Here is a really neat idea that I stumbled upon during my sustainable city research at work. They are prototype plans for a linear city…basically urban design based upon transit. At the top of this page is a line of red text. If you click on this it will give you a cool outline of the design idea.
The lack of cohesive mass alternative transportation in American cities is one of the largest challenges we face as we attempt to work towards sustainability. Correcting this flaw is far harder than if we had built our communities based on this idea from the get-go. There are tons of cool ideas out there but I found this one to be particularly well laid out for the average reader to go through. Check it out and see if you learn something.
