And yet, I believe it is true that it is impossible to solve traffic problems by building more roads. Better access to a given area inevitably increases the rate of growth in that area, and before you know it you're right back where you started. Plus, in many cases, addition more capacity is just not feasible. I do support building more and better roads (not toll roads, ideally), but it does seem to to be a losing battle.
My commute route has several traffic lights that are so out of time, it makes the trips impossible.
