It’s something most of us have experienced virtually every day, yet probably never thought about for an instant. Tactile paving is designed to help the blind or otherwise vision-impaired people find their way via textured surfaces on the ground. In London, for instance, they indicate everything from an impending drop in the curb to the presence of a stoplight at a crossing at a train platform. They need to be limited in size, since tactile paving can be difficult on walkers with arthritis. They also need to be consistently applied, since changing a pattern for those dependent on them is equivalent to deciding that a sign labeled “STOP” should sometimes mean “GO.”
