Math model may decrease phantom traffic jams
Method could help engineers design roads to keep traffic density low

Some traffic jams have no apparent cause — no accident, no stalled vehicle, no lanes closed for construction...
Great article and I'm glad scientists are studying these things as when I lived in the Atlanta metro area--thankfully in the Bay Area I rarely have to drive--it would be so frustrating when I figured out that a slow-down that could have you completely stopping at points was just about a lot of cars being on the road and nothing else.
Here's one more quote introducing a cool word:
Key to the new study is the realization that the mathematics of such jams, which the researchers call "jamitons," are strikingly similar to the equations that describe detonation waves produced by explosion...
That's what I'm calling them from now on as that is just a cool word: jamitons
