The mission of the Journal of Transportation Security is to disseminate new research, thought, and analysis for teachers, researchers, policy makers and practitioners who view transportation security as a critical element of our world.   Since the inception of transportation networks, security has always played a role in planning and execution, albeit a tertiary one to increased efficiencies and reduced costs. Over the past two decades, however, ongoing attacks by criminals and terrorists have altered the ways that transportation security is viewed by governments and industry. Protecting the physical infrastructure of transport systems along with cargo, passengers, and personnel is now held as both a national security priority and an organizational necessity. Fundamental to fulfilling the mission of JTRS is a global, multi-disciplinary approach to the subject of transportation security.   Over the past ten years, at least ten articles have been published from each of these varied areas of specialization: legal studies; supply chain management; engineering and technology; maritime and ocean transport; economics and business; emergency management; criminology; rail and mass transit; aviation security; geopolitics; public policy; education and knowledge management; cybersecurity and space; and road and inland transport.Officially cited as: J Transp Secur
