| 摘要： | This eleventh volume of NCHRP Report 525: Surface Transportation Security will assist transportation, security, and emergency-preparedness planners as they identify and prioritize potential high-value transportation choke points (TCPs) such as bridges, tunnels, and passes. These high-value TCPs are located predominantly along major transportation routes. A key area of concern is how disruptive events will affect the flow of commercial traffic through TCPs. The Disruption Impact Estimating Tool-Transportation (DIETT) is an electronic analytical tool that calculates direct transportation and economic impact (costs) of an event that precludes the use of a TCP, and it prioritizes TCPs on the basis of these criteria. DIETT does not calculate replacement costs. Using DIETTs, prioritized sets of outputs, along with other risk information, decision makers will be able to better focus their capital resource, security, and emergency-preparedness planning. |
