Green Speed Bumps Would Save Fuel, Lower Emissions

How can a speed bump lower the amount of gas drivers use, as well as tailpipe emissions? By being a fairly brilliant speed bump.

So-called “green” speed bumps, engineered by designers Jae-yun Kim and Jong-Su Lee, can sense a vehicle's speed as it approaches. If the car is traveling at a steady, pre-determined speed, the bumps will flatten so the car can continue. If it's going too fast, they will stay raised, warning the driver to slow down.

The goal is to get drivers moving at one low, consistent speed. You know how when you come to a stretch of speed bumps you sometimes speed up in between them, then slow down just as your car nears the behavior-adjusting bump? That is incredibly inefficient and economically and environmentally brain-dead.

The goal of the green speed bump is to reward drivers who are doing it right, essentially by incentivizing the speed-bump-encounter experience. Let's hope we see them on roads soon.

MOST STUPID GIZMO

Lets put them on the highways :o))

My problem with alot of speed bumps is that they are to steep and the bump is too hard. This is taken after the fact that I do slow down to go over them. Trying mistakingly going over them just a wee bit to fast, your understand quick. The other problem is that I think they are made bigger for SUV. Therefore people driving cars like me suffer.

So, are they being tested in Korea?

Sounds useless to me. If people are going to drive fast, they still drive fast regardless of the height of the speed bumps, especially the 4x4 truck drivers, those trucks are built to defeat these bumps.

These are easily vandalizable. I can see a couple of hammer swings permanently removing them :o)
