This podcast from Transport Security International Magazine advocates for the use of crowdsourced threat detection in transportation security. It argues that utilising a mobile app for reporting suspicious behaviour can improve situational awareness and make transportation venues safer by enabling travellers and employees to quickly and discreetly report potential threats. The podcast highlights the limitations of traditional 9-1-1 calls and the increasing preference for text-based communication. It also suggests that using an app to regularly report suspicious activity can encourage a proactive approach to security, creating a “muscle memory” for reporting. The podcast further addresses the importance of protecting the safety of both employees and travellers who report incidents, and emphasises the need for a simple and user-friendly interface to facilitate effective reporting. It concludes that crowd-sourced reporting has the potential to significantly enhance proactive security measures and mitigate potential hazards in transportation environments.
