Homer Watson and Ottawa Three Lane Roundabouts

[Owen]

I grew up in a country where roundabouts are common. In my experience they work best for low volume intersections and they quickly become a nightmare for busy ones. I've waited for over 5 minutes at rush hour when traveling westbound on Erb St at Ira Needles because northbound traffic on Ira Needles was relentless.

Often in the U.K., when traffic flow becomes bogged down in one or both directions because of high traffic volumes, you will see traffic signals added to the roundabouts ... 

And you thought we had it bad here in the Waterloo region....
