Other locations where a study indicates audible beaconing would be beneficial. 07 Except as provided in Paragraph 8, where two pedestrian pushbuttons are provided on the same corner of a signalized location, the pushbuttons should be separated by a distance of at least 10 feet. 04 Audible beaconing is the use of an audible signal in such a way that pedestrians with visual disabilities can home in on the signal that is located on the far end of the crosswalk as they cross the street. 19 At intersections with high pedestrian volumes and high conflicting turning vehicle volumes, a brief leading pedestrian interval, during which an advance WALKING PERSON (symbolizing WALK) indication is displayed for the crosswalk while red indications continue to be displayed to parallel through and/or turning traffic, may be used to reduce conflicts between pedestrians and turning vehicles. If no vehicular signal indications are visible to pedestrians, or if the vehicular signal indications that are visible to pedestrians starting a crossing provide insufficient guidance for them to decide when to begin crossing the roadway in the chosen direction, such as on one-way streets, at T-intersections, or at multi-phase signal operations. Standard: The displayed period of each flash shall be a minimum of 1/2 and a maximum of 2/3 of the total flash cycle. Following the pedestrian change interval, a buffer interval consisting of a steady UPRAISED HAND (symbolizing DONT WALK) signal indication shall be displayed for at least 3 seconds prior to the release of any conflicting vehicular movement. Accessible pedestrian signals shall have an audible walk indication during the walk interval only. Tactile arrows shall be located on the pushbutton, have high visual contrast (light on dark or dark on light), and shall be aligned parallel to the direction of travel on the associated crosswalk. 01 Pedestrian signal heads shall be used in conjunction with vehicular traffic control signals under any of the following conditions: Guidance: For pedestrian signal head indications, the symbols shall be at least 6 inches high. 01 Pedestrian detectors may be pushbuttons or passive detection devices. The walk indication is displayed in white, and the don't walk indication is displayed in Portland orange. Countdown displays shall not be used during the walk interval or during the red clearance interval of a concurrent vehicular phase. 02 Passive detection devices register the presence of a pedestrian in a position indicative of a desire to cross, without requiring the pedestrian to push a button. Some passive detection devices are capable of tracking the progress of a pedestrian as the pedestrian crosses the roadway for the purpose of extending or shortening the duration of certain pedestrian timing intervals. Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. If a leading pedestrian interval is used, the use of accessible pedestrian signals (see. WebA permissive turn is made across an opposing flow of through vehicles and/or pedestrians. 17 If speech walk messages are used to communicate the walk interval, they shall provide a clear message that the walk interval is in effect, as well as to which crossing it applies. If information on intersection signalization or geometry is also given, it shall follow the intersection identification information. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not If the pedestrian clearance time is sufficient only to cross from the curb or shoulder to a median of sufficient width for pedestrians to wait and accessible pedestrian detectors are used, an additional accessible pedestrian detector shall be provided in the median. WebPedestrian-control signal indications. The buffer interval shall not begin later than the beginning of the red clearance interval, if used. Support: If a leading pedestrian interval is used without accessible features, pedestrians who are visually impaired can be expected to begin crossing at the onset of the vehicular movement when drivers are not expecting them to begin crossing. 02 Engineering judgment should determine the need for separate pedestrian signal heads (see Section 4D.03) and accessible pedestrian signals (see Section 4E.09). 01 Technology that provides different sounds for each non-concurrent signal phase has frequently been found to provide ambiguous information. At intersections where a diagonal pedestrian crossing is allowed, or where one street receives a WALKING PERSON (symbolizing WALK) signal indication simultaneously with another street. 07 Audible beaconing may be provided in several ways, any of which are initiated by an extended pushbutton press. However, "WAIT" (vs "DON'T WALK") hasn't been used on new pedestrian signals for 30 years, and most instances of "WALK" were replaced with the walking icon (and "DON'T WALK" with the hand signalling "stop") 10-20 years ago. Passive pedestrian detection may also be used to automatically adjust the pedestrian clearance time based on the pedestrian's actual walking speed or actual clearance of the crosswalk. Speech walk messages shall be used only at intersections where it is technically infeasible to install two accessible pedestrian signals at one corner separated by a distance of at least 10 feet. Guidance: At a mounting height of approximately 3.5 feet, but no more than 4 feet, above the sidewalk. 