Road signs suck. What if we got rid of them all? Some cities in Europe are undergoing a fascinating transformation: they�re getting rid of all of their road signs. That�s thanks to a design concept called �shared space,� where urban planners drastically lessen the presence of traffic lights, signs, and barriers, encouraging all forms of transportation to share the road. There�s evidence that drivers often totally ignore road signs, so the heightened risk forces commuters to remain on high alert as they pass through an intersection, in theory leading to safer travel.
