# United States Department of Transportation

The United States Department of Transportation (USDOT or DOT) is one of the executive departments of the U.S. federal government. It is headed by the secretary of transportation, who reports directly to the president of the United States and is a member of the president's Cabinet.
The department's fiscal year 2022–2026 strategic plan states that its mission is "to deliver the world's leading transportation system, serving the American people and economy through the safe, efficient, sustainable, and equitable movement of people and goods."

## History

In 1965, Najeeb Halaby, the chief of the independent Federal Aviation Agency strongly urged President Lyndon Johnson to set up a cabinet-level Department of Transportation. Halaby proposed merging the responsibilities of the undersecretary of commerce for transportation and the Federal Aviation Agency to achieve this goal. While the federal government was granted authority over aviation and railroads through the commerce clause of the Constitution, the Federal Highway Administration and Federal Transit Administration primarily provided funding for state and local projects, without significant influence over road construction and operation. Halaby emphasized the need for improved coordination and expressed frustration at the lack of an overall plan. "One looks in vain", he told Johnson, "for a point of responsibility below the President capable of taking an evenhanded, comprehensive, authoritarian approach to the development of transportation policies or even able to assure reasonable coordination and balance among the various transportation programs of the government." Johnson convinced Congress to act and The Department of Transportation was authorized in October 1966 and launched on 1 April 1967, with a mission to ensure that federal funds were effectively used to support the national transportation program. Johnson proclaimed upon signing the act: "Transportation has truly emerged as a significant part of our national life. As a basic force in our society, its progress must be accelerated so that the quality of our life can be improved."

## Budget

In 2012, the DOT awarded $742.5 million in funds from the American Recovery and Reinvestment Act to 11 transit projects. The awardees include light rail projects. Other projects include both a commuter rail extension and a subway project in New York City, and a bus rapid transit system in Springfield, Oregon. The funds subsidize a heavy rail project in northern Virginia, completing the Washington Metropolitan Area Transit Authority's Metro Silver Line to connect Washington, D.C., and the Washington Dulles International Airport (DOT had previously agreed to subsidize the Silver Line construction to Reston, Virginia).
President Barack Obama's budget request for 2010 also included $1.83 billion in funding for major transit projects. More than $600 million went towards ten new or expanding transit projects. The budget provided additional funding for all of the projects currently receiving Recovery Act funding, except for the bus rapid transit project. It also continued funding for another 18 transit projects that are either currently under construction or soon will be. Following the same, the Consolidated Appropriations Act of 2014 delegated $600 million for Infrastructure Investments, referred to as Discretionary Grants.
