The length of a highway is 550 m when a head-on vehicle collision occurred. Police reports show that neither human error nor vehicle malfunction was the cause of the collision. Check if the length of the highway is sufficient for an overtaking maneuver. *Accident Report: Speed of Overtaking Car = 96 kph, Speed of Overtaken Car = 88 kph, Perception-reaction Time = 2.5 sec, Average acceleration = 2.4 m/sec2, Time of the passing vehicle occupying the left lane = 10.4 sec, Distance between the passing vehicle at the end of its maneuver and the opposing vehicle = 84m.

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.
