I have always liked roundabouts, they seem to allow traffic to flow a little faster, and you're not stuck waiting at an unnecessary red light in the middle of the night struggling with the temptation to drive through it.
Roundabouts are far more common in the U.K., but lately I have seen a few being built in and around the Toronto area. Here in the Quinte region, Picton has two of them. They are quick and easy once people get used to them.
Initially they will cause a bit of confusion to the uninitiated who might be a little hesitant when they first encounter one, but really there's nothing to worry about. Just look to the left, and if the coast is clear, just go go go. Remember to exit on the correct road though, otherwise you'll have to turn around and do it all over again.
The road around Trenton's new roundabout isn't paved yet, but that didn't stop me from test driving around it a couple of times when noone else was looking. It's a great solution to a very awkward intersection which formerly had a three way stop servicing four directions. This intersection had more than its fair share of confusion in the past, and I think that the new roundabout might prevent some accidents in the coming years.
I suspect that this is the beginning of a trend in Ontario, and soon we will be seeing more and more of these being built. They make a lot of sense.
