Five cars are traveling at constant speeds 24, 31, 28, 35, 19 kph. respectively, in a uniform section of highway 4 km long. Determine the time mean and space mean speeds. Which one is higher, time mean speed or space mean speed? Can you think of the reason why this is so?

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.
