A vertical curve is designed to join a roadway grade of +3% to a grade of -2.5%. The design speed of the road is 100km/hr. The stake value and elevation of the PVI is given as 1+000m and 100m respectively. Further, the midpoint of an overhead power transmission line crosses the road at stake value 1+100m and at an elevation of 118m. a) Determine the minimum length of vertical curve so that a stopping sight distance (distance required for stopping safely) of 180m is accommodated. b) Determine the stake value and elevation of the PVC, PVT, and highest point of the curve. c) Determine the available vertical clearance from the road to the midpoint of the transmission line
