1. The driver of a vehicle traveling at 80 kph up a grade requires 9 m less to stop after he applies the brakes than the driver travelling at the same initial speed down the same grade. If the coefficient of friction between the tires and pavement is 0.50, what is the percent grade and what is the braking distance down the grade. V=80 kph brakes are applied S-9 V,=80 kph V2=0 brakes are -S- applied

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.
