Grey spots7 of 38 segments

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

Wet riskModerate

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.

Crash history

Aggregated across all 38 segments· 5 years of data

Grey spots

Crash record linkage not yet available for WA. Grey spots are segments where curvature geometry mismatches the posted speed limit - these are flagged regardless of crash history.
