AI Cameras Significantly Enhance Bridge Rescue Rates in Seoul

AI-powered cameras implemented on Seoul's Han River bridges have dramatically improved rescue rates for individuals experiencing suicidal ideation. Since the system's deployment in 2021, the success rate for interventions on these bridges has surged to over 99 percent, a substantial increase from the previous 56 percent recorded in 2012. This technological advancement allows for rapid detection and response, significantly increasing the chances of saving lives.
AI System Identifies Individuals in Distress

The artificial intelligence surveillance system is designed to detect specific behaviours indicative of potential suicide attempts. It monitors individuals who linger in designated areas on bridges, those who enter zones deemed unsafe, or anyone interacting with the dedicated suicide-prevention phones installed on the structures. This multi-faceted approach enables the system to identify a range of at-risk behaviours.
Rapid Response Within Critical Time Window

A key factor in the system's effectiveness is its ability to facilitate swift interventions. Emergency crews are dispatched and can reach most of the Han River bridges within a crucial five-minute window. This rapid response capability is vital, as it provides the opportunity to engage with individuals during the critical period when intervention is most likely to succeed.
Substantial Increase in Incidents Identified and Rescued

In 2024, the AI surveillance system, which comprises nearly 900 cameras across 17 bridges, was instrumental in identifying over 1,200 incidents. While the vast majority of these situations resulted in successful rescues, approximately eight individuals could not be saved last year, highlighting the ongoing challenges despite the system's advanced capabilities.
