  When a highway is close to capacity, it only needs to be blocked for a short period of time for it to back up traffic for miles. So if there's a rush from a particular suburb, it could very well cause traffic problems at a specific time. No traffic is more natural, per se, than any other traffic. Again you've repeated the claim that you can single out users and attribute, essentially, blame. This study is most certainly bunk. Someone thought it would be novel to try the sort of traffic analysis that every single traffic department in the world does, and of course they're going to try to discern some profound finding, like "lots of people come from lots of people to hit the city core at 8:30am".

    > Again you've repeated the claim that you can single out users and attribute, essentially, blame. Where did I claim that? You seem to be missing something, somewhere. The gist of the article is that large bunches/waves/schools of traffic travel in from outlying suburbs. I imagine that where that pack travels, jams ensue, and anything that you can do to smooth out that peak will help traffic flow more smoothly. And they're using cell phone signals/GPS to track drivers down to the individual level. Pretty sure not many traffic departments do that sort of analysis, even if you type it in italics. Mostly it's just pressure sensors to measure average flow of particular roads.
