Cities are using leading pedestrian signalization (LLI) technology to give pedestrians on foot more time to cross intersections safely. However, blind and visually impaired pedestrians, who cannot read the visual LPI sign, learn to safely cross the street by reading the flow of traffic audibly by the sound of the parallel traffic surge. Therefore, if an accessible pedestrian signal (APS) is not installed at intersections with LPI technology, blind and visually impaired pedestrians wait at the curb listening for the traffic to change while other sighted pedestrians begin to cross the intersection. This lessens the amount of time that such persons have to cross the intersection. Studies have shown that close to thirty percent of blind and visually impaired pedestrians do not make it across the street before the light turns. Consequently, it is imperative that LPI technology is paired with an APS.
