A Truncated Dome is a standardized textured surface made of small, flattened domes arranged in a grid pattern to provide tactile alerts and directional information for individuals who are blind or have low vision. Truncated domes are commonly installed at curb ramps, transit platforms, and building entrances to signal a change in environment or the need to stop and assess surroundings. The alignment of the domes indicates the safe direction of travel. Truncated domes are especially important for white cane users to detect transitions and potential hazards.
