Introduction
The nature and extent of visual impairment varies considerably among individuals and are very different
from person to person. Generally, the result of different eye conditions can lead to the following types of
impairment:
— a limited field of vision, being unable to see to the sides or up and down;
— some loss of central vision limiting the ability to see fine detail;
— acute short-sightedness, seeing the world as a continuous blur;
— uncontrollable oscillations of the eyeball leading to an inability to see objects clearly;
— night blindness, a sensitivity to light and a tendency to be dazzled by glare;
— disease can also lead to vision loss and blindness.
Visually impaired people detect information about the environment by the use of non-visual features, for
example, audible and tactile features. A loss of sight is not accompanied by an increase in the effectiveness
of other non-visual senses. However, visually impaired people generally place more emphasis on
information received via other senses, for example the sense of touch.
The use of tactile information: when moving around the pedestrian environment, visually impaired
people, using a range of mobility equipment including the long cane, will actively seek and make use of
tactile paving surface information, particularly detectable contrasts in surface texture.
The ability to detect contrasts in texture underfoot varies from one individual to another. For example,
older visually impaired people and people who have lost their sight through certain medical conditions,
such as diabetes, can have reduced sensitivity in their feet.
It is important that tactile warnings of potential hazards, e.g. a road crossing or a stair, are rigorous
enough to be detectable by most people but without constituting a trip hazard or causing extreme
discomfort.
Considering the walking speed and the length of one step by a visually impaired pedestrian, the width of
any warning surface is a critical parameter.
Visually impaired people who have some residual vision will make use of the luminance contrast between
surfaces for orientation and guidance, in addition to tactile information. To provide visual and tactile
guidance as well as to accentuate the presence of hazards and amenities, luminance contrast between
tactile paving units and the adjacent surface needs to be considered by designers, planners, engineers
and others involved in the design of the built and pedestrian environments.
Whereas this document covers the measurement of light reflectance values of individual units, it does not
cover the required criteria necessary to enable designers to implement adequate luminance contrast
since this relies on the difference between adjacent surfaces, which do not both need to be tactile surfaces.
However, manufacturers should be aware of this issue in considering the range of colour and tones they
provide in their tactile products. Methods for measurement of light reflectance values and the colour of
individual units are proposed in this document.
This document is not intended to set requirements for the layout of tactile paving units, but to allow
manufacturers to place their products on the market with a CE marking. It is intended that layouts and
the specific layout of individual tactile profiles within units will be set locally taking into account
regulations, codes of practice, standards and guidance at the place of use and be within the ranges given
in this document. Where no local guidance is available default values are given which should be used.
