This is an excellent thread, with lots of good information. But I have to correct the data on the U.S. Department of Transportation budget. The $275 billion is for the surface transportation program that is renewed every six years (or supposed to be). The $275 billion total is over six years.
Taking all modes into account, the federal amounts for each transportation mode in recent years have been:
Highways - $35 billion (funded heavily by gas taxes)
Aviation - $11 billion (funded heavily by airline ticket taxes etc)
Mass Transit - $5 billion (less than half funded by gas taxes)
Army Corps of Engineers (Ports/Waterways) - $4 billion (funded in part by waterway usage fees and the rest by general revenues)
Amtrak (Railroads) - $1 billion (funded entirely by general revenues; no ongoing federal trust fund or user fee has been enacted by Congress for rail unlike all of the other modes)
Here's the federal funding history for three of those surface transportation modes presented in graph form:

Here's another bit of interesting information, though it's getting a bit dated (they have done some updates since). I don't agree with everything they say, but there is some useful information in here...

STUDY RELEASED BY THE INTERNATIONAL CENTER FOR TECHNOLOGY ASSESSMENT (CTA) DETAILS OVER $1.69 TRILLION IN SOCIAL COSTS AND GOVERNMENT 'WELFARE' FOR GAS INDUSTRY
MIDDLE EAST TENSIONS AND GLOBAL WARMING MAJOR CONTRIBUTORS TO MASSIVE INCREASE IN THE REAL COST OF GAS
Washington D.C. -- A report released today by the International Center for Technology Assessment (CTA) calculates that the actual cost of a gallon of gas to the American consumer could be as high as $15.14. The report "The Real Price of Gas" identifies and quantifies the many external costs of using gas that consumers pay indirectly by way of taxes, insurance costs and retail prices in other sectors. Established in 1994, the International Center for Technology Assessment (CTA), is a Washington-based research organization that analyzes how technology affects society.
The CTA study examines more than 40 separate cost factors associated with gasoline production and consumption. These include subsidies for the petroleum industry such as the percentage depletion allowance; tax-funded programs that directly subsidize oil production and consumption, like government-sponsored R&D for the oil industry; the costs of protecting oil supplies, shipments and motor vehicle usage, including military expenditures for protecting the Middle East and other oil rich regions; and environmental, health and social costs including those for global warming. Together these subsidies for gas paid by consumers total up to $1.68 trillion per year.
The Report will be released at a news conference today, Tuesday, November 17, 1998, at 10 a.m. The conference will be held at the offices of the Communications Consortium at 1200 New York Avenue, N.W. (AAAS Building, 1 block from Metro Center), Second Floor, Revelle Conference Room. Scheduled panelists include Andrew Kimbrell, and Joseph Mendelson of CTA, Ann Mesnikoff of the Sierra Club and Gawain Kripke of Friends of the Earth.
According to CTA Director Andrew Kimbrell, "The real price of gas has been hidden from the consumer for far too long. Some of these costs including those associated with military actions in the Middle East and global warming could skyrocket in the coming years. Once the public understands how much they are really paying for gas we should see a tremendous increase in political pressure for alternatives."
Joseph Mendelson III, CTA legal director commented, "This Report has major policy implications. For example, the Environmental Protection Agency (EPA) is currently drafting standards for the next generation of automobiles through the "Tier II" process. This Report indicates that the EPA should encourage a significant move away from gas-powered vehicles."
