Transcribed Image Text:A basic highway curve connecting two straight sections of
road is often circular. In the figure, the points P and S mark
the beginning and end of the curve. Let Q be the point of
intersection where the two straight sections of highway
leading into the curve would meet if extended. The radius
of the curve is R, and the central angle denotes how many
degrees the curve tums.
