Comparing America's transportation menu to that of Western Europe, this article details some of the reasons behind various deficiencies in U.S. transportation.
"The Congressional Budget Office estimates that America needs to spend $20 billion more a year just to maintain its infrastructure at the present, inadequate, levels. Up to $80 billion a year in additional spending could be spent on projects which would show positive economic returns. Other reports go further. In 2005 Congress established the National Surface Transportation Policy and Revenue Study Commission. In 2008 the commission reckoned that America needed at least $255 billion per year in transport spending over the next half-century to keep the system in good repair and make the needed upgrades. Current spending falls 60% short of that amount.
If Washington is spending less than it should, falling tax revenues are partly to blame. Revenue from taxes on petrol and diesel flow into trust funds that are the primary source of federal money for roads and mass transit. That flow has diminished to a drip. America's petrol tax is low by international standards, and has not gone up since 1993 (see chart 3). While the real value of the tax has eroded, the cost of building and maintaining infrastructure has gone up. As a result, the highway trust fund no longer supports even current spending. Congress has repeatedly been forced to top up the trust fund, with $30 billion since 2008."
