Module F - Slide 22
When adjusting the sound settings, it’s important to realize that signals that are too loud are a common problem. When the APS locator tone and walk indication is too loud, it prevents the pedestrian from:
- Hearing critical traffic sounds for alignment
- Determining that cars have stopped
- Hearing cars that may be turning across their path
- Localizing on the signal source
The APS sounds are not intended to be heard all the way across the street, unless audible beaconing is installed at that location. Audible beaconing may be used for locations of skewed crosswalks, and where the street is very wide, but would only be called “on request” by an extended button press.
