Methodology: Zone rankings are based on incident frequency and cable infrastructure data only — not demographic or socioeconomic factors. Risk score = 50% normalized incident frequency + 50% normalized cable length at risk.
Human Decision Required
The AI recommends a deployment order based on risk scoring. Municipal operators must decide which zones to prioritize based on operational, political, and community factors the model cannot assess.
