New Urbanism

There is a website dedicated to the idea of a new kind of urbanism. From the site:

Giving people many choices for living in more sustainable, convenient and comfortable places, while providing the solutions to global warming, climate change, and peak oil

NewUrbanism.org was started in 1998, and has since grown to become a leading and well respected informational website promoting walkable urbanism, transit oriented development, trains and sustainability.
