I agree that the junction tag could be given a value for those circular 
traffics that are not a roundabout. However it needs to be a positive 
tag describing the situation, and a negative what it is not. Otherwise 
the robotic minds of some mappers will attach the "not-a-roundabout" to 
every other junction!

Thus junction=circular_traffic or junction=traffic_circle would work for 
me. It would be helpful to get the American English perspective 
beforehand, to avoid using something too much a synonym to roundabout.

Oxford: "traffic circle ; N-Amer; a road junction at which traffic moves 
in one direction around a central island."
Does this imply any priority regulation??

those are good as well, and avoid AmE/BrE conflicts. "circular" is nice 
and concise.
