Module G - Slide 4


The new features of APS may be confusing to those who have never experienced this type of APS device. You may wish to provide information about the pushbutton locator tone, specifically that it repeats once per second and is not a WALK indication. Some people have thought the signals were malfunctioning because they heard the sound constantly. Also some people may not be aware that it’s necessary to push a button to get the WALK signal/sound. Another aspect that needs explanation is that the volume of the pushbutton locator tone and the WALK indication may change in response to traffic noise, and that a change in volume is not an indication of the time to cross.

In the research for this project, it was also noted that individuals who are blind may need instruction in how to use the tactile arrow and how to distinguish which direction the arrow is pointing.
