What cities have the best traffic?

Apparently, bad traffic is a common problem in US cities. Who’da thunk it? I’m in Seattle, and although we’re not on that Forbes list, we’ve sometimes shown up on “country’s worst traffic” lists.

What cities never show up on those lists? What cities have minimal congestion, reasonable commute times, few delays, and overall excellent – or even good – traffic management?

It’d be even more interesting to know what makes their traffic flow so smoothly. Bonus points for explanation.

And yes, I’d love to hear about non-US cities that handle their traffic well.

There’s no such thing as bad publicity, and there’s no such thing as good traffic.
