Safety and Security
Risk is inherent in travel. In recent decades society has become increasingly adept at managing traditional risks from collisions, fires, and mechanica
l failures. A steady stream of requirements and products designed to protect people while traveling has resulted in remarkable safety gains across all modes. Design standards for vehicles and infrastructure, consumer products, and regulations governing use of the system are constantly being improved, all of which involve complex technical analyses and consideration of costs and benefits. The nation often turns to The National Academies for expert guidance in these areas, and the Transportation Research Board (TRB) has convened many committees to lend their insights and wisdom.
The tragic events of September 11, 2001, and subsequent terrorist strikes against innocent travelers in Madrid and London have brought home the urgent need to protect against a different kind of risk—terrorism. Society is much less skillful, however, at integrating such protection into the operations of the transportation system while also accounting for cost and convenience. Unfortunately, the risk of terrorism shows no signs of abating any time soon. TRB committees are being increasingly called upon to assist in this area also.
