Thanks for that link - besides potential mass transit solutions, waves are all I think about when stuck in traffic. One thing to note, though, the linked page is wrong on the point that outflow can't be changed from a jam - if everyone in the jam accelerated as quickly as possible with almost no lag between each other, the entire jam point could move and eventually disperse. This would probably take coordination from networked robot drivers to pull off, though :-) since one slow driver could ruin the whole thing.
