From the Abstract: "Transportation is the 'web of union', and sustainability of systems relies upon political will. Sustainable transportation is the result of intentional policy at the strategic level and potentiates unified governance and economic growth. This paper proposes that a long term vision and four key principles of sustainable transportation are critical to success in establishing and operating transportation systems. Sustainable transportation is integral to U.S security and prosperity, and a critical component in strategy for peace keeping and stability operations abroad. Sustainable transportation is both foundational to and interdependent with security and prosperity. Peace and stability are reliant upon sustainable transportation that can best be accomplished in a comprehensive approach starting with a long term vision and focused on balancing the key sustainability principles of transportation resilience, economic development, environmental health, and social values."
