:
- Single Lane Roundabouts: Look to your left on approaching. If you have a gap, go. Otherwise wait for a gap. Once in, proceed until you reach your exit.
- Multi Lane Roundabout: Approach in the same lane as if it was a normal intersection (ie: if you are turning left, enter in the left lane). Otherwise it's pretty much the same.
This was about 15yrs ago, the first big roundabout in Michigan and I was in the Traffic Department. We were all sure it was going to fail, so when they opened it and there was a web cam, we all gathered around to see the carnage. After about 15minutes, we were convinced it wasn't fully open as there were no backups, so we sat an intern down to count cars. A couple hours later we totaled up the numbers and it was carrying 5,000 cars per hour with no backups. I only know of 3 signalized intersections that come close to that volume of traffic and backups & delays are substantial at all 3.
This is not to say a poorly designed roundabout won't be a problem but the vast majority of complaints are people just not comfortable with something new.

They put a roundabout on a rural road out by me that is a heavily traveled North/South route. well they made it so tight that semis cannot negotiate it. and there was no need for it, because the intersection it was put in doesn't see that much side road traffic!
You should see the new ridiculous interchanges they now have for expressways with the lanes switching sides over the bridge. completely ridiculous!
