Public transit operates in inherently open environments. It provides ease of access and gathers volumes of people in confined spaces to provide passengers with efficient and convenient transportation. These unique attributes make public transportation vulnerable to adversarial targeting and threats. For these reasons, a sound understanding of anti-vehicle barriers will enable agencies to implement an approach to more effectively manage the risks of their environments. This document describes AVBs for transit passenger facilities, providing information on their specific uses, capabilities and placement considerations.
