WebbThe simple curve is consists of a single arc. The compound curve consists of two or more arcs with different radii. The reverse curve consists of two arcs that curve in different directions. And the spiral curve (or transition curve) has a varying radius, so that the curve starts out very flat and increases in sharpness as we move into the ...
