    "body_text": "Sungkyunkwan University researchers developed a computer-vision system intended to flag passengers at risk of being trapped by closing subway doors. The model uses one CCTV frame to classify risky boarding behavior and reported 97.58 percent accuracy in the study dataset, aiming to warn operators before an entrapment occurs. The result is a research evaluation, not evidence of performance across every station, camera angle, crowd, weather condition, or deployed transit network.",
