From which three positions are road curves staked?

When laying out a road curve, you need clear reference points that define the curved path and guide construction along its length. The essential anchors are the start of the curve, where the road transitions from a straight tangent into the arc, and the end of the curve, where the arc meets the next straight tangent. Those two points are called the Point of Curvature and the Point of Tangency. To keep the curve accurate through its entire length, you also place reference stakes at intermediate locations along the curve. So the three staking positions are the start (Point of Curvature), the end (Point of Tangency), and an intermediate setup along the curve. This combination provides the necessary start, end, and along-curve guidance to transfer the design onto the ground reliably. Other terms like Beginning/End of Curve are synonyms in some contexts, but the standard staking practice emphasizes PC, PT, and intermediate points rather than the intersection point of the tangents, which isn’t a stake position on the curve itself.
