An ascending grade of 5% and descending grade of 4% are connected by a parabolic curve. A motorist passing on the curve and whose eyesight is 1.5 m above the pavement could just see the top of a visible object 130mm high at a horizontal distance of 160 m. Determine the length of the parabolic curve connecting the gradelines.   a. 457.83   b. 425.48   c. 458.38 m   d. 424.98

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
