Design example provided to participants below:
Below are drawings of people using a pedestrian traffic signal at an intersection. There is a 3 inch round push plate that changes the traffic signal to permit pedestrians to cross the road. The push plate is 36 inches above ground and is labeled with the street's name in both raised letters and Braille. When the pedestrian traffic signal is activated, visual and audible countdowns start to let pedestrians know how long they have to wait and how long they have to cross.
