An ideal transition curve is
IRC recommends Spiral or clothoid as the ideal transition curve due to following reasons:
1. It satisfies that rate of change of centrifugal acceleration is constant i.e., Ls.R = constant. Where Ls = length of transition curve R = radius of curve.
2. The calculation and field implementation of spiral curve is simple and easy.
3. It enhances aesthetics also.
Pantagraph is used for
If the angular measurements of a traverse are more precise than its linear measurements, balancing of the traverse, is done by
The branch of surveying in which both horizontal and vertical positions of a point, are determined by making instrumental observations, is known
