How to design a city?

these benefits are quantified when building a road see NATA. what is not quantified well is the dis benefits of road building e.g they screw a city up through noise, generally not being pleasant..etc. and not really moving that many people that efficiently.

OK, so our city will have no roads.
Where will the buildings be?
How will the materials to build them be delivered?
How will the people who build them get there?
How will the people that live, work or shop in them get there?
How will the goods that are sold in shops get there?
How will people get those goods home?

Can't be by bike, because there are no roads. Can't be by train because trains are noisy, inefficient and unpleasant and those are your reasons for eliminating roads. Can't be by canal or helicopter for the same reasons. Which brings me to my last question,

Who the fuck would want to live there?

glad you are so assertive on the matter. enjoy yelling at people in your car becuase they are ALWAYS FULL in urban areas.

Inference fail. That was my appraisal of Greenpeace's attitude, not a precis of my own.
Oh and by the way, I don't drive. I suggest you use something other than your blind prejudices to inform your opinions.
