Snapshot: Security at the Speed of Life

DHS S&T is developing a millimeter wave imager that will screen for potential threat items unobtrusively as people pass by, without slowing them down.  

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.

Snapshot: A Simple Solution to Protect Critical Infrastructure

The Department of Homeland Security Science and Technology Directorate (S&T) has a solution to protect subway systems from threats in the form of a giant inflatable plug that will seal off subway tunnels and stop water from flowing throughout the subway system into stations and other subway lines.

S&Ts Unique Video Forensic Tools Implemented by Mass Transit Authorities

It’s actually not movie magic that facilitates saving the day; it is a technologically advanced reality being demonstrated right now thanks to tools in development by the Department of Homeland Security Science and Technology Directorate. The technology is being tested within the Washington Metropolitan Area Transit Authority (WMATA) by the Metro Transit Police to ensure riders’ safety.

DHS S&T to Conduct Airflow Study in NYC Subway

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) will conduct a week-long airflow study in portions of the New York City (NYC) subway system to gather data on the behavior of airborne particles in the event contaminants were released. This study poses no risk to the general public and will run from May 9 to May 13.

DHS, MBTA to Begin Series of Tests for Rapid Biological Response Sensors

August 27, 2012 —The Department of Homeland Security (DHS) is working with the Massachusetts Bay Transportation Authority (MBTA) to test a system of newly developed biological detection sensors at MBTA stations in Cambridge and Somerville this summer. The effort, to detect and minimize any impacts from an attack or accident involving hazardous biological materials in a mass transportation system, is being coordinated with the Massachusetts Department of Public Health, the Cambridge Public Health Department, and the Somerville Health Department, with support from the Massachusetts Emergency Management Agency.

Surface Transportation Program

The Surface Transportation Explosive Threat Detection Program’s goal is to provide the surface transportation end-user community with a layered and integrated capability to safely detect potential threat items in unstructured crowds, while maintaining individual privacy.
