TRB's National Cooperative Highway Research Program (NCHRP) Report 525, Vol. 15: Costing Asset Protection: An All-Hazards Guide for Transportation Agencies (CAPTA) is designed as a planning tool for top-down estimation of both capital and operating budget implications of measures intended to reduce risks to locally acceptable levels. CAPTA supports mainstreaming an integrated, high-level, all-hazards, national incident management system-responsive, multimodal, consequence-driven risk management process into transportation agency programs and activities.

The guide is supplemented online with a downloadable Microsoft PowerPoint slide show and CAPTool, a spreadsheet tool for implementing the CAPTA methodology. A help file is also available online.

NCHRP Report 525: Surface Transportation Security is a series in which relevant information is assembled into single, concise volumesâ€"each pertaining to a specific security problem and closely related issues. The volumes focus on the concerns that transportation agencies are addressing when developing programs in response to the terrorist attacks of September 11, 2001, and the anthrax attacks that followed. Future volumes of the report will be issued as they are completed.
