02 Accessible pedestrian signals shall have both audible and vibrotactile walk indications. Guidance: Where there are physical constraints that make it impractical to place the pedestrian pushbutton adjacent to a level all-weather surface, the surface should be as level as feasible. 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.". 02 The primary technique that pedestrians who have visual disabilities use to cross streets at signalized locations is to initiate their crossing when they hear the traffic in front of them stop and the traffic alongside them begin to move, which often corresponds to the onset of the green interval. The accessible walk indication should be recalled by a button press during the walk interval provided that the crossing time remaining is greater than the pedestrian change interval. 03 Pedestrian signal heads may be used under other conditions based on engineering judgment. If you have already started to cross, finish crossing the 01 Pedestrian signal heads provide special types of traffic signal indications exclusively intended for controlling pedestrian traffic. WebPedestrian signals are special types of traffic-signal indications installed for the exclusive purpose of controlling pedestrian traffic. 01 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. The engineering study should consider the following factors: The factors that make crossing at a signalized location difficult for pedestrians who have visual disabilities include: increasingly quiet cars, right turn on red (which masks the beginning of the through phase), continuous right-turn movements, complex signal operations, traffic circles, and wide streets. A steady UPRAISED HAND (symbolizing DONT WALK) signal indication means that a pedestrian shall not enter the roadway in the direction of the signal indication. This requirement shall not apply to traffic control signals or pedestrian hybrid beacons that are activated from a flashing or dark mode to a stop-and-go mode by pedestrian actuations. A steady UPRAISED HAND (symbolizing DONT WALK) signal indication means that a pedestrian shall not enter the roadway in the direction of the signal indication. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not be used. The walk indication is displayed in white, and the don't walk indication is displayed in Portland orange. 12 An alert tone, which is a very brief burst of high-frequency sound at the beginning of the audible walk indication that rapidly decays to the frequency of the walk tone, may be used to alert pedestrians to the beginning of the walk interval. 02 Pedestrian signal heads used at crosswalks where the pedestrian change interval is 7 seconds or less may include a pedestrian change interval countdown display in order to inform pedestrians of the number of seconds remaining in the pedestrian change interval. Except as provided in Paragraphs 5 and 6, pedestrian pushbuttons should be located to meet all of the following criteria (see Figure 4E-3): 05 Where there are physical constraints that make it impractical to place the pedestrian pushbutton adjacent to a level all-weather surface, the surface should be as level as feasible. 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: Speech pushbutton information messages may provide intersection identification, as well as information about unusual intersection signalization and geometry, such as notification regarding exclusive pedestrian phasing, leading pedestrian intervals, split phasing, diagonal crosswalks, and medians or islands. 13 The walk interval is intended for pedestrians to start their crossing. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. 05 Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. Standard: Standard: If information on intersection signalization or geometry is also given, it shall follow the intersection identification information. When the pedestrian signal heads associated with a crosswalk are displaying either a steady WALKING PERSON (symbolizing WALK) or a flashing UPRAISED HAND (symbolizing DONT WALK) signal indication, a steady or a flashing red signal indication shall be shown to any conflicting vehicular movement that is approaching the intersection or midblock location perpendicular or nearly perpendicular to the crosswalk. WebFlashing Don't Walk or Flashing Raised Hand. Where there are physical constraints that make it impractical to place the pedestrian pushbutton between 1.5 and 6 feet from the edge of the curb, shoulder, or pavement, it should not be farther than 10 feet from the edge of curb, shoulder, or pavement. 01 At intersections equipped with pedestrian signal heads, the pedestrian signal indications shall be displayed except when the vehicular traffic control signal is being operated in the flashing mode. The volume of audible walk indications and pushbutton locator tones (see. 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. 14 The use of additional pedestrian detectors on islands or medians where a pedestrian might become stranded should be considered. 