Tactiles (also called truncated domes, detectable warnings, Tactile ground surface indicators, detectable warning surfaces) are unique non-fade, non-slip ground surface indicators. These indicators provide cues, which combined with other environmental information, assist visually challenged people with their orientation.

Tactile warnings provide a distinctive surface pattern of "truncated domes" (which are small domes that have had their tops cut off, or truncated) or "truncated bars" detectable by long cane or underfoot which are used to alert visually challenged people of their approach to streets and hazardous drop-offs - thereby alerting them of impending danger from oncoming vehicles or a change in path gradient.

Tactile ground surface indicators are an important and mandatory design element in all modern construction and public infrastructure projects. The Johnson Endura Hi-Traffic Tactile collection has been designed with emphasis on reliability, safety, dignity and independence for visually challenged people.

Red Ramp Project is
supported by
An initiative by for an access friendly India


The geo-tagging facility would help us to get your suggestions about the likely places where access to physically challenged people is difficult or not there. It will be applicable within India excluding the state of Jammu and Kashmir. The actual activity of building a Ramp or an Access facility can involve several technical, environmental or regulatory issues. The final decision of building a ramp will be at the sole discretion of H&R Johnson.
