Going With the Flow of Traffic - WSJ
Mathematicians have studied traffic flow by means of a clever shift in perspective. Instead of regarding each car as an individual entity, we can treat traffic as a substance that is flowing like a fluid. This sort of abstract reframing is often useful for connecting one situation to another that is better understood—in this case, the rich field of fluid dynamics.

When studying a fluid, the basic variables are its density and flow rate. In the simplest case of water flowing smoothly through a pipe or traffic flowing smoothly on a highway, the density and the flow rate are constant. But obstacles, junctions and changes in the size of the pipe or highway disrupt the flow and have progressive knock-on effects. The density of traffic changes in response to these issues as drivers hit the brakes and bunch up in slow-moving traffic.