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. They shall begin with the term "Wait," followed by intersection identification information modeled after: "Wait to cross Broadway at Grand." If you have entered the Option: Pedestrian signal heads provide special types of traffic signal indications exclusively intended for controlling pedestrian traffic. A flashing WALK signal indicates that the pedestrian crossing phase is nearing completion and a DONT WALK sign will soon be displayed. WebThe pedestrian phase consists of three intervals: walk; pedestrian clearance, commonly referred to as flashing dont walk (FDW); and solid dont walk. The pedestrian shall yield the right-of-way to vehicles lawfully within the intersection at the time that the WALKING PERSON (symbolizing WALK) signal indication is first shown. If a two-section pedestrian signal head is used, the UPRAISED HAND (symbolizing DONT WALK) signal section shall be mounted directly above the WALKING PERSON (symbolizing WALK) signal section. This requirement shall not apply to traffic control signals or pedestrian hybrid beacons that are activated from a flashing or dark mode to a stop-and-go mode by pedestrian actuations. Therefore, it is desirable to give users of accessible pedestrian signals the name of the street controlled by the pushbutton. If a leading pedestrian interval is used, consideration should be given to prohibiting turns across the crosswalk during the leading pedestrian interval. If pedestrian signal heads are mounted on the same support as vehicular signal heads, there shall be a physical separation between them. 07 Section 4E.11 contains additional provisions regarding the volume and sound level of pushbutton locator tones. Option: 17 Where median-mounted pedestrian signals and detectors are provided, the use of accessible pedestrian signals (see Sections 4E.09 through 4E.13) should be considered. When pedestrian signal heads are used, a WALKING PERSON (symbolizing WALK) signal indication shall be displayed only when pedestrians are permitted to leave the curb or shoulder. Support: Where engineering judgment determines that multi-phase signal indications (as with split-phase timing) would tend to confuse or cause conflicts with pedestrians using a crosswalk guided only by vehicular signal indications. The primary technique that pedestrians who have visual disabilities use to cross streets at signalized locations is to initiate their crossing when they hear the traffic in front of them stop and the traffic alongside them begin to move, which often corresponds to the onset of the green interval. WebThe flashing orange Upraised Hand symbol or "DON'T WALK" signal, really means "Don't Start," and if you have stepped into the street during the WALK interval, there The sum of the time of the pedestrian change interval and the buffer interval shall not be less than the calculated pedestrian clearance time (see Paragraphs 7 through 16). 20 If a leading pedestrian interval is used, the use of accessible pedestrian signals (see Sections 4E.09 through 4E.13) should be considered. The information provided by an accessible pedestrian signal shall clearly indicate which pedestrian crossing is served by each device. no pedestrian will cross the street. Whenever pedestrian control signals exhibiting the words, numbers, or symbols meaning "Walk" or "Don't Walk" are in place such signals shall indicate and apply to pedestrians as follows: Walk. An alert tone can be particularly useful if the walk tone is not easily audible in some traffic conditions. 22 If a leading pedestrian interval is used, it should be at least 3 seconds in duration and should be timed to allow pedestrians to cross at least one lane of traffic or, in the case of a large corner radius, to travel far enough for pedestrians to establish their position ahead of the turning traffic before the turning traffic is released. To be a useful system, the words and their meaning need to be correctly understood by all users in the context of the street environment where they are used. Option: 11 Speech pushbutton information messages should not be used to provide landmark information or to inform pedestrians with visual disabilities about detours or temporary traffic control situations. If additional crossing time is provided by means of an extended pushbutton press, a PUSH BUTTON FOR 2 SECONDS FOR EXTRA CROSSING TIME (R10-32P) plaque (see. 06 The countdown pedestrian signal shall display the number of seconds remaining until the termination of the pedestrian change interval (flashing UPRAISED HAND). 07 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 Section 4E.06) and an additional clearance interval (during which a steady UPRAISED HAND is displayed) should be provided prior to the start of the conflicting vehicular phase. 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. Support: Audible beaconing should only be considered following an engineering study at: Audible beaconing may be provided in several ways, any of which are initiated by an extended pushbutton press. Speech walk messages communicate to pedestrians which street has the walk interval. 