The Department of Transportation's proposed budget for the 2010 fiscal year includes $800 million toward a next-generation air traffic control system. "The 2010 budget supports moving from a ground-based radar surveillance system to a more accurate satellite-based surveillance system, development of more efficient routes through the airspace and improvements in aviation weather information," the DOT says.

Also, the budget includes a five-year, $5 billion state grant program for high-speed rail, a proposal that the DOT says "marks President Obama's commitment to provide Americans a practical and environmentally sustainable alternative to flying or driving."
