Susceptibility bands (modelled)
Suggest a correction
Spotted a wrong name, a map that looks wrong, an off fleet figure, a missing line, or a hotspot that does not squeal on the ground? Local knowledge beats the model. Corrections feed the next build.
Email a correctionModelled, not measured. Geometric squeal susceptibility before mitigation, computed from open OpenStreetMap centreline geometry; never a noise prediction and not validated against measured sound levels. Fleet figures from public sources.
Bring us your noisiest curve, or problem section.
Show us the curve that will not stop squealing and we will model it with you, then show you what conditioning the interface can do, or if other interventions are required.