09 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. Longer walk intervals are often used when the duration of the vehicular green phase associated with the pedestrian crossing is long enough to allow it. Standard: As of May 2018, 73 of Madison's 386 signalized intersections have accessible pedestrian signals. The louder audible walk indication and louder locator tone comes from the far end of the crosswalk, as pedestrians cross the street, The louder locator tone comes from both ends of the crosswalk, or. At a mounting height of approximately 3.5 feet, but no more than 4 feet, above the sidewalk. Additionally, orientation and mobility specialists or similar staff also might be able to provide a wide range of advice. WebA steady UPRAISED HAND (symbolizing DONT WALK) signal indication means that a pedestrian shall not enter the roadway in the direction of the signal indication. Guidance: If speech pushbutton information messages are made available by actuating the accessible pedestrian signal detector, they shall only be actuated when the walk interval is not timing. Other locations where a study indicates audible beaconing would be beneficial. At locations with pretimed traffic control signals or non-actuated approaches, pedestrian pushbuttons may be used to activate the accessible pedestrian signals. 19 If additional crossing time is provided by means of an extended pushbutton press, a PUSH BUTTON FOR 2 SECONDS FOR EXTRA CROSSING TIME (R10-32P) plaque (see Figure 2B-26) shall be mounted adjacent to or integral with the pedestrian pushbutton. Audible tones used as walk indications shall consist of multiple frequencies with a dominant component at 880 Hz. This can be done by means of a speech pushbutton information message (see Section 4D.13) during the flashing or steady UPRAISED HAND intervals, or by raised print and Braille labels on the pushbutton housing. To be a useful system, the words and their meaning need to be correctly understood by all users in the context of the street environment where they are used. 06 If the pedestrian signal rests in walk, the accessible walk indication should be limited to the first 7 seconds of the walk interval. Option: Pedestrians who are currently crossing may continue across the road. 02 If a two-section pedestrian signal head is used, the UPRAISED HAND (symbolizing DONT WALK) signal section shall be mounted directly above the WALKING PERSON (symbolizing WALK) signal section. Tactile maps of crosswalks may also be provided. 16 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 Sections 4E.08 and 4E.09) and signing such as the R10-3d sign (see Section 2B.52) shall be provided to notify pedestrians to cross only to the median to await the next WALKING PERSON (symbolizing WALK) signal indication. If the pedestrian signal rests in walk, the accessible walk indication should be limited to the first 7 seconds of the walk interval. 10 Accessible pedestrian signals are typically integrated into the pedestrian detector (pushbutton), so the audible tones and/or messages come from the pushbutton housing. 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 accessible walk indication should be recalled by a button press during the walk interval provided that the crossing time remaining is greater than the pedestrian change interval. The U.S. Access Board (www.access-board.gov) provides technical assistance for making pedestrian signal information available to persons with visual disabilities (see Page i for the address for the U.S. Access Board). 04 The factors that make crossing at a signalized location difficult for pedestrians who have visual disabilities include: increasingly quiet cars, right turn on red (which masks the beginning of the through phase), continuous right-turn movements, complex signal operations, traffic circles, and wide streets. 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. 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. 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. Support: 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. Support: During the yellow change interval, the UPRAISED HAND (symbolizing DON'T WALK) signal indication may be displayed as either a flashing indication, a steady indication, or a flashing indication for an initial portion of the yellow change interval and a steady indication for the remainder of the interval. Any additional time that is required to satisfy the conditions of this paragraph should be added to the walk interval. 13 At accessible pedestrian signal locations where pedestrian pushbuttons are used, each pushbutton shall activate both the walk interval and the accessible pedestrian signals. In getting directions to travel to a new location, pedestrians with visual disabilities do not always get the name of each street to be crossed. For crosswalks where the pedestrian enters the crosswalk more than 100 feet from the countdown pedestrian signal display, the numbers should be at least 9 inches in height. 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. Accessible pedestrian signals are typically integrated into the pedestrian detector (pushbutton), so the audible tones and/or messages come from the pushbutton housing. 