• further assessment of threat likelihood, where possible
  • a more complete, balanced, and clearly defined analysis of possible means of attack
  • more attention to cyber attacks and other attacks on C3 systems, especially attacks other than the introduction of computer viruses
  • a close examination of chemical and biological vulnerabilities
  • careful distinction between chemical attacks and biological attacks and between attacks involving agents with different properties
  • an examination of strategic, systemic vulnerabilities

To improve its understanding of strategic vulnerabilities, DOT should undertake (1) a strategic assessment of the surface transportation system's redundancies and interdependencies, and (2) an analysis of lessons learned about impact and mitigation from past accidents and natural disasters.

When DOT conducts a complete and thorough evaluation of potential R&D topics, using this systematic five-step strategy, the following themes will emerge:

  • the value of taking a dual-use approach, in which security objectives are furthered at the same time as other transportation goals
  • the potential for more use of modeling to improve understanding of the scope of the security problem
  • the importance of DOT's role in developing and disseminating information about best practices that use existing technologies and processes, including low-technology alternatives
  • the need to consider security as part of a broader picture, not a wholly new and different problem, but one that is similar and closely connected to the transportation community's previous experience in responding to concerns about safety, natural disasters, and hazardous materials
