U.S. Department of Transportation Research, Development, and Technology Plan. Sixth Edition, FY2005

摘要

Americans depend on safe, efficient, and secure transportation systems. Whether we travel on roads, boats, rails, or in the air, we rely on our transportation systems to get us where we need to go. The same systems play a crucial role in our national economic well-being-making it possible to move goods from place to place and to succeed in the global marketplace. Transportation is also critical to our national defense and to providing security against terrorism. The Department of Transportation (DOT) works in tandem with owners and operators of our transportation systems to provide leadership and guidance on behalf of the public. DOT is responsible for the nation's freedom of movement-ensuring that there are sufficient and safe roads, rails, transit systems, airways, and seaways to keep the country in motion and its economy growing. As always, DOT's top priority is to guarantee the safety of the traveling public. Fostering the innovations that will improve transportation safety-while ensuring security, increasing capacity, and reducing environmental degradation-are the goals of DOT's Research, Development, and Technology (RD&T) program.
