Sorry. It's the engineer in me. Two lanes feeding into the single lane RB may or may not create a bottleneck. Again, it is a capacity thing. I think for about 90% of the time, a single lane RB would move traffic smoothly. In the winter, during rush hour, one may experience a backup...

OOOOO I love that!! It would be way less scarey than what we have now. (especially in season)

Of course it is a capacity issue. I believe it would have an impact much of the time.

Yep. Single lane is simply not viable.

At Hilton Head Island, a solution that has worked for many tears is requiring you to be in the right hand lane to exit a traffic circle. If you are in the right hand lane, you must exit the circle at the next fork. You cannot exit from the center lane. In other words, there is only one lane exiting a circle, though it can immediately expand to two lanes

These circles are probably too small for that. It would require about 2/3 of the cars to change lanes in the RBs.

There is nothing wrong with the roundabouts as they currently are. If people would look at the signs placed before entering each roundabout and follow the paths shown (remembering that a vehicle in the inside lane that entered the roundabout earlier can turn right), there would be no problem.

Yes. The signs are perfect. Basically, just remember that a car can use either lane to exit or continue around, depending on where it entered the RB. How simple. I wonder why there is so much confusion.

This is not true. According to the signs (on the roundabout near where I live anyway), for the first exit you should be in the right hand lane and not the left hand lane. If you are going straight through the roundabout, either lane is OK. If you are going 270 degrees around you should be in the left hand lane. It doesn't get much simpler than that.

That's from your perspective. The vehicle that got onto the RB from another street sees it differently, thus a car can exit, or not, from either lane. now, if you can keep track of everyone and where they entered, you're doing pretty good.

[biker1]

It doesn't really matter as a car in the RB has the right of way over cars trying to enter the RB. At the bottom of the RBs it goes down to one lane so a car in the RB already (and not exiting before it goes down to one lane) can then position into the correct lane for an exit (and they have the right of way over cars trying to enter). If I enter from my Villages and plan to exit immediately then I will be in the right hand lane. If I am going in the opposite direction (270 degrees) I can enter either lane as I know from the signs that either lane can go straight through. I don't see an issue. Works great for the vast majority of people. Those who have problems with the RBs will probably have problems with any form of intersection.

The easiest explanation I ever read was, think of a 4-way stop for two 2 lane roads intersecting. If you were making a right turn you would be in the right lane. If you were going straight, you could be in either lane. If you were turning left, you would be in the left lane. Same idea but convert it to a circle, now you have it.
