This study will explore opportunities for technology to address national needs for transportation security. While the primary role of the committee is to respond to the government's requests for assessments in particular applications, the committee may offer advice on specific matters as required. The committee will (1) identify potential applications for technology in transportation security with a focus on likely threats; (2) evaluate technology approaches to threat detection, effect mitigation, and consequence management; and (3) assess the need for research, development, and deployment to enable implementation of new security technologies. These tasks will be done in the context of current, near-term, and long-term requirements.The committee will perform the following specific tasks:--Identify potential applications for technology in transportation security with a focus on likely threats derived from threat analyses that drive security system requirements. Review security system developments structured to meet the changing threat environment. Assess government and commercial industry plans designed to address these threats.--Evaluate technology approaches to threat detection, effect mitigation, and consequence management. Delineate the benefits of the insertion of new technologies into existing security systems. Evaluate the trade-offs between effectiveness and cost, including the cost of changing the security system architectures. --Assess the need for research, development, and deployment to enable implementation of new security technologies. Review and assess the potential benefit of existing and advanced detection technologies, including scanning technologies, sensing technologies, and the use of computer modeling and databases. Review and assess emerging approaches to effect mitigation and consequence management.This project is sponsored by the Transportation Security Administration. The approximate start date for the project is October 15, 2002.Up to two topical reports per year are anticipated to be issued over the duration of the project. Additional reports may be issued as needed. Note: (10/11/2005) The project duration has been extended through August 2006, by which time additional reports are expected to be issued.
