Engineer Ali is designing a crest vertical curve for a highway heading

Engineer Ali is designing a crest vertical curve for a highway heading to Mt. Hood, where the speed limit is 65 mi/h. The curve is 1100 ft long and has its PVC at station 125+00. The PVC elevation is 1000 ft. The initial grade leading to the curve is +2.5% and the final grade is -2.0%. (a) Determine the elevation and stationing of the high point, PVI, and PVT. (b) Does this curve satisfy stopping sight distance requirements?
