Uses DfT STATS19 point data for 2019, aggregates into H3 hexagons (0.75 km²), normalizes counts and runs local Moran’s I spatial autocorrelation to map hotspots. Finds a dense central high‑high core, surprising outer high‑low pockets, an early‑morning crash peak, and fewer accidents on high‑precipitation days. Single‑year results fail to be explained by DfT attributes alone, so next steps bring in demographics and infrastructure (collaboration with CARTO) to test causal drivers.
