The architectural principle of Southern NH is that streets are not organized in a grid but rather in a hierarchy. They add more suburban "pods" at the leaf nodes with resulting uncontrollable traffic increases at upper levels.
A street grid scales in an entirely different way in that if you build more grid you add both short- and long-range access at the same time.
A town I live near added "traffic calming" measures, in some cases draconian. (e.g. When the cop catches you turning towards the supermarket when you shouldn't be you tell him that you're entirely confused by the streets in the area, you blow 0.0, and he says he is confused by it too.)
As soon as traffic calming went into place, traffic got much worse on nearby arteries, particularly wait times at street lights.
My current theory is that a good traffic route avoids stop lights like the plague. It's inevitable that you will hit stop lights, wasting your time and fuel. If you go to places where traffic concentrates, traffic will eventually outflow the ability of cars to clear the intersection during the green cycle. So a single traffic light causes you to be stuck for several cycles.
If you think for yourself you realize that you can clear 10 stop sign intersections in the time that you can clear a bad pair of lights.
I don't apologize for any of this behavior because I am making life better for people in the herd by getting out of it.
