Correct answer: D. Number of days in the year
- A. Number of peak hours
- B. Number of working days
- C. Number of lane kilometres
- D. Number of days in the year

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.
