The aim of the study is to determine and prioritise the characteristics of the built environment that increase the effectiveness
of the walking surfaces for blind and vision-impaired people. Tactile walking surface indicators are installed on
the floor of indoor and outdoor built environments for guiding blind or vision-impaired people. These people perceive
the walking surface by a long white cane, through the soles of their shoes or impaired vision. Based on the relevant
research and published standards there is a consensus on the characteristics of tactile working surfaces in terms of
design specifications, visual contrast, material and installation requirements.
In order to have the right decision while using the related knowledge, the designer of a built environment should identify
and prioritise the characteristics of the users. The findings of factorial analysis showed that the individual characteristics
such as shoe width, stature, gender, and frequency of leaving residence and experience alone, or with help, determine
the effectiveness of tactile surface indicators as the primary factor. The second important factor that can be named
as perceptual characteristics of the individual is composed of long white cane usage, time of sight loss and visual efficiency
type. It is found that ease of walking on tactile surfaces as ease of change in direction, ease of stay on proper
course of walking and transition from truncated domes to bars are third in priority as long as they comply with the standards.
