Speed Hump - Rubber, 12-14 Feet Length, 3-4 Inches Height | Parabolic Shape, Black And Yellow Color, Surface Mounted

A speed hump is a rounded traffic calming device used to reduce vehicle speed and volume on residential streets. Humps are placed across the road to slow traffic and are often installed in a series of several humps in order to prevent cars from speeding before and after the hump. Common speed hump shapes are parabolic, circular, and sinusoidal. Generally, speed humps are 12 to 14 feet in length and span the width of the road. The height of humps ranges from 3 to 4 inches. The length and height of the speed humps determine the speed at which traffic will travel over the devices. Shorter lengths and greater heights slow cars most drastically. When placed in a series 350550 feet apart, humps will reduce 85 percentile speeds by 810 mph. A warning sign notifies motorists before humps.
