In transportation planning, an origin-destination survey is mainly conducted to determine the:
Correct answer: A. Sources and destinations of individual trips
- A. Sources and destinations of individual trips
- B. Number of vehicles using each pavement layer
- C. Strength of soil beneath the roadway
- D. Superelevation required on road curves
Explanation
An origin-destination survey records where trips begin and end, along with related travel information. This helps planners study travel patterns and forecast future transport demand.

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.
