) The driver of an automobile moving with the velocity of 90 km/h on a 4% graded descending highway section decides to overtake the bus moving with a velocity of 70 km/h despite the approaching truck with a velocity of 50 km/h on the opposite direction. a) What should be the minimum distance between the automobile and the truck at the beginning of the overtaking for safe manouevre ? b) If the truck has to stop op the highway, what is the upper and the lower limit of the traction force that must be diverted to its wheels in order to restart moving ? Given: di=8+0,2.Vi ; pavement sliding coefficient, f=0,40; t = 0,020; the mass of the truck = 12 ton, Qm=2/3.Q

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.
