What is the maximum velocity in miles per hour, for an automobile rounding a level curve of 200 ft radius if the coefficient of friction between tyres and roadbed is 0.9? Correct answer is 51.91 mph.

Q: Determine the braking distance downhill and the percent grade of the highway at that section of the…

A: Velocity (V)= 55 mph Coefficient of friction = 0.30lets say breaking distance when driving uphill =…

Q: A moving car is traveling at 80 kph when the brakes are applied to it. The car still moves at a…

A: From the given data Speed V = 80 kmph = 80*5/18                 = 22.222 meter/sec Distance D = 35 m…

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.
