1. An equal-tangent crest vertical curve is being designed for a speed of 45 mph. The curve connects grades of 1.3% and -2.4% in the direction of interest. The curve high point is at station 110+30 and has an elevation of 930 ft. What is the station and elevation of the PVC and the PVI? [Answer: PVI station: 110+50.3; PVI elevation: 930.6']
A-1.7% grade intersects a 3.6% grade on a highway with a design speed of 55 mph. What is the length of the curve in ft required? (Assume provisions are to be made for minimum stopping sight distance).
An equal tangent vertical curve is to be constructed between grades of -2.0% and +1.0 %. The PVI is at station 11 +000.00 and at elevation 420 m. Due a street crossing the roadway, the elevation of the roadway at station 11 +071.00 must be at 421.5 m. Design the curve. (what is the curve length?)
A crest vertical curve joining a + 3 percent and – 4 percent grade is to be designed for 75 mph. If the tangent intersect at station (345 + 6000) at an elevation of 250 ft, determine the stations and elevations of the PVC and PVT.
An existing vertical curve on a highway joins a +4.4% grade with a -4.4% grade. If the length of the curve is 82m, what is the maximum safe speed on this curve? What speed should be posted if 8kph increments are used?

A horizontal curve is designed for a two-lane road in mountainous terrain. The curve has adesign speed of 120 km/h, a deflection angle of 26º, and a superelevation rate of 6%. If the stationof PI is (12+300), determine:a) Minimum curve radius.b) Stations of PC and PT.c) Length of superelevation runoff.d) Also, draw a neat sketch for the superelevation development from the normal crownsection, where the normal crown slope is 2%, to the fully superelevated section byrotating the section around the centerline. Show all relevant distances and stations onthis sketch. Assume lane width, w = 3.6 m; maximum relative slope between pavementedge and centerline in the superelevation runoff, s = 0.38%

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.
