Speed bump that responds to your speed

No related posts.


Every driver knows the feeling… When you drive nicely under the speed limit towards a speed bump, this frustration starts growing. You already know that, even though you drive slow, your car will be launched. And that is exactly the same feeling as being punished while you didn’t do anything wrong. Why are you being punished for following the rules? Finally some designers have tried to come up with a solution.

On Yanko Design we found a product by designers Jae-yun Kim & Jong-Su Lee. THey designed “a speed bump that’s based on retractors that open if the impact with them is small enough. These speed bumps can be configured so that if a car is going below 30km/h, the speed bump flattens; over 30km/h, the force causes the retractor to stay closed, keeping the speed bump active.”

The fact that all drivers are being punished by speed bumps will finally end. People who drive slowely will finally get a positive advantage over people who speed. Smart and hopefully soon to be developed.

    So, if you approach it at the appropriate speed limit, then the bump will remain flat? if not it goes higher?….mmm… maybe its height should be proportional to the car’s approaching speed :)

  2. But this speed bump will still be an unneccessary hurdly for police cars, firefighters and ambulances. :(

  3. Of course police cars, firefighters and ambulances have a device on board which sends a signal :) This way the bump will go flat.

    It appears this speed bump is a completely passive design. It doesn’t contain electrical, pneumatic or hydraulic actuators, so it wouldn’t be possible for emergency vehicles to send a signal to it to keep it flat. Using passive means, it is merely flattened by the weight of a slow-moving vehicle, while the built-in dampers don’t allow it to move quickly enough to flatten for a fast-moving vehicle. I suspect it also wouldn’t flatten for a lightweight vehicle, such as a motorcycle, motor scooter or bicycle, but if it isn’t too wide, it might provide a means for two-wheeled vehicles to avoid the bump by going around its ends.

    It remains to be seen if these dampers can be built reliable enough to work trouble-free for 5 to 10 years while exposed to dust, mud, ice, snow, hot summer sun, and thousands of heavy vehicle crossings. Looking at the image accompanying this article, I have my doubts.
