This report on the environmental impacts of transportation in the US should make interesting reading at some point in the future, when I have time…. =)
Along with a report which “proves” that Most mis-estimates of transportation expenditures are lies, not errors.
Also, several from the Victoria Transport Policy Research Institute, including: Understanding Smart Growth Savings, Evaluating Research Quality, evaluating transportation land use impacts.

Neat! But it’s in alpha. =)
