Tactile Dome

Small raised bumps arranged in a grid pattern on ground surfaces to provide a tactile warning of an upcoming hazard, such as a curb edge, train platform edge, or street crossing. Tactile domes are part of the broader category of tactile walking surface indicators and are typically required by accessibility standards at curb ramps and transit platforms. They can be detected underfoot or with a white cane, alerting people with vision loss to surface level changes. The contrasting color of tactile domes also provides a visual cue for people with low vision, helping them locate curb cuts and transitions from a distance.
