Draft guidelines Draft Public Rights-of-Way Accessibility Guidelines were
published on June 17, 2002. While the guidelines have not been published
as a final rule, they provide the most comprehensive guidance available
at this time.
The Draft Guidelines for new construction and reconstruction
require the following:
APS devices integral with the pushbutton
Audible and vibrotactile indications of the Walk interval
WALK indication by tone or voice (speech)
Pushbutton locator tone where there are pushbuttons
Tactile and visual signs on the face of the device or its housing
Signs are to include a tactile arrow indicating the crosswalk direction
and the name of the street.
The Draft Guidelines state that an extended button press shall
be permitted to activate additional features. However, no information is
provided which specifies what those features may include.
PROWAAC recommended the following possible responses to an extended button
"sound beaconing by increasing the volume of the WALK tone and the
associated locator tone for one signal cycle, so a blind pedestrian
might be able to use the sound from the opposite side of the street
to provide alignment information;
sound beaconing by alternating the audible WALK signal back and
forth from one end of the crosswalk to the other;
providing extended crossing time; and
providing a voice message with the street names at the intersection."
