Pilot project uses AI to prevent suicide in Montreal Metro

Once indicators of distress are detected, trains can be signaled to slow down and someone could go up to the person in need and offer help, according to the Socit de transport de Montral.

The Socit de transport de Montral (STM) and researchers from the Center for Suicide Intervention (CRISE) are developing an artificial intelligence system as part of the public transit authority's suicide prevention strategy.

The pilot project scans closed circuit television, or CCTV, footage in the city's Metro stations to detect warning signs that a person may be in distress.

"We've analyzed the videos of all the people who attempted suicide [in the Metro]with the goal of trying to see if there are some indications that someone might be in distress," Brian Mishara, CRISE director and co-investigator of the STM AI project, told Daybreak Montreal host Sean Henry.

"We've got some indicators, but obviously a human cannot watch hundreds of screens all day long to try to identify those behaviors," said Mishara, who is also a professor of psychology at the Universit du Qubec Montral(UQAM).

Once those indicators are recognized by the AI system, measures can immediately be taken to try and save the person from hurting themself, he says, adding that the system does not use facial recognition software.

A pilot project is being developed that would use artificial intelligence to scan CCTV footage in the Metro to detect certain warning signs that an individual may be in distress. Daybreak host Sean Henry spoke with Brian Mishara, the director of the Center for Suicide Intervention, or CRISE, to learn more about how this technology would work.

In a statement, the STM told CBC that the system could warn the control room in real time, possibly the metro operators directly,allowing the trains to brake in advance andspecial constables tobe deployed to the scene.

"Someone could be sent to the station to go up to the person and say, are you OK? Do you need some help?"Mishara said.

At the moment, Misharasays that the AI can correctly recognize one out of four people who will attempt suicide.

Adding barriers to preventpeople from jumping off the platformis another idea, but it's an expensive solution, he says, especially as the STMseeks to cut costs to balance out its budget shortfall.

The STM described the AI pilot project to CBC as "promising" and said it hopes to implement the system in two years.

It also says that the goal to implement platform screen doors has been reinstated as part of its 2023-2033 plan with $5 million earmarked for studying the project.
