R307 — Pedestrian Push Buttons and Passive Pedestrian Detection
R307.1 General. Pedestrian push buttons and passive pedestrian detection devices shall comply with R307. Operable parts of pedestrian push buttons shall comply with R403. R307.2 Activation. Pedestrian push buttons and passive detection devices shall activate the accessible pedestrian signals and, where applicable, the walk interval. R307.3 Extended Push Button Press. Where an extended push button press is used to provide any additional features, a push button press of less than one second shall actuate only the pedestrian timing and any associated accessible walk indication, and a push button press of one second or more shall actuate the pedestrian timing, any associated accessible walk indication, and any additional features. If additional crossing time is provided by means of an extended pushbutton press, a sign so indicating shall be mounted adjacent to or integral with the pedestrian push button. R307.4 Location. Pedestrian push buttons shall be located no greater than 5 feet from the side of a curb ramp run or the edge of the farthest associated crosswalk line from the center of the intersection. Pedestrian push buttons shall be located between 1.5 and 10 feet from the edge of the curb or pavement. R307.4.1 Two Pedestrian Push Buttons on Same Corner. Where two pedestrian push buttons are provided on the same corner, they shall be 10 feet or more apart. Exception: In alterations, where technically infeasible to provide 10 feet separation between pedestrian push buttons on the same corner, a pedestrian push button information message complying with R308.3.2 shall be provided. R307.5 Push Button Orientation. The face of the push button shall be parallel to its associated crosswalk. R307.6 Audible and Vibrotactile Walk Indications for Pedestrian Signal Heads. Pedestrian push buttons or passive detection devices shall activate audible and vibrotactile walk indications complying with R308. R307.7 Audible and Vibrotactile Indication for Pedestrian Activated Warning Devices Without a Walk Indication. Where a pedestrian push button or a passive detection device is provided for pedestrian activated warning devices, such as rectangular rapid flashing beacons, the pedestrian push button or passive detection device shall activate a speech message that indicates the status of the beacon in lieu of an audible walk indication. The speech message volume shall comply with R308.4. Where a pedestrian push button is provided, it shall not include vibrotactile features indicating a walk interval. R307.8 Locator Tone. Pedestrian push buttons shall incorporate a locator tone complying with R307.8. R307.8.1 Duration. Locator tones shall have a duration of 0.15 seconds or less and repeat at one-second intervals except when another audible indication from the same device is active. When another audible indication from the same device is active, the locator tone shall be silenced. Exception: A locator tone may be silenced if a passive detection system activates the locator tone when a pedestrian is within a 12-foot radius of the pedestrian push button. R307.8.2 Locator Tone in Response to Ambient Sound. Pedestrian push button locator tones shall be intensity responsive to ambient sound and shall be audible 6 to 12 feet from the push button, or to the building line, whichever is less. The push button locator tone shall be louder than ambient sound up to a maximum volume of 5 dBA louder than ambient sound. Automatic volume adjustment in response to ambient traffic sound level shall be a maximum volume of 100 dBA. R307.8.3 Locator Tone and Audible Beaconing. Where audible beaconing is used, the volume of the push button locator tone during the pedestrian change interval of the called pedestrian phase shall be increased and operated in one of the following ways: A. The louder audible walk indication and louder locator tone comes from the far end of the crosswalk, as pedestrians cross the street; B. The louder locator tone comes from both ends of the crosswalk; or C. The louder locator tone comes from an additional speaker that is aimed at the center of the crosswalk and that is mounted on a pedestrian signal head. R307.8.4 Locator Tone and Traffic Control Signal in Flashing Mode. When the traffic control signal is operating in a flashing mode, pedestrian push button locator tones shall remain active, and the pedestrian push button shall activate a speech message that communicates the operating mode of the traffic control signal. Where traffic control signals or pedestrian hybrid beacons are activated from a flashing or dark mode to a stop-and-go mode by pedestrian actuations, a speech message communicating the operating status of the traffic control signal is not required. R307.9 Tactile Arrow. Pedestrian push buttons shall have a tactile arrow with high visual contrast that is aligned parallel to the direction of travel on their associated crosswalks.
