TRB's National Cooperative Highway Research Program (NCHRP) has released a request for proposals to develop a recommended second edition of Security 101 for transportation personnel without a security background whose work requires them to address, perform, or supervise security or infrastructure protection activities as a part of their overall job responsibilities. The updated Security 101 should be suitable for adoption by the American Association of State Highway and Transportation Officials (AASHTO) Special Committee on Transportation Security and Emergency Management (SCOTSEM). Proposals are due September 22, 2015.
