This paper summarizes research conducted by the Centre for Logistics and Transportation (CCLT) over the past four years, concerning tactile surfacing to aid visually impaired people. In 1989, CCLT began research to determine how many different textured surfaces could be reliably distinguished by visually impaired people. Also, the research examined the extent to which the surfaces might cause problems to other footway users. Five different tactile surfaces were found to be of use in providing warning and guidance for visually impaired people. In 1990, these surfaces were tested in 'real life' pedestrian environments to assess their usefulness. More recent research investigated the use of tactile surfaces in improving the safety of railway stations for visually impaired pedestrians. Also, CCLT has conducted research concerning the frequency and types of accidents experienced by visually impaired pedestrians.
