This study is part of a five-year (2012-2017) program to develop and promote technologies and methods to help urban transit systems restore service rapidly in the event of a biological agent attack. These experiments will build on previous subway airflow studies conducted in Washington DC, Boston and New York City. This program is sponsored by the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) and Office of Health Affairs (OHA).
