Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

Question

A segment of a highway was designed for a free flow speed of 90 mph. At the time of
observation along the segment, it was recorded that same segment was at its maximum
flow. What is the average speed of vehicles at this instant?
