@MeteredPotatoCorp, I am glad you liked it and learned something from it. I was just experimenting how to solve traffic problems and ended up with this kind method.

I learned quite a bit from looking at this. My current city is 1/10 the size, but has a much, much larger percentage of people using mass transit. And I still have traffic problems. Obviously your people are walking to work. The biggest lesson I learned was to mix up zone types a little more and maybe to avoid having huge industrial areas. We have a much different playing style and I wouldn't ever want to build a city like this one, but I was still able to take something away from it. Thanks for sharing.
