Abstract
Crossing crosswalks is one of the most dangerous situations for visually impaired persons. Crosswalk entrances are located on the boundary with the roadway and are among the most dangerous areas for visually-impaired persons. Tactile walking surface indicators (TWSIs) are installed on the road to support independent travel for blind and low-vision individuals. We developed an LED block equipped with projections to strengthen the support of the crosswalk entrance. The blind person can sense this block through the soles of the shoes. A low-vision person can find it through the use of residual vision. Blind and visually impaired persons found that the LED block equipped with projections to locate the travel direction effectively supported crossing. The effectiveness of this block is described based on measurements and questionnaire results.
