alternativeTriggerThresholdMeters

Distance threshold in metres that separates the "monitoring" phase (far closure, informational banner) from the "find an alternative" phase (close closure, alternative route proposal).

Closures detected beyond this distance trigger a RouteClosureMonitoringNotification. Closures detected at or within this distance trigger a RouteClosureAlternativeNotification when an alternative route becomes available.

Default is DEFAULT_ALTERNATIVE_TRIGGER_THRESHOLD_METERS (250 km).
