Internal Corridors

  • The width of corridors free of obstacles should be enough to allow all users passage in both directions, according to the building’s use, considering a minimum of 1000 mm per each simultaneous pedestrian.
  • Where there are direction changes (180º and 90º), the clear passage width shall allow a manoeuvring turning space of 1500 mm diameter.
  • Floor surfaces shall be firm, smooth, stable, and level, without glare and slip resistant avoiding vibration in wheels produced by excessive joints. Rugs and carpets should be firmly fixed to the floor and not have a high pile.
  • The accessible pedestrian walking path shall present reflectance contrast with the pavement not intended for walking of at least 30 points LRV (Light Reflectance Value) and/or by an easily perceptible (by the foot or the cane) texture difference.
  • A tactile warning surface shall precede any sudden level change.
  • The average minimum illumination is 100 lux calculated at floor level, with a minimum value of 60 lux.

Glossary of Terms

LUX is a unit of illumination equal to the direct illumination on a surface that is everywhere one meter from a uniform point source of one. It is used in universal design to determine if an area is adequately lit by natural daylight or artificial lighting so people with poor vision are able to navigate a space safely.

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.

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.

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.

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