Seoul is employing AI-based technology as a novel way to prevent suicides.

The South Korean capital's bridges along the Han River are known for being suicide hotspots, with around 500 people attempting to kill themselves each year, according to the $4.

Seoul's new system involves a network of video cameras programmed to detect behavior typical of those who may be considering a suicide attempt, the outlet reported.

Through machine learning, these cameras zero in on people lingering too long on the bridge while corroborating their findings other surveillance recordings from the area. The system will then send signals to rescue teams stationed near the bridges. This is so dispatchers have a head start to deploy rescue boats and personnel quickly, either to try to stop the suicide attempt from happening or to rescue the person.

The technology was developed over the last year and a half by the Seoul Metropolitan Fire and Disaster Headquarters, in collaboration with the Seoul Institute of Technology.

"The most important thing in rescuing people who are trying to commit suicide is that they must be stopped before they're in the water. Once that happens, the survival rate drops below 50%," a spokesperson from the Seoul Metropolitan Fire and Disaster Headquarters told the Korea Times.

"We monitor 572 CCTV cameras in the control center, so it is not easy for a handful of workers to catch everything. But now the AI system selects footage of a person showing suspicious behavior and sounds an alarm so that rescue teams can respond much faster," he continued.

Local news site $4 reported that the cameras are linked to a control center staffed by officials around the clock.

The Korea Times noted that of the 28 bridges that line the Han River, those known to be hotspots for suicide attempts have had various suicide-prevention measures installed. This includes a pressure sensor on the Mapo Bridge that detects a person gripping the guardrails harder than usual and sensors on the Seogang Bridge that alert rescuers to bodies that fall beneath it.

Additionally, an $4 to make it more difficult for people to jump over its sides.

South Korea has consistently $4 in 2020, the country recorded $4 Suicide is the leading cause of death among young people in the country, and has been since 2007, per reporting from $4.
