Urban construction zones can be hazardous to people with visual or mobility impairments if the worksite is not adequately protected. People who use canes may not detect warning tape or a series of widely spaced traffic cones. Such practices are not sufficient to enable a blind pedestrian to anticipate a hazard, nor do they provide an edge along which to travel around an obstruction. The PAR barricade is designed to guide individuals with visual and mobility impairments around dangers in construction sites like drop-offs and trenches by providing a clearly defined & safe pathway through the work zone.
