I have vague memories of a physics lecture I attended in college where the prof developed a wave equation for traffic jams. It was identical to compressing a spring with a mass, except the factors were "jumpiness," or propensity to tailgate the guy in front of you, and "fear" of slamming into his rear end. Thus your speed tends to sinusoidally oscillate. I leave it to you to develop the equations ("proof left to the reader as an exercise"). Dave Emberson Megatest Corp. Sunnyvale, CA megatest!dre
