NHTSA Tests Illusional Speed Bumps

Posted by Sheila Franklin Categories: Science, Transportation

Speed BumpsThe National Highway Traffic Safety Administration is testing a fake speed bump to see if drivers will slow down. The optical illusion looks like a 3-D pyramid when seen from a distance. The first experiment in Phoenix seemed to work until drivers realized that there were no barriers. This time the NHTSA will run a larger test in a Philadelphia residential area, hoping that they will reduce pedestrian accidents. The markers only cost $60.00 to $80.00 apiece as opposed to real speed bumps which can run $1,000.00 to $1,500.00. At least they are acting reasonably about the devices that they realize will probably have only the same effect as flashing lights.

If they work great. I think that they should also throw a few real ones in just for good measure.  Keep the driving public guessing.

They have a quite a few of these down in Calgary here. Not the same image but a painted image and it really does work I fall for it every time lol.

Might help with pedestrians getting hit. People need to slow down and watch the roads more. I know where I am people havent been wanting to pay any attention the speed limit and get mad if they are behind you and you are doing the speed limit. I havent seen any of these speed bumps but I think we might benefit from them if we had them.

They arent mean’t to help pedestrians from getting hit. They are simply there to reduce the cost of what it would cost to place a speed bump.
