An equal tangent vertical curve is intended to connect grades of 5% and -2.5%. If this curve is to be a part of a highway designed with a PSD of 450ft, determine the minimum length (ft) of the vertical curve. Use exact solution (do not use the table). Round your answer to 3 decimal places.
3. A -4% grade line (400 ft length) intersects a -2% grade line (200 ft length) at station 63+00, where the elevation is 949.50 ft. Determine elevations at 100-ft stations for this 600-ft unequal-tangent curve.
2. Compute by hand and tabulate station elevations and the 1st and 2nd differences for an equal tangent parabolic (vertical) curve for the following data: A +3.50% (g1) grade meets a -4.00% (g2) grade at Station 12+65 (the PVI). The PVI Elevation = 300.00'. Length of Curve = 750'. Calculated elevations for full stations between the BVC and the EVC. Also, calculate the station and elevation of the curve for the PVI, BVC, EVC and the High Point. Place all the information in station order in a properly labeled and organized table using the exact format shown in the last slide of the Application of Vertical Curves Video. Show all elevations to 3 decimal places. Provide a page sized detailed and labeled sketch of the profile of the curve. Deliverables: Your calculations, sketches and tables should be submitted by the syllabus deadline as a properly named single PDF document. The order for the information in the submission PDF is to be as follows: Problem 1 Hand Calculations Problem 1…
A vertical road was designed with three tangent lines having a grade of 7.3%, -3.9 %, and 2.8%, consecutively. The intersections of the three lines are known to be V1 and V2 having an elevation of 226.10m and 202.03m respectively. The said tangent lines will be connected by a summit and a sag unsymmetrical parabolic curve which meets at point A having an elevation of 216.29m above sea level. The L1 of the summit curve is 106.73m and the maximum offset of the sag curve is 0.51 multiplied to the maximum offset of the summit curve. Point A is located at the line that connects the two vertices. What is the elevation at the end of the road in meter?

A vertical parabolic curve is to be used under a grade-separation structure. The curve is 250 m long and the minus grade of 3.8 percent intersects the plus grade of 5.4 percent at station of 0+120.424. Calculate the low point of the curve if the intersection at station 0+120.424 is at elevation 230.085 m.
An equal-tangent equal tangent vertical curve connects a +2.10% initial grade and -2.70% final grade. The PVT is at station 127+18 and elevation 206.52 ft. If the design speed is 75 mi/h, what is the elevation of the curve at station 121+58? You answer must be in ft and rounded to the second digit, if you need to use values from tables, use "design" values (usually last column), not "calculated".
Two tangents in profile meet at a vertical point of intersection (VPI). The entrance tangent grade is +5%. The exit tangent grade is -3%. Point on Tangent 1 (POT1) is on the entrance grade. Point on Tangent 2 (POT2) is on the exit grade. An equal tangent vertical curve of 1000.00 ft has been designed to provide a smooth transition between them.
