Grey spots8 of 9 segments

Segments where curvature is tighter than the posted speed limit. Geometry alone flags these as higher risk, no crash history required.

Wet riskElevated

Average wet sensitivity across segments, based on surface, drainage, gradient and local rainfall.

Night riskPresent

Visibility at night across the road, weighted by lighting, tree canopy density and curves.

Wind exposureModerate

Average wind exposure across segments, based on measured wind speed, terrain and shelter. Relevant for motorcycles and caravans.

Sun glarePresent

East-west segments exposed to sunrise and sunset glare, adjusted for tree cover.
