The Bangkok Metropolitan Police Bureau said the National Research Council of Thailand sponsored the project which launched in March last year.
The first AI-linked equipment has been installed on Rama VIII Bridge in Bang Phlat district, Bangkok, reports the Bangkok Post.
Pol Maj Gen Pitak Uthaitham said Rama VIII Bridge was chosen for the pilot project because data showed it was the most popular for people with sucidal tendencies.
He said the AI monitors activity on the bridge and would send an alarm to police when it detected people whose behaviour suggested they were thinking of jumping into the river. Police would then rush to the scene and hopefully stop them.
If they were too late, the system could still locate the person in the river and direct rescuers to the scene to save them.
Pre-suicidal behaviour included people pacing back and forth, standing stock still, and trying to clamber over the guard rail.
The project could be expanded to other bridges nationwide popular for suicides, Pol Maj Gen Pitak said.
The Metropolitan Police Bureau organised a meeting on the pilot project at a hotel in Bangkok on Friday (Mar 27). While they were busy talking, two bodies were found under Rama VIII Bridge.