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: Audible tone walk indications shall repeat at eight to ten ticks per second. 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. 13 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 the signals are pedestrian actuated, an additional pedestrian detector shall be provided in the median. The signal for pedestrians to walk is a white walking symbol. WebA flashing "DON'T WALK" pedestrian signal indicates that: A. the signal light will soon be yellow B. no pedestrian will cross the street C. you should prepare to slow D. your Standard: Standard Highway Signs and Markings (SHSM) BookDesign Details, Interpretations 12 If used, the animated eyes symbol shall consist of an outline of a pair of white steadily-illuminated eyes with white eyeballs that scan from side to side at a rate of approximately once per second. Another feature, which the City recently added at some intersections, is a "countdown" timer which coincides with the flashing "DON'T WALK." If used, a pilot light or other means of indication installed with a pedestrian pushbutton shall not be illuminated until actuation. Option: Whenever pedestrians are controlled by pedestrian- control signals exhibiting the words WALK or DONT WALK, or exhibiting symbols of a walking person or upraised hand, such signals shall indicate and apply to pedestrians as follows: (a) Steady WALK or walking person. Where countdown pedestrian signals are used, the countdown shall always be displayed simultaneously with the flashing UPRAISED HAND (symbolizing DONT WALK) signal indication displayed for that crosswalk. 03 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 on one corner are not separated by a distance of at least 10 feet, the audible walk indication shall be a speech walk message. Each pedestrian signal head indication shall be independently displayed and emit a single color. 01 Pedestrian signal head indications shall have the following meanings: Standard: WebPedestrian signals consist of walk and don't walk signals or the international symbols displaying a person walking for the walk indication, and a hand for the don't walk indication. 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. When not illuminated, the WALKING PERSON (symbolizing WALK) and UPRAISED HAND (symbolizing DONT WALK) symbols shall not be readily visible to pedestrians at the far end of the crosswalk that the pedestrian signal head indications control. Accessible pedestrian signals and detectors provide information in non-visual formats (such as audible tones, speech messages, and/or vibrating surfaces). 18 During the transition into preemption, the walk interval and the pedestrian change interval may be shortened or omitted as described in Section 4D.27. If a one-section pedestrian signal head is used, the symbols shall be either overlaid upon each other or arranged side-by-side with the UPRAISED HAND symbol to the left of the WALKING PERSON symbol, and a light source that can display each symbol independently shall be used. On a street with a median of sufficient width for pedestrians to wait, a pedestrian clearance time that allows the pedestrian to cross only from the curb or shoulder to the median may be provided. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. Additionally, orientation and mobility specialists or similar staff also might be able to provide a wide range of advice. Standard: Guidance: 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. The engineering study should consider the following factors: Support: 04 Accessible pedestrian signals shall have an audible walk indication during the walk interval only. Crosswalks longer than 70 feet, unless they are divided by a median that has another accessible pedestrian signal with a locator tone; Intersections with irregular geometry, such as more than four legs; Crosswalks where audible beaconing is requested by an individual with visual disabilities; or. Standard: 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 the signals are pedestrian actuated, an additional pedestrian detector shall be provided in the median. 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. Special signal/flashing signal Special signals or flashing signals are used in specific situations, such as school zones, construction zones, and emergency vehicle preemption. 23 If a leading pedestrian interval is used, consideration should be given to prohibiting turns across the crosswalk during the leading pedestrian interval. 04 A pedestrian change interval consisting of a flashing UPRAISED HAND (symbolizing DONT WALK) signal indication shall begin immediately following the WALKING PERSON (symbolizing WALK) signal indication. WebWhenever pedestrian control signals exhibiting the words "Walk" or the walking person symbol or "Don't Walk" or the hand symbol are operating, the signals shall indicate as It need not be repeated for the entire time that the walk interval is not timing. Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. At accessible pedestrian signal locations where pedestrian pushbuttons are used, each pushbutton shall activate both the walk interval and the accessible pedestrian signals.
