A car was traveling at a speed of 50mph. The driver saw a road block 80 m  ahead and stepped on the brake causing the car to decelerate uniformly at 10 m/? 2 .  a.) Find the distance travelled by the car during perception reaction time. b.) Find the distance travelled by the car from the moment the driver stepped on the brake until the car stops. c.) Find the distance from the roadblock to the point where the car  stopped.  Assume perception reaction time is 2 seconds

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.
