A vertical curve is to be designed to join a -5% grade to a +2% grade. If the design speed is 50
kmhr, determine the minimum length of the curve that will satisfy stopping sight distance criteria.
Assume standard values for a,g,PRT, h , and beta.
Then, determine the rate of vertical curvature and the corresponding minimum length
of the curve.
