Cool! I'm curious about the traffic patterns -- for example I see them slow down towards areas of complexity and speed up on straights. Is this just an emergent property of the number of control points on your traffic curves, or was it intentional? It would be cool if some kind of max-flow algorithm were applied to generate realistic traffic flow speeds; a kind of baseline throughout measurement for the road system geometry without further detail.
