Manto

10.0

Qualità mediana del manto. Asfalto liscio = 10. Chipseal = 8. Ghiaia = 5.

Tortuosità

0.0

Tortuosità mediana. Punteggi più alti significano più curve per chilometro.

Velocità

4.0

Adeguatezza del limite di velocità. Punto ideale a 60-110 km/h.

Classe stradaSecondary road

8.0

Classificazione stradale. Le autostrade hanno zero. Le strade terziarie hanno 9.

Dislivello

5.5

Variazione di altitudine per chilometro. Più salita = punteggio più alto.

Road intel

Grey spots10 of 8 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.

Storico incidenti

Aggregato su 8 tratti

Zone grigie

Il collegamento dei registri incidenti non è ancora disponibile per WA. Le zone grigie sono tratti dove la geometria di curvatura non corrisponde al limite di velocità - vengono segnalate indipendentemente dallo storico incidenti.
