I think I've now got the hang of this: more intuitively, the traffic network can instead be modelled by an AC electrical circuit. The fluid dynamical aspects of flow along a single road might perhaps be incorporated by combining both models into a hydraulic analogue computer. Next time you're stuck in a traffic jam, try figuring out whether it's a UTM. Or would be, when/if ever it got moving again ... WFL On 5/22/15, Fred Lunnon <fred.lunnon@gmail.com> wrote:
The "standing wave" phenomenon in heavy traffic mentioned in the article is straightforward application of fluid dynamics, which I had ample opportunity to analyse during a particularly excruciating expedition along the London orbital motoway years ago.
I had to view the video in full-screen mode before I could follow it; now I understand the mechanical paradox, which still surprises me. But I don't see how the mechanical model maps to a traffic situation.
