They plan on using a 'scare tactic' that will remind drivers to slow down by painting an elongated image of a child chasing a ball onto the street on the pavement. When viewed from the vehicle, the 2-D image appears three-dimentional causing the speedy driver to panic and hit their brake. There is also a nearby sign that reads, "Your probably not expecting kids to run into the road."
From a distance it appears as more or less a smudge, but at a certain distance the stretched image becomes coherent to the driver and appears to rise from the pavement in 3-D. The faster the car is traveling, the faster the image pops into view.Although a 'clever' plan, this idea may backfire drastically... For example, cars may instinctively swerve out of the way and cause an accident regardless -or- drivers that are used to these street paintings may carelessly mistake a real child for the painted ones and drive over them...!
Either way the Optical Speed Bumps are being tested out for a week by authorities at the West Vancouver school zone and then they will evaluate the results.... I'm curious what comes out of it.
