Common Problems Arising in the Installation of Accessible Pedestrian Signals

Vibrotactile WALK indications

Vibrotactile indications are transmitted by a vibrating plate or arrow on the housing of the pedestrian pushbutton. During WALK, the arrow or plate vibrates. Thus, a pedestrian must be able to stand with a hand on the device while he/she is aligned and waiting to begin crossing. The vibrotactile indication is particularly useful for pedestrians who have both hearing and visual impairments and also allows pedestrians to tactually confirm audible signal information in noisy environments.
