Fake Speed Bumps

This could be an answer to the speeding around the Shawnee High School. 3D optical illusion speed bumps are being used in Philadelphia. In an effort to slow down drivers speeding through local streets. They are intended to trick drivers into slowing down only later to find that there was no bump at all. They caution you to slow down because you don't know what you are facing. They can also remind drivers that they need to slow down because they are in a School Zone. They are made by Japan's Sekisui Jushi Corp. and contain reflective glass beads. They require little engineering or planning and can work in places where real bumps may not be acceptable.


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,
