The 2026 Notting Hill Carnival demonstrated how technology-enabled crowd management is reshaping public safety at major global events. Faced with attendance exceeding two million people and increasing concerns about crowd density, organisers and the Metropolitan Police Service adopted an integrated security model combining extensive CCTV coverage, live monitoring, drone surveillance, and predictive analytics to improve situational awareness and reduce the risk of crowd crushes and violent incidents. Advanced AI-powered video analytics enabled real-time monitoring of pedestrian flow, congestion hotspots, and behavioural anomalies, allowing control centres to deploy stewards and emergency responders proactively before conditions escalated. Predictive crowd modelling, supported by historical movement data and transport patterns, was also used to forecast pressure points across parade routes and transport hubs, improving barrier placement and traffic redirection strategies. The deployment of live facial recognition technology and drone-based aerial surveillance further enhanced operational intelligence. Overall, the Notting Hill Carnival case highlighted how modern urban events are increasingly relying on technology-driven intelligence systems to strengthen public safety, improve emergency response, and build resilience in complex, high-density environments.
