Performance Evaluation of a Crossing-Assistance System for Visually Disabled Persons at Intersections Considering Actual Road Structure

This paper evaluates, through outdoor experiments and a questionnaire, the performance of a crossing-assistance system for visually disabled persons at signalized intersections by utilizing pedestrian traffic signals in concert with visible light communication (VLC) technology. From the results of the survey, it is found that the guidance given by the VLC system enables the visually disabled to cross safely at signalized intersections, under actual road conditions. The applicability of the system is highly evaluated.
