How bad is Toronto's traffic really?

I keep hearing that Toroonto has some of the worst traffic congestion in the world, certainly in North America. This seems to be due to a traffic survey by navigation company Tom Tom, which shows Toronto at third worst after only London and Dublin, and much worse than American cities like New York, which only ranks 20th in Tom Tom's analysis.

Well, I can believe it, from my own personal experience of driving around in recent years.

However, Inrix's Global Traffic Scorecard seems to tell a very different story. According to Inrix, a traffic data analysis and management company, Toronto's traffic ranks 17th worst, which is still not great, but significantly better than American cities like New York, Los Angeles, Boston, Miami and Philadelphia. It also shows Toronto's traffic on a gradual improvement curve over the last few years, which seems kind of hard to believe.

So, what are we to believe? Maybe it doesn't really matter. Ther point is, we shouldn't even be in the bottom 50!
