It provides a transition from the tangent to a simple curve or between simple curves in a compound curve (Figure 3-2, View D). 1.2.0 Elements of a Horizontal Curve The elements of a circular curve are shown in Figure 3-3

(3) A lemniscate, the first two are used on railways and highways both, while the third on highways only. When the transition curves are introduced at each end of the main circular curve, the combination thus obtained is known as combined.

Surveying may be defined as the science of determining the position, in three dimensions, of natural and man-made features on or beneath the surface of the Earth. These features may then be represented in analog form as a contoured map, plan or chart, or in digital form as a three dimensional mathematical model stored in the computer 3.
