Abstract
This paper analyzes the state of critical transportation infrastructure in the US, its relationship to security, and how the lack of an updated national policy to resolve the serious weaknesses of the transportation infrastructure negatively impact security. The difficulties in safeguarding transportation networks are identified along with the degree to which changes enacted since 9/11 regarding intelligence and administration, notably the establishment of the Department of Homeland Security, have led to increased security. However, these efforts, however successful, must be supplemented by a decision-making approach that goes beyond prevention and recognizes the importance of resiliency and such subsidiary concepts as robustness and redundancy.
