Common Problems Arising in the Installation of Accessible Pedestrian Signals

Evaluate and adjust locator tone volume

Approach the intersection from both directions along the sidewalk and note when the pushbutton locator tone is audible. If there are two pushbutton locator tones at the corner, each should be audible. The pushbutton locator tone should be audible 6 to 12 ft from the pushbutton or at the building line, whichever is closer to the pushbutton.

Approach the corner from the crosswalk and note when the pushbutton locator tone is audible. The pushbutton locator tone should be audible at 6 to 12 ft (or approximately one lane) from the pushbutton.

Listen through several cycles at times when traffic is noisy and at times when traffic is quiet and adjust the locator tone volume as necessary.
