Book Description
This report overviews the strategic implications of the Highly Reusable Space Transportation (HRST) program. The analysis postulates the anticipated HRST market (window is 2006-30, with a 2015 focus). Next the analysis speculates on market 'price of entry' for several potential markets. HRST is envisioned as a NASA overlay to either the STS modernization or the on-going RLV initiative. Three NASA options are reviewed. An example HRST program (MagLifter + RBCC RLV) is assessed in terms of financial/political issues. The merits of HRST-vs-RLV are briefly examined. Finally, a Small Launch Vehicle (SLV) HRST application is reviewed. Duffey, Jack and Lowrey, Alan Marshall Space Flight Center NAS8-39209...

Book Description
RAND evaluated a terrorism risk modeling tool developed by the Transportation Security Administration and Boeing to help guide program planning for aviation security. This tool, the Risk Management Analysis Tool, or RMAT, is used by TSA to estimate the terrorism risk-reduction benefits attributable to new and existing security programs, technologies, and procedures. RMAT simulates terrorist behavior and success in attacking vulnerabilities in the domestic commercial air transportation system, drawing on estimates of terrorist resources, capabilities, preferences, decision processes, intelligence collection, and operational planning. It describes how the layers of security protecting the air transportation system are likely to perform when confronted by more than 60 types of attacks, drawing on detailed blast and other physical modeling to understand the damage produced by different weapons and attacks, and calculating expected loss of life and the direct and indirect economic consequences of that damage. This report describes RAND's conclusions about the validity of RMAT for TSA's intended uses and its recommendations for how TSA should perform cost-benefit analyses of its security programs.

Book Description
The transportation system is the backbone of any social and economic system, and is also a very complex system in which users, transport means, technologies, services, and infrastructures have to cooperate with each other to achieve common and unique goals.The aim of this book is to present a general overview on some of the main challenges that transportation planners and decision makers are faced with. The book addresses different topics that range from user's behavior to travel demand simulation, from supply chain to the railway infrastructure capacity, from traffic safety issues to Life Cycle Assessment, and to strategies to make the transportation system more sustainable.

Book Description
"The U.S. transportation system, comprised of aviation, freight rail, highway, maritime, mass transit and passenger rail, and pipelines, moves billions of passengers and millions of tons of goods each year. Disrupted terrorist attacks involving rail and air cargo in 2010 demonstrate the importance of effective information sharing with transportation security stakeholders. The Transportation Security Administration (TSA) is the lead agency responsible for communicating security-related information with all modes. In response to the Implementing Recommendations of the 9/11 Commission Act of 2007, GAO assessed 1) the satisfaction of transportation stakeholders with the quality of TSA's transportation security information products, 2) satisfaction with mechanisms used to disseminate them, and 3) the extent to which TSA's roles and responsibilities are clearly defined. GAO surveyed 335 aviation, rail, and highway stakeholders (with an 82 percent response rate); reviewed agency planning documents; and interviewed industry associations, transportation stakeholders, and Department of Homeland Security officials. An electronic supplement to this report-GAO-12-67SP-provides survey results. "

Book Description
This report describes many ways in which science and engineering can contribute to making the nation safer against the threat of catastrophic terrorism. The report identifies key actions that can be undertaken now, based on knowledge and technologies in hand, and, equally important, describes key opportunities for reducing current and future risks through longer-term research and development activities.
