Paul Krugman has a couple of columns on the relationship between cost of transportation and its impact on urban growth and also international trade.
I have seen the future, and it works.

If Europe’s example is any guide, here are the two secrets of coping with expensive oil: own fuel-efficient cars, and don’t drive them too much.

Any serious reduction in American driving will require more than this — it will mean changing how and where many of us live.
To see what I’m talking about, consider where I am at the moment: in a pleasant, middle-class neighborhood consisting mainly of four- or five-story apartment buildings, with easy access to public transit and plenty of local shopping.
It’s the kind of neighborhood in which people don’t have to drive a lot, but it’s also a kind of neighborhood that barely exists in America, even in big metropolitan areas. Greater Atlanta has roughly the same population as Greater Berlin — but Berlin is a city of trains, buses and bikes, while Atlanta is a city of cars, cars and cars.
And in the face of rising oil prices, which have left many Americans stranded in suburbia — utterly dependent on their cars, yet having a hard time affording gas — it’s starting to look as if Berlin had the better idea.
Changing the geography of American metropolitan areas will be hard. For one thing, houses last a lot longer than cars. Long after today’s S.U.V.’s have become antique collectors’ items, millions of people will still be living in subdivisions built when gas was $1.50 or less a gallon.
Infrastructure is another problem. Public transit, in particular, faces a chicken-and-egg problem: it’s hard to justify transit systems unless there’s sufficient population density, yet it’s hard to persuade people to live in denser neighborhoods unless they come with the advantage of transit access.
And there are, as always in America, the issues of race and class. Despite the gentrification that has taken place in some inner cities, and the plunge in national crime rates to levels not seen in decades, it will be hard to shake the longstanding American association of higher-density living with poverty and personal danger.
Still, if we’re heading for a prolonged era of scarce, expensive oil, Americans will face increasingly strong incentives to start living like Europeans — maybe not today, and maybe not tomorrow, but soon, and for the rest of our lives.
