It's always been convention that the stationing from the beginning of a horizontal curve to the point of intersection is equal to the tangent, and the stationing between the beginning of the horizontal curve to the end of the curve is equal to the length of the curve. I've been just accepting it because that what the book says, but how does it make sense? How would it be mapped out in real life? I would think that we need to station from the tangent or station from the curve, but why then do stations work like I described? Thanks.
