WHERE ARE THE KINKS IN THE ALIGNMENT
This paper uses the tangent method to determine the maximum length of an approach to a curve so that the driver does not see a kink (a sudden change in direction) in the alignment. Equations are presented for plan curves, crest curves, sag curves, and combinations of these curves. The picture presented by the road to the driver can be analyzed with the equations, and, thus, the road design engineer is able to relate important road properties to driver experiences. It is suggested that using this method to check road alignment design for kinks reduces the need for the time-consuming process of drawing perspectives.
