Detectable Warning Systems are Making Transit Safer

Approaching an escalator, waiting at a crosswalk or standing on the platform watching the train approach; it’s likely you have seen detectable warning systems installed in these areas. Tactile walking surface indicators, (TWSI) are comprised of truncated domes or wayfinding bar tiles. These tactile warning systems, that stick just mere millimeters out of the ground’s surface, provide an easily detected warning of potential hazards.
