Escalators, Travellators and Mechanical Ramps

Travellators are considered complementary elements of accessible pedestrian paths and shall have the following requirements:


1. The moving surface shall present a maximum gradient of ≤5%.
2. The beginning and the end of travellators shall present a contrasting pavement with the surroundings.
3. The direction of travel shall be marked.
4. It is recommended to install an audio system indicating the start and end of these devices.

 

Escalators and mechanical ramps are not considered part of the accessible path.

 

Whenever provided they shall be accompanied by a non-mechanical accessible alternative route or an elevator that leads to the different levels.

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.

Pendulum test value (PTV) is a measurement of the slip resistance of a floor surface, either an external or internal floor of a building. The least slip resistance a surface material is, the more likely people may skid or trip, especially in wet conditions. In average circumstances, slip-resistance is as follows:

0-18 = very low slip-resistance.

18-25 = moderate slip-resistance.

25-36 = good slip resistance.

Light Reflectance Value (LRV) is a numeric scale that is used to identify how much light a colour reflects or absorbs. It is used in universal design to identify the contrast between two colours. This can help to determine if there is sufficient contrast to visually identify a feature such as a fonts on a sign, elevator call button, a handrail and other items which need to be seen by visually impaired people.

The interaction space is the space required by a person to interact with another person, furniture, appliance, machine or another element.
