The Globe and Mail reports:

Motorists travelling on 22nd Street in West Vancouver will be confronted with a 3D image of a little girl chasing a ball in the street starting next Tuesday. The girl will be an optical illusion, but the scenario is very real, according to David Dunne of the BCAA Traffic Safety Foundation.

I'm not sure it's such a good idea due to the fact that a driver could swerve or stop suddenly, causing a crash, but it should make a point and hit home with some.
