An immutable class that defines triggering thresholds for different severities of speed alerts,
represented by GMSNavigationSpeedAlertSeverity.
You can use this to customize the speed alert triggering thresholds in percentage for both minor
and major alerts, and customize the time based triggering threshold for major speed alert.
The speed alerts triggered by corresponding thresholds from this GMSNavigationSpeedAlertOptions
have UI customized in GMSNavigationSpeedometerUIOptions if set.
The duration threshold controls the speed alert severity upgrade. A major speed alert is
triggered when the speed exceeds the minor speed alert threshold for more than the given number
of seconds.
Gets the speed alert threshold (as a percentage) for the specific
GMSNavigationSpeedAlertSeverity. A value of 0.0 represents 0%, and 1.0 represents 100%. A
negative value indicates no threshold being set for that speedingType.
