When it come to traffic calming and slowing devices, there are a few options. Speed bumps and speed humps are a solution, though these device terms are used interchangeably. However, there are differences between the two. Today, we at Andersen Asphalt & Striping would discuss the difference between speed bumps and speed humps.
Application & Function of Speed Bumps VS Humps
Speed Bumps. To ensure that vehicles slow to a craw, speed bumps have long been widely used in parking lots. By aiming to keep vehicle speeds down to about five miles per hour, this method reduces hazards for pedestrians. Encouraging drivers to slow down to avoid discomfort, the short travel distance to cross a speed bump ensures a sudden jolt to the vehicle as each axle passes over.
Speed Humps. Speed humps have a gentler slowing use. Where speed humps exist, traffic can continue to drive safely at fifteen to twenty-five miles per hour. Although mostly in residential areas where the speed limit is fairly low since speed humps are used on public roads. Since they can obstruct traffic flow, they’re usually saved for private roads and parking lots though speed bumps are occasionally also used on these types.
Effectiveness of Speed Bumps & Humps
Their greater height (six inches) offers speed bumps slow traffic more as well as a much more sudden bump than that of a three or four inch high speed hump. Rather than simultaneously, the speed hump is usually long enough that the up-and-down changes in road height are felt one at a time. The speed hump provides two relatively gentle motions rather than the jolt a speed bump produces as a result. Consider:
– Speed Humps should be for public roads to slow traffic to a safer speed
– Speed Bumps slow traffic to a crawl and should be used for private roads and parking lots
Get Speed Bumps or Humps Installed in Your Neighborhood
Although there is a difference in installation time because a speed hump covers more road surface, the installation process is broadly similar for both speed bumps and speed humps. Depending on what type of material is used, there are different installation processes. Installed by bolting a pre-formed piece to the road, rubber or plastic devices, which have more give and are less likely to damage vehicles. Until the desired height is reached, those made of traditional asphalt are installed by layering asphalt. Though there is a slightly increased chance of damage to vehicles that pass over without slowing, making it more effective at slowing traffic, due to asphalt’s density when layered. Recommendations:
– For the installation time and type of material, plan ahead
– For your type of road, choose the right style
Speed Bump & Hump FAQ
Q. How efficient are speed humps?
A. At reducing traffic flow to 10 to 30 miles per hour is what speed humps are effective.
Q. Are the speed bumps required to be marked?
A. To give time to slow their vehicle, speed bumps should be clearly marked.
Q. Can damage to cars occur from speed bumps?
A. If they pass over the bump without slowing down, speed bumps can damage the underside of cars.
Q. Do speed bumps require planning permission?
A. From the landowner or local governing body, permissions are usually required since speed bumps are often bolted into the ground.
