A vertical curve is to be constructed between a 2.5% grade and a -3.5% grade. The required sight distance is 305m. The dangerous object is considered to be on the pavement surface, and the driver's eye level is at 1.05m above the pavement surface. Determine the length of the vertical curve that will satisfy the sight distance requirement.

Q2: Determine the minimum length of the curve between - 0.7% grade and a +0.5% grade for a road with 110 km/h design speed. The vertical curve must provide 220 m headlight distance. * Your answer
I need right solution with clear calculations. A curve is required to connect an entry grade of +3% and an exit grade of +2% to satisfy a sight distance requirement of 250m. Determine the minimum length of the curve assuming an average driver eye height and hazard is at the level of the carriageway.
Determine the minimum length of a vertical curve between a -1.78% grade and a -7.8% grade for a road with a 110 km/h design speed. The vehicle approaches the curve from the side of -1.78% grade. The vertical curve must provide the sufficient stopping sight distance and meet the appearance criteria. For stopping sight distance the both vehicle and object are located within the vertical curve. Consider a new road with a single carriageway in each direction, Rt=2.5s, d=0.29, h1=1.1m, h2=0.2m, height of headlight = 0.65m and q=1 degree.

If the design speed is 65 mi/h, determine the minimum length, in ft, of vertical curve. Part B. If the design speed is 65 mi/h, determine the elevation, in ft, of the point of vertical tangency also known as end of vertical curve. Part C. If the design speed is 65 mi/h, determine the elevation, in ft, of the highpoint of the curve. Part D. If the design speed is 65 mi/h, determine the distance, in ft, from the point of vertical curvature (also known as the beginning of curve) to the highpoint of the curve.
