Economists are generally one-trick ponies on the subject of urban transportation: get the prices right (with congestion taxes) and let the market decide.

Yonah Freemark is not an economist. But he’s a Yale-bred architect who knows a ton about urban transportation and writes prolifically about it. Check out his blog, The TransportPolitic, for a nuanced view of the subject.
