Most highway vertical curves are designed using a:
Correct answer: B. Parabolic curve
- A. Circular curve
- B. Parabolic curve
- C. Spiral curve
- D. Compound horizontal curve
Explanation
A parabolic vertical curve provides a gradual change in gradient and gives a convenient relationship between elevation and distance. Spiral and compound curves are mainly associated with horizontal alignment rather than ordinary vertical curves.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
