A driver of a car applied the brakes and barely avoided hitting an obstacle on a roadway section which has a 5 percent gradient. The vehicle left skid marks 26 meters. Assuming that the coefficient of friction is 0.6 and the driver was travelling down the grade; determine whether the problem was the speed limit of 70kph on the section or driver violation of the speed limit.

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.
