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

At what angle should a highway curve of 610-ft diameter be banked to accommodate
cars travelling at 105 mph? The coefficient of friction between the tires and the road is
