This podcast from Transport Security International Magazine focuses on the increasing threat of terrorist attacks on surface transportation, such as buses, trains and cars. The podcast explores the challenges of securing such a vast and open network, particularly compared to airport security. It discusses the Department of Homeland Security’s (DHS) efforts to develop new technologies for screening potential threats, including a layered, curb-to-platform detection system that could automatically highlight possible threat items. Experts are interviewed who debate the trade-offs between security and privacy, particularly regarding the use of advanced surveillance technologies. The podcast also highlights the importance of public vigilance and training in preventing terrorist attacks.
