Speed Humps vs. Bumps: A Road Bumpy Breakdown

Ever hit a bump in the road that jolted your car and rattled your teeth? These aren't just annoying obstacles; they're speed humps or bumps, traffic calming devices designed to slow vehicles down. While they may seem like twins separated at birth, humps and bumps have some key differences:

Habitat:

  • Humps: Prefer the open streets, often found on low-volume roads and residential areas.
  • Bumps: More at home in confined spaces like parking lots and driveways.

Speed Limit:

  • Humps: Like it slow and steady, typically keeping speeds around 15-20 mph.
  • Bumps: Can handle a bit more pace, slowing cars down to 10-15 mph.

Height:

  • Humps: Rise proudly, reaching heights of 3-4 inches with a gentle, parabolic curve.
  • Bumps: Keep it short and sweet, usually staying under 3 inches and featuring a more abrupt bump.

Purpose:

  • Humps: Aim for a smooth slowdown, encouraging drivers to be mindful of their speed for a longer stretch.
  • Bumps: Deliver a sharper jolt, forcing a quick reduction in speed, especially effective in tight spaces.

Who invented them?

Interestingly, both humps and bumps owe their existence to physicist Arthur Holly Compton. He invented these "traffic control bumps" in 1953 to curb speeding near his university, paving the way for safer roads for everyone.

So, next time you encounter a bump in the road, take a moment to appreciate its role in keeping pedestrians and drivers safe. Whether it's a gentle hump or a jolting bump, they're both working hard to smooth out the traffic flow and keep our streets a little less bumpy.
