Use CCTV analytics/AI to detect at-risk behaviour (loitering at platform ends, letting trains pass, trackside intrusion) and alert staff in real time — technically promising but without empirical evidence of reducing suicides in practice.

Use camera surveys (handheld, vehicle- or drone-mounted) with machine-vision models to automatically detect, count and classify litter over large areas — producing objective, repeatable density data to target action and rigorously measure whether interventions worked.

Ellipsis Earth deployed camera-based machine-vision surveys to provide objective before/after litter density and composition data for Hubbub's Ballot Bin and Big Ballot Bin interventions in the UK, serving as the measur…
