For a signalised intersection, saturation flow is best described as the:
Correct answer: C. Maximum discharge rate of a lane under continuous green
- A. Total traffic volume entering the intersection daily
- B. Average number of vehicles waiting during red
- C. Maximum discharge rate of a lane under continuous green
- D. Time required for pedestrians to cross the road
Explanation
Saturation flow is the maximum rate at which vehicles can discharge from a lane when a continuous green signal is available and the queue is present. It is usually expressed in vehicles per hour of green. Queue length and pedestrian crossing time are separate measures.

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.
