Question

Vertical curves transportation highways.

Answer 1

vertical curve provides a transition bA vertical curve provides a transition between two sloped roadways, allowing a vehicle to negotiate the elevation rate change at a gradual rate rather than a sharp cut. ... These curves are parabolic and are assigned stationing based on a horizontal axis

Answer 2

Vertical Curves are use in highway and street vertical alignment  to provide a gradual change between two adjacent grade lines.

Answer 3

Vertical curves are used in transportation highways to provide a smooth transition between two different grades. They are used to ensure that vehicles can safely traverse the highway without experiencing an abrupt change in elevation. Vertical curves are usually designed using a parabolic curve, which allows for a gradual and safe transition between two different grades.
