For a highway crest curve, the required length is commonly controlled by providing adequate:
Correct answer: C. Overtaking or stopping sight distance
- A. Drainage gradient
- B. Pavement skid resistance
- C. Overtaking or stopping sight distance
- D. Railway cant deficiency
Explanation
Crest vertical curves must provide sufficient visibility over the summit. Depending on the design case, stopping sight distance or overtaking sight distance controls the required length.

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.
