That sounds a little like the Barcelona superblock model, which I like. Less transit oriented and more "creating spaces for people to stay/live/eat/etc" oriented though.
Wow that is a fantastic idea that I would love to come to the States. Walking around in the city I always felt like this [0]. I have been really pushing for a car-free downtown on Sundays, its amazing how "human" you feel when you can walk around and interact without the drone and smell of traffic being a constant presence.
I live in Barcelona and while I personally love the Superilles, many of the locals who live near/in them hate them. They all say it's a huge inconvenience. That said, as a Canadian coming from one of the most car-centric cities in Canada (Calgary), anything that focuses on not driving is refreshingly wonderful.
