Guiding Tactile Pavements

Tactile Surfaces

Tactile pavements shall have a reflectance contrast with the surrounding pavement of at least 50 points LRV and the height or depth of this pavement cannot be greater than 4mm.

Tactile pavements must be installed according to the following criteria:

1. Detectable warning surface: used as a warning of upcoming level changes or obstacles on the course of travel. Warning pavement shall be constructed of truncated cones arranged in a square grid or diagonal rows and installed with bands oriented in the crosswise direction of the course of travel. It must be installed along the entire width of the element and not less than 300 mm from the beginning of the dangerous element. The warning surface shall have a width between 300 mm and 400m.

The most common elements where warnings are required include stairs, ramps, rail and port platform borders, and unprotected changes in level among others.

2. Tactile guiding surfaces: this element is used as a directional sign to assist the independent mobility of people with visual disabilities. Guiding patterns should be constructed of flat topped elongated bars. Bars must be oriented in the direction of the course of travel.

The tactile guiding surface shall have a minimum width of 400 mm. The distance among longitudinal stripes can’t exceed 32 mm.

Glossary of Terms

Tactile pavements are textured surfaces with contrasted colour that are perceptible and identifiable by feel or cane or residual functional vision that warns or informs people with visual disabilities.

Truncated domes in a grid pattern to provide a tactile surface under feet of blind users. They are used as a used as a warning of upcoming level changes or obstacles on the course of travel.

Flat topped elongated bars in the paving surface under feet of blind people. They are used as a directional sign to assist the independent mobility of people with visual disabilities.
