Funny what apparently simple differences in mathematical models can imply. I studied an old-school "Wardrop model" of traffic flow in one class in school. In that model, your speed along a road segment is a function of the flow (vehicles per hour), and it's usually assumed to be monotonic (or at least non-decreasing.) In the article, the images never show increased throughput coinciding with longer travel times. In the Wardrop model, equilibrium traffic levels are unique, and in TFA's model they aren't. (The diagrams make this clear in a really nice way, I like them a lot.) I wonder whether/when each model is a better description of reality. It's hard to imagine the road in that Office Space clip demonstrating especially veh/hr flow...
