Two curves on a highway have the same radii. However, one is unbanked and the other is banked at an angle of  30degrees. A car can safely travel along the unbanked curve at a maximum speed v0 under conditions when the coefficient of static friction between the tures and the road is µs. The banked curve is frictionless, and the car can negotiate it at the same maximum speed v0. Find the coefficient of static friction between the tires and the road.

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.
