Designers have implemented a “ghost roundabout” in Cambridge, United Kingdom to intentionally confuse speedy drivers. The new road feature consists of a circular pattern of cobbled bricks that resembles a traffic roundabout. The bricks are merely decorative; however, behavioral science dictates that the familiar circular shape will cause drivers to take notice and slow down. The formation has been criticized by those who believe it looks too much like a crosswalk or that the confusion it will cause drivers will be dangerous. By replacing vertical speed bumps, the “ghost roundabouts” could provide a slowing mechanism that no longer relies on giving the driver a physical jolt.
