Speed Bumps vs. Speed Humps
What is the Difference Between a Speed Bump and a Speed Hump?
A speed bump at its highest point is 6 inches high; that sudden steep increase in height from the road is what gives the car a good shaking. These are used when speeds need to be kept relatively slow, about 5 miles per hour.
The speed hump on the other hand is a bit more forgiving. They vary in height but typically stay in the 3 to 4 inch range, allowing drivers to take them a bit quicker. These are designed to be driven over between 15 and 25 miles per hour, and effectively keep the majority of drivers in the 10 to 30 mile per hour range.
Both speed bumps and humps are typically placed between 250 and 500 feet apart. The closer together they are the slower the flow of traffic will be.
Where to put a hump instead of a bump
We recommend keeping speed humps primarily in residential areas or commercial spaces. They allow drivers to maintain a decent speed without hindering traffic flow too much, but will prevent anyone from dangerously speeding in front of your home.
Speed bumps on the other hand are great for parking lots and private roads. In areas with lots of pedestrians and moving vehicles, speed bumps work best. They will keep speeds very low and force drivers to pay extra attention. This is great for parking lots or any place similar where people and cars must share the same area constantly in close proximity.
