> Sure if you also remove, people, bikes and everything else. To clarify, I'm talking about fluid-dynamic-like models of traffic congestion (oversimplification: traffic behaves like a compressible fluid). It's been a while since I studied this, but my impression is that synchronizing can eliminate some of these effects (perhaps make traffic more like a non-compressible fluid). So I wasn't implying that people and bikes and mechanical failures would never stop traffic, but rather that traffic can better respond to those obstacles, and flow rate can be improved.
