A vertical curve joining a (-5%) and (+3%) grades in a rural highway has a design speed of 100kph. The tangents intersect at a station (225+71.35) at an elevation of 290m. Caleulate the elevations of intermediate points on the curve each 100m, and determine the stations and elevations of PVC, PVT. It s important to know that the driver acceleration rate is 3m/sec2 and the perception & reaction time is 2.5 seconds.
