JAPAN’S Railway Technical Research Institute has carried out testing with blind passengers to develop a national standard for the installation of tactile paving which provides a warning of platform edges.

In an effort to reduce the risk of passengers falling from platforms, researchers have identified the optimal width of tactile paving for blind and partially- sighted users, as well as the distance from the platform edge at which the paving should be placed.

A tactile slab which combines raised dots with a linear projection has been developed to help passengers identify which side of the paving they can safely walk.
