"Traffic circles" have gone and raised the ire of Winnipeggers again.
I've seen and used roundabouts in Europe, where they are an integral part of many traffic systems and actually work. The reason they don't do so well here is that most drivers do not know how to use them properly and the city and province have not done much to help the situation. The result is that they remain foreign and confusing and people will actually take time to go protest when new ones are being built.
It's too bad because, according to the US Federal Highway Administration, a country where many cities have been converting intersections to roundabouts for decades, they are a much safer alternative to other types of intersections. Their data shows that:
- By converting from a two-way stop control mechanism to a roundabout, a location can experience an 82 percent reduction in severe (injury/fatal) crashes and a 44 percent reduction in overall crashes.
- By converting from a signalized intersection to a roundabout, a location can experience a 78 percent reduction in severe (injury/fatal) crashes and a 48 percent reduction in overall crashes.
A huge part of what makes a roundabout work, and how cities around the world manage to make (gasp!) multi-lane roundabouts work, is that drivers must SIGNAL OUT of them. If not, some or all of the four approaching lanes of traffic must come to a stop when a car is inside the roundabout because you have no clue what it is going to do. It also makes it dangerous for cyclists sharing the roundabout if cars are going to suddenly pull out.
If you don't believe me about signaling out, check out the Manitoba Drivers Handbook, p. 52: "Continue until you reach the street you wish to exit, signaling your intentions to exit before you reach the street you wish to exit on to." MPI, on the Road Safety section of its website, sums it up this way: "When you are ready to exit the roundabout, you must signal your intentions and yield the right of way to pedestrians and cyclists."
By not signaling out, a roundabout becomes nothing more than an an expensive, poncy looking, rolling 4-way stop. Why bother even changing it over, then?

Since this has been a bugbear of mine since roundabouts were introduced on Waterfront Drive, I always keep an eye out for who signals out and, more importantly, who does not. I have been in the circles with transit buses, police cars and fire engines, all official vehicles that should be obeying the rules of the road. I have NEVER seen one of them signal out. EVER.
I remember when Brandon introduced a couple of large roundabouts to its west end a decade or more ago. Manitoba Public Insurance (MPI), I believe it was, had a series of temporary signs the side of the road as you approached with handy tips: "Remember: yield to the car on the left"; "Remember: you must signal out". It was a simple way to get people used to the rules.
I don't blame city planners for adding roundabouts. On paper, and in most jurisdictions, they actually work to keep traffic flowing, (and who wants to stop at a red light or 4-way stop when there is no oncoming traffic?) If crosswalk features are properly designed into them, assuming you live in a city where drivers actually stop at crosswalks, (which could a whole other blog post), they are safe and easy to use for pedestrians and cyclists as well.

So what can be done to get roundabouts back on track?
- Call them what the traffic act calls them: roundabouts, so people who are curious about the rules can actually search and find them.
- MPI needs to do a better job on their online education products. The roundabout section of the Manitoba Driver's Handbook is dismal and, as far as I can tell, you have to download the whole booklet to read that one section. The roundabout section I could find on MPI's website is just some text with a reminder that people should watch the 60 Second Driver bit on CTV, no hyperlink is provided.
- At roundabouts in the city, the city and MPI or the city should introduce temporary signage to introduce drivers to the rules, similar to what was done in Brandon.
- Civil servants using city vehicles, including police, fire and transit, need to set good examples for others on the road and follow the rules. This includes following the rules in roundabouts.
