The constant and efficient movement of people and goods
across the U.S. and around the globe is critical to the
economy and our lives. Today, our vital transportation infrastructure
is showing signs of aging, and we are experiencing
unprecedented congestion in our nation’s highways and railways,
at our airports, and at our seaports. Overcoming these
challenges will increasingly rest on the development and
deployment of new technologies and cutting-edge solutions.

We spoke with Paul Brubaker, administrator at the Research
and Innovative Technology Administration (RITA) within the
U.S. Department of Transportation, about his department’s
efforts in forging a transportation system for the 21st century.
