Compound curve in highway

WebA compound curve consists of two or more simple curves having different radii bending in the same direction and lying on the same side of the common tangent. Their centres lie on the same side of the curve. In fig. 11.2, T 1 P T 2 is the compound curve with T 1 O 1 and PO 2 as its radii. (iii) Reverse (or Serpentine) Curve: ...
