Q.No.1 Capital Development Authority (CDA) plans to provide a new connection between sectors G-9 and G-8 with the help of a highway. The new highway will run east-west and will pass over the 9th avenue (grade separated intersection) at right angle, at an elevation of 550ft. The elevation difference between the two highways is 30ft. Both the highways are level grade. A single-lane ramp is to be constructed to allow eastbound traffic to go southbound. A single horizontal curve, with a central angle of 90 degrees, is to be used. Required superelevation is 8%. Vertical alignment transitions from a crest vertical curve to a sag vertical curve through a constant-grade section. Design Speed (V) is to be calculated as follows: V(mi/h) = 50 + (your registration number) (Calculated design speed must be rounded down to the nearest 5mi/h multiple) Determine the following: Part 1 Horizontal Alignment: The stationing of the PC, PI, and PT, assuming the curve begins at station 60+00. Part 2 Vertical Alignment: Length of crest vertical curve (L) Length of sag vertical curve (Ls) Length of constant-grade section (Lcon) Elevation of: PVTc, PVC, PVTS Draw neat sketches clearly showing the horizontal and vertical alignments along with values obtained from the design.
