I came across this on the CNN News site. I think it’s a great idea, basically it’s a fake speed bump; a flat piece of blue, white and orange plastic that is designed to look like a 3-D pyramid from afar when applied to the pavement.
These fake bumps are being tested on a section of road in Philadelphia’s northeastern corner. But soon they will also be popping up (or looking that way!) on 60 to 90 more streets where speeding is a problem.
The 3-D markings are appealing because, “at $60 to $80 each, they cost a fraction of real speed bumps (which can run $1,000 to $1,500) and require little maintenance.”
However apparently after a few months, their effect wears off. Which makes sense.
