Description

TRB's National Cooperative Highway Research Program (NCHRP) Report 525: Surface Transportation Security and TRB's Transit Cooperative Research Program (TCRP) Report 86: Public Transportation Security series publications have jointly published Making Transportation in Tunnels Safe and Secure. The report is Volume 12 in each series. The report is designed to provide transportation tunnel owners and operators with guidelines for protecting their tunnels by minimizing the damage potential from extreme events such that, if damaged, they may be returned to full functionality in relatively short periods. The report examines safety and security guidelines for owners and operators of transportation tunnels to use in identifying principal vulnerabilities of tunnels to various hazards and threats. The report also explores potential physical countermeasures; potential operational countermeasures; and deployable, integrated systems for emergency-related command, control, communications, and information.

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.
