Weba) The term “NC” (normal crown) represents an equal downward cross-slope, typically 2%, on each side of the axis of rotation. b) The minimum curve radii for normal crown are suitable up to 3.0%. c) 3.0% normal crown should only be used when 3 or more lanes are sloped in the same direction. WebFeb 23, 2012 · The major considerations in horizontal alignment design are: safety, grade, type of facility, design speed, topography and construction cost. In design, safety is always considered, either directly or indirectly. Topography controls both curve radius and design speed to a large extent. The design speed, in turn, controls sight distance, but sight
