Seoul's Han River Bridges Implement AI Monitoring to Identify Suicide Attempts
Multiple Han River bridges in Seoul have deployed AI cameras to identify suicide attempts.
The system combines surveillance footage, thermal sensing, and rescue record training, focusing on reducing false alarms and issuing early warnings to rescue teams.
This investment is part of an event-driven public safety upgrade, benefiting the fire and rescue system while putting pressure on privacy concerns and existing management models for high-risk bridges.
South Korea has long ranked among the highest in suicide rates among OECD member countries, with approximately 500 suicide or attempted suicide incidents occurring on Han River bridges each year, prompting the use of AI as a preemptive interception tool.

Seoul's monitoring of Han River bridges is not a temporary response but a continuation of an earlier bridge protection system. Since 2013, Seoul has deployed surveillance systems on bridges, and after 2020, integrated cameras, thermal sensing, and rescue records into training, indicating that public safety strategies have evolved from "detecting anomalies" to "predicting risks." The path for capital and resources is clear: prioritize limited fire and rescue resources towards high-frequency risk points. The system's goal is not to replace human intervention but to filter out false alarms with models, shorten response times, and allow rescue teams to focus on segments where incidents are more likely to occur, which is a typical approach of "redistributing emergency capabilities using data." Similar cases have appeared in Japan, the UK, and some cities in the US, but the uniqueness of the Han River lies in its role as a city landmark, transportation infrastructure, and high-frequency risk scenario. In other words, this is not just an upgrade of ordinary security cameras but an integration of "infrastructure governance" directly into the psychological crisis intervention chain. Structurally, this is a technological substitution, where the replacement is not of people but of inefficient human monitoring patrols. The real change is in the method of risk identification: shifting from post-incident rescue to pre-incident warning, from dispersed patrolling to model screening, and from general coverage to high-probability interception.
