Summary

The United States must create a single, connected transportation system that is affordable, protects the environment, helps the nation compete globally, and moves people and goods using less energy. That system will link all kinds of travel, now and in the future, and include a National Highway System (including the Dwight D. Eisenhower System of Interstate and Defense Highways and key arterial roads needed for interstate and regional commerce, defense, intermodal transfers, and border crossings). It must also make major improvements in public transit to improve air quality, save energy, boost international competitiveness, and help older adults, people with disabilities, and low‑income people in cities and rural areas get around. The system must improve access to ports and airports and focus on productivity and social benefits like less pollution and congestion. The system must be run with attention to innovation, competition, energy efficiency, growth, and accountability, and avoid the costly practices of past highway projects. New technologies (for example, intelligent vehicles and magnetic levitation) should be used when practical and economical, with safety and cost‑benefit in mind. When appropriate, funding can come from the Highway Trust Fund, and federal help can assist states and localities. The Secretary of Transportation must give every Department employee a copy of this policy and post it in all DOT offices.

(a)It is the policy of the United States Government to develop a National Intermodal Transportation System that is economically efficient and environmentally sound, provides the foundation for the United States to compete in the global economy, and will move individuals and property in an energy efficient way.
(b)(1)The National Intermodal Transportation System shall consist of all forms of transportation in a unified, interconnected manner, including the transportation systems of the future, to reduce energy consumption and air pollution while promoting economic development and supporting the United States’ preeminent position in international commerce.
(2)The National Intermodal Transportation System shall include a National Highway System consisting of the Dwight D. Eisenhower System of Interstate and Defense Highways and those principal arterial roads that are essential for interstate and regional commerce and travel, national defense, intermodal transfer facilities, and international commerce and border crossings.
(3)The National Intermodal Transportation System shall include significant improvements in public transportation necessary to achieve national goals for improved air quality, energy conservation, international competitiveness, and mobility for elderly individuals, individuals with disabilities, and economically disadvantaged individuals in urban and rural areas of the United States.
(4)The National Intermodal Transportation System shall provide improved access to ports and airports, the Nation’s link to commerce.
(5)The National Intermodal Transportation System shall give special emphasis to the contributions of the transportation sectors to increased productivity growth.

(6)The National Intermodal Transportation System must be operated and maintained with insistent attention to the concepts of innovation, competition, energy efficiency, productivity, growth, and accountability. Practices that resulted in the lengthy and overly costly construction of the Dwight D. Eisenhower System of Interstate and Defense Highways must be confronted and stopped.
(7)The National Intermodal Transportation System shall be adapted to “intelligent vehicles”, “magnetic levitation systems”, and other new technologies, wherever feasible and economical, with benefit cost estimates given special emphasis on safety considerations and techniques for cost allocation.
(8)When appropriate, the National Intermodal Transportation System will be financed, as regards Government apportionments and reimbursements, by the Highway Trust Fund. Financial assistance will be provided to State and local governments and their instrumentalities to help carry out national goals related to mobility for elderly individuals, individuals with disabilities, and economically disadvantaged individuals.
(9)The National Intermodal Transportation System must be the centerpiece of a national investment commitment to create the new wealth of the United States for the 21st century.