07 Under stop-and-go operation, accessible pedestrian signals shall not be limited in operation by the time of day or day of week. Typically denoted for motorists by a circular green (green ball) signal The driver is "permitted" to cross the opposing through flow, but must select an appropriate gap in the opposing traffic stream through which to turn WebThe "DON'T WALK" indication, steadily illuminated, means that a pedestrian should not enter the street in the direction of the pedestrian signal. Pushbuttons for accessible pedestrian signals should be located in accordance with the provisions of, If two accessible pedestrian pushbuttons are placed less than 10 feet apart or on the same pole, each accessible pedestrian pushbutton shall be provided with the following features (see. Pedestrians may be provided with additional features such as increased crossing time, audible beaconing, or a speech pushbutton information message as a result of an extended pushbutton press. WebFlashing Don't Walk or Flashing Raised Hand. A pushbutton locator tone is a repeating sound that informs approaching pedestrians that a pushbutton to actuate pedestrian timing or receive additional information exists, and that enables pedestrians with visual disabilities to locate the pushbutton. Where two accessible pedestrian signals are separated by a distance of at least 10 feet, the audible walk indication shall be a percussive tone. 20 Speech walk messages shall not contain any additional information, except they shall include designations such as "Street" or "Avenue" where this information is necessary to avoid ambiguity at a particular location. Therefore, it is desirable to give users of accessible pedestrian signals the name of the street controlled by the pushbutton. If you have entered the Standard: WebDuring the flashing DON'T WALK phase, the PHB displays alternating flashing red lights to drivers. 11 At certain locations, a supplemental sign in a more visible location may be used to call attention to the pedestrian pushbutton. 14 The total of the walk interval and pedestrian clearance time should be sufficient to allow a pedestrian crossing in the crosswalk who left the pedestrian detector (or, if no pedestrian detector is present, a location 6 feet from the face of the curb or from the edge of the pavement) at the beginning of the WALKING PERSON (symbolizing WALK) signal indication to travel at a walking speed of 3 feet per second to the far side of the traveled way being crossed or to the median if a two-stage pedestrian crossing sequence is used. 02 If an extended pushbutton press is used to provide any additional feature(s), a pushbutton press of less than one second shall actuate only the pedestrian timing and any associated accessible walk indication, and a pushbutton press of one second or more shall actuate the pedestrian timing, any associated accessible walk indication, and any additional feature(s). 08 A walking speed of up to 4 feet per second may be used to evaluate the sufficiency of the pedestrian clearance time at locations where an extended pushbutton press function has been installed to provide slower pedestrians an opportunity to request and receive a longer pedestrian clearance time. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. When used, accessible pedestrian signals shall be used in combination with pedestrian signal timing. The existing environment is often not sufficient to provide the information that pedestrians who have visual disabilities need to cross a roadway at a signalized location. Countdown pedestrian signals shall consist of Portland orange numbers that are at least 6 inches in height on a black opaque background. Option: 06 If the pedestrian signal rests in walk, the accessible walk indication should be limited to the first 7 seconds of the walk interval. If used with a pedestrian signal head that does not have a concurrent vehicular phase, the pedestrian clearance interval (flashing UPRAISED HAND) should be set to be approximately 4 seconds less than the required pedestrian crossing time (see. Research indicates that a rapid tick tone for each crossing coming from accessible pedestrian signal devices on separated poles located close to each crosswalk provides unambiguous information to pedestrians who are blind or visually impaired. Issued by FHWA. 24 Accessible pedestrian signals that provide speech walk messages may provide similar messages in languages other than English, if needed, except for the terms "walk sign" and "wait.". After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. ", 19 Speech walk messages that are used at intersections having exclusive pedestrian phasing shall be patterned after the model: "Walk sign is on for all crossings.". WebPedestrian signal indicators consist of symbols displaying a person walking for "WALK" displayed in white, and a hand for "DON'T WALK" displayed in orange. By combining the information from the pushbutton message or Braille label, the tactile arrow aligned in the direction of travel on the relevant crosswalk, and the speech walk message, pedestrians with visual disabilities are able to correctly respond to speech walk messages even if there are two pushbuttons on the same pole. Option: 16 If used, a pilot light or other means of indication installed with a pedestrian pushbutton shall not be illuminated until actuation. The audible walk indication shall be audible from the beginning of the associated crosswalk. Pedestrians who are currently crossing may continue