I think the roundabout is a better alternative to improving traffic flow than traffic lights. The problem I have been experiencing is that people, are inexperienced in using them. In particular, I have most often noticed elderly drivers appear confused that there are "yeild" signs and not "stop" signs. Congestion is compounded by drivers stopping and/or hesitating even when there isn't any traffic concerns. Recently, I attempted to make a right turn from Hamlin West onto Livernois North and was prevented by another driver who just stopped at the intersection and waited excessively for the roundabout to clear of all traffic. The driver then made the same turn to go northbound on Livernois. This driver clearly had a clear path and the right-of-way, but seemed confused or afraid to proceed after yeilding, and treated the signal as if it was a "stop".

Round-abouts are prevelent in many parts of Europe and have been best solutions for improving congestion at various intersections.

If drivers use appropriate speeds and caution, there is seldom any reason for the majority of traffic to come to a complete stop and therefore moves traffic more efficiently than traffic lights.
