Note:- Hi! Thank you for the question, As per the honor code, we are allowed to answer three sub-parts at a time so we are answering the first three as you have not mentioned which of these you are looking for. Please re-submit the question separately for the remaining sub-parts.
During gradient variations, vertical curves are added to prevent collision and preserve clear visibility. To smooth out all the angles and produce a gradual shift in gradient, they are laid out on a vertical plane. Although either circular or parabolic vertical curves might well be employed, the latter are more frequent.
