The sketch following shows the traverse from A to B, along the horizontal alignment of a rural highway. A circular curve joins the points BC and EC. The Y and X coordinates of points A, PI and B are given in the table below. Assume point A is situated at chainage 0+000. PI EC BC Beginning of the circular curve End of the circular curve.
