On June 17, 2002, the U.S. Access Board released draft guidelines that were available for public comment until October 28, 2002. These draft guidelines are based on the PROWAAC recommendations, but differ in several areas. Section 1106 addresses accessible pedestrian signals and is reproduced below.
Comments were submitted in writing or at a public meeting held in Portland, Oregon, on October 8, 2002. Comments are available at www.access-board.gov. The Access Board will prepare a proposed rule based on its review of the comments received. The proposed rule will also be made available for public comment.

The duration of the locator tone shall be 0.15 seconds maximum and shall repeat at intervals of one second. The locator tone shall operate during the DON’T WALK and flashing DON’T WALK intervals only and shall be deactivated when the pedestrian signal system is not operative.
2021.3.3 Size and Contrast. Pedestrian pushbuttons shall be a minimum of 2 inches (51 mm) across in one dimension and shall contrast visually with their housing or mounting.
2021.3.4 Optional Features. An extended button press shall be permitted to activate additional features. Buttons that provide additional features shall be marked with three Braille dots forming an equilateral triangle in the center of the pushbutton.
1106.4 Directional Information and Signs. Pedestrian signal devices shall provide tactile and visual signs on the face of the device or its housing or mounting indicating crosswalk direction and the name of the street containing the crosswalk served by the pedestrian signal.
