A motorist traveling at 55 mi / h down a grade of 5% on a highway observes a crash ahead of him ,involving an overturned truck that is completely blocking the road .If the motorist was able to stop his vehicle 30 ft from the overturned truck ,what was his distance from the truck when he first observed the crash? Assume perception-reaction time =2.5. f=0.35.

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.
