India’s Crosswalk Illusions are More Effective Than Speed-Bumps

To get drivers to slow down at crosswalks, India is experimenting with painted optical illusions instead of speed-bumps. Created by artists Saumya Pandya Thakkar and Shakuntala Pandya, the street paintings appear to be 3D road blocks as drivers approach, forcing them to slow down in their confusion. As they get closer, it becomes apparent that the blocks are actually flat, so drivers don’t actually come a complete stop. And so far the experiment seems to be working—no accidents have occurred at the upgraded intersections.
