Note: This table categorizes some of the technologies and processes discussed in this chapter according to type of attack and type of R&D response. Also included, to show how they fit into the matrix concept, are two studies discussed in Chapter 2 (a compendium of lessons learned from past natural disasters and accidents and a study of redundancies and interdependencies). This is not a complete or exclusive list, just some examples arranged to illustrate the matrix approach.

  • 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 develop a better 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

The strategy begins with definition of the problem and establishment of objectives. As discussed in Chapter 3, DOT's broad objectives for R&D efforts in surface transportation security should resemble the following:
