A city plan built on a grid of roundabouts for easy traffic flow and no stoplights [see link].

Lots of roundabouts for precisely that reason [imaginality, Mar 29 2007]

...ooo... nasty [jonthegeologist, Mar 30 2007]

what a horrible, horrible idea. The people I drive with like to go a bit fast, so all of us would be jammed up against each other and the windows. :)

//you'd have to go clockwise in some circles and counterclockwise in others! Me thinks there'd be accidents a-plenty.// Are you only able to make left turns?

no turns at all, only merges...

I would like the concept of planning a city based on islands of walking distance homes, shops and offices, surrounded by ring roads and peripheral parking lots. Then again, I think that's what we have in a number of cities.

The "Schematic Plan" looks to me like there would have to be a stoplight at every intersection.
-- BJS, Mar 29 2007


Bear left or bear right, every intersection is a merge.
-- nuclear hobo, Mar 29 2007


they're all "cross-over" merges too -- those suck. North Carolina, in the states, loves to put those where two highways intersect. You have people trying to merge onto the ramp while the people on the ramp are trying to merge off of it... bit of a cluster-something'r'other.

Nope. Google's satellite map of Milton Keynes shows A509 with a series of evenly spaced roundabouts. Roundabout City is a grid of roundabouts, with housing, commerce, education, etc. place in the large circles - these are circular city 'blocks' around which traffic flows.

I learned to drive in a (small) city with no traffic lights - the last pair having been replaced with a roundabout. There was a combination of roundabouts, give ways and through ways.

Boy there were some hairy moments when I moved to the big smoke.

Meanwhile, I get the logic of your plan.
