“…& In a review of tactile paving, the guidance (DfT, 2007b) would benefit from more emphasis being placed on the 'dos and don'ts' of tonal contrast, especially given that most people with a vision impairment have some residual vision so tonal contrast and the use of correct colours is hugely important for these pedestrians. & Research by others (Fujinami et al, 2005;Jansson et al, 2007) has shown that a smooth surface around the tactile paving will impact on the detectability of the tactile paving. The DfT (2007b) guidance suggests a 150 mm minimum contrasting border where there is insufficient tonal contrast.…”

Tactile paving has been designed in response to the needs of vision-impaired pedestrians to be independent, mobile, confident and safe when using the external environment. Tactile paving is not without its critics because it can adversely affect other pedestrians particularly older people, and those with mobility impairments. Interviews were conducted at eight selected road crossing sites in Edinburgh to determine older people's experiences of using specific road crossings, in particular their views and experiences of using tactile paving. Two hundred participants were interviewed who were aged 65 years and older, and who appeared not to have a significant health issue or disability that was affecting their mobility. In addition, eight pedestrians who had significant mobility issues and 30 pedestrians who had moderate to severe vision impairment were interviewed. Findings demonstrate the importance of training in tactile paving for pedestrians with a vision impairment; the need for a review of the guidance on tactile paving such that greater emphasis is placed on detectability and tonal contrast, and tonal contrast; a consideration as to whether seven types of tactile paving is too many; and the need to minimise the effects of topography, particularly slope at road crossings.

The most important problem experinced by visually impaired individuals is inadequacy of opportunities and inequality of opportunities with other people. The yellow striped pavement was made to help distance-place-direction sense while walking, to meet the needs of constant self-awareness to remove a possible accident situation has a very important place for the visually impaired. Our aim is to investigate the usability of yellow striped pavements applied to Öz Görme engelli bir kişinin yaşadığı en önemli sorun, gözlerinin görmemesi değil; kendisine sağlanan olanakların yetersizliği ve diğer insanlarla arasındaki fırsat eşitsizliğidir. Yürürken mesafe-yer-yön duygusunu kontrol etme, sürekli kendilerini fark ettirme ihtiyaçlarını gidermek ve olası bir kaza durumunu ortadan kaldırmak için yapılan sarı şeritli kaldırımlar, görme engelliler için oldukça önemli bir yere sahiptir.

“…To address this issue, a warning surface is installed at the edge of the ramp to provide a sensible contrast with the adjacent walking area. Different countries, including Sweden, the UK, the U.S.A., and Japan have considered using warning systems that rely on tactile and visual contrast ( 1 , 3 – 5 ). Truncated dome detectable warning surface (DWS) has proved to be easy to detect by most vision-impaired pedestrians either by foot or a cane ( 6 ).…”

Detectable warning surface (DWS) is a panel product installed at the edge of curb ramps to warn visually impaired pedestrians about the proximity of the roadway. Most DWS products are made of polymers and are subjected to outdoor weathering. Therefore, sunlight degradation is an important factor that affects their service life. In this study, the effects of sunlight on material degradation in four DWS products made from polyester, neopentylglycol (NPG), polyurethane, and polyolefin were evaluated by exposing DWS test coupons in a xenon weatherometer. The exposure conditions were largely based on ASTM D 2565 for a duration of 3,000 h. Color change induced by radiation was measured using a spectro-colorimeter. The fastest discoloration was measured in DWS made from polyurethane. The largest color change occurred between 500 and 1,000 h for polyurethane and between 1,000 and 3,000 h for other polymers. The changes of surface appearance observed under a digital microscope were consistent with the discoloration. The reinforcing fibers in DWS products made from polyester and polyurethane were revealed after 3,000 h exposure. Decrease in surface wear resistance was obtained in tested coupons that were exposed to the highest irradiance level. The product made from NPG exhibited the greatest decrease in wear resistance, while that made from polyolefin showed the least change.
