Remarks

Only valid for sag curve. This design method for sag curves provides a minimum curve length. The curve must be long enough so that in dark driving conditions, the headlights of a standard vehicle illuminate the road a safe distance beyond the stopping distance for the designed speed of travel.

Exceptions

Exception	Condition
System.ArgumentException	Thrown when the input parameter is out of range (negative, unable to resolve etc).
System.InvalidOperationException	Thrown when CurveType property is Crest.