across the road. Standard Highway Signs and Markings (SHSM) BookDesign Details, Interpretations These provisions also position pushbutton poles in optimal locations for installation of accessible pedestrian signals (see, If pedestrian pushbuttons are used, they should be capable of easy activation and conveniently located near each end of the crosswalks. Support: All new pedestrian signal head indications shall be displayed within a rectangular background and shall consist of symbolized messages (see. The WALK or WALKING PERSON appears when it is legal to start crossing. When the DON'T WALK or RAISED HAND appears, you may not start across the street. The flashing signal means you should not begin to cross because you may not have enough time to make it to the other side before vehicles start moving across your path. 3. 18 Speech walk messages that are used at intersections having pedestrian phasing that is concurrent with vehicular phasing shall be patterned after the model: "Broadway. These signal indications consist of the illuminated symbols of a WALKING PERSON (symbolizing WALK) and an UPRAISED HAND (symbolizing DONT WALK). 12 If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. Option: Speech messages might be either directly audible or transmitted, requiring a personal receiver to hear the message. Pedestrian signal head indications shall have the following meanings: Pedestrian signal heads shall be used in conjunction with vehicular traffic control signals under any of the following conditions: Pedestrian signal heads should be used under any of the following conditions: Pedestrian signal heads may be used under other conditions based on engineering judgment. Speech walk messages should not tell pedestrians that it is "safe to cross," because it is always the pedestrian's responsibility to check actual traffic conditions. Where the pedestrian clearance time is sufficient only for crossing from the curb or shoulder to a median of sufficient width for pedestrians to wait, median-mounted pedestrian signals (with pedestrian detectors if actuated operation is used) shall be provided (see, Where median-mounted pedestrian signals and detectors are provided, the use of accessible pedestrian signals (see, During the transition into preemption, the walk interval and the pedestrian change interval may be shortened or omitted as described in. The countdown pedestrian signal shall be located immediately adjacent to the associated UPRAISED HAND (symbolizing DONT WALK) pedestrian signal head indication (see Figure 4E-1). 03 The provisions in this Section place pedestrian pushbuttons within easy reach of pedestrians who are intending to cross each crosswalk and make it obvious which pushbutton is associated with each crosswalk. After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. At those times, the pedestrian signal indications shall not be displayed. Vibrotactile indications provide information to pedestrians who are blind and deaf and are also used by pedestrians who are blind or who have low vision to confirm the walk signal in noisy situations. For crosswalks where the pedestrian enters the crosswalk more than 100 feet from the pedestrian signal head indications, the symbols should be at least 9 inches high. WebThe flashing Don't Walk indicates to pedestrians that there is sufficient time to complete walking across the street, but not enough time if they have not yet begun to cross. If it is necessary to assist pedestrians in deciding when to begin crossing the roadway in the chosen direction or if engineering judgment determines that pedestrian signal heads are justified to minimize vehicle-pedestrian conflicts; If pedestrians are permitted to cross a portion of a street, such as to or from a median of sufficient width for pedestrians to wait, during a particular interval but are not permitted to cross the remainder of the street during any part of the same interval; and/or. 08 If audible beaconing is used, the volume of the pushbutton locator tone during the pedestrian change interval of the called pedestrian phase shall be increased and operated in one of the following ways: Option: 23 If a leading pedestrian interval is used, consideration should be given to prohibiting turns across the crosswalk during the leading pedestrian interval. 03 If a particular signalized location presents difficulties for pedestrians who have visual disabilities to cross the roadway, an engineering study should be conducted that considers the needs of pedestrians in general, as well as the information needs of pedestrians with visual disabilities. The pedestrian clearance time is intended to allow pedestrians who started crossing during the walk interval to complete their crossing. 11 The name of the street to be crossed may also be provided in accessible format, such as Braille or raised print. Option: Support: 04 Accessible pedestrian signals shall have an audible walk indication during the walk interval only. 10 If the pedestrian change interval is interrupted or shortened as a part of a transition into a preemption sequence (see Section 4E.06), the countdown pedestrian signal display should be discontinued and go dark immediately upon activation of the preemption transition. you should prepare to The existing environment is often not sufficient to provide the information that pedestrians who have visual disabilities need to cross a roadway at a signalized location.
