Securing Surface Transportation
Surface transportation such as subway systems can be a unique security challenge due to the large crowds of travelers and the open, unstructured environment. Public safety officials (including mass transit operators, mass transit police, and state and federal law enforcement teams) need a capability to detect potential threat items on persons and in bags without negatively impacting the speed of travel. S&T is developing technology to meet this challenge with the Surface Transportation Explosive Threat Detection Program, helping provide a layered, integrated capability to detect and mitigate the explosive threat at the speed of the traveling public.
