a flashing "don't walk" pedestrian signal indicates that

Tactile maps of crosswalks may also be provided. 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. The additional time provided by an extended pushbutton press to satisfy pedestrian clearance time needs may be added to either the walk interval or the pedestrian change interval. At those times, the pedestrian signal indications shall not be displayed. 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. Standard: All pedestrian signal heads used at crosswalks where the pedestrian change interval is more than 7 seconds shall include a pedestrian change interval countdown display in order to inform pedestrians of the number of seconds remaining in the pedestrian change interval. The audible walk indication shall be audible from the beginning of the associated crosswalk. Guidance: Traffic Signals WebFlashing Don't Walk or Flashing Raised Hand. Vibrotactile walk indications shall be provided by a tactile arrow on the pushbutton (see. 03 Pedestrian signal heads may be used under other conditions based on engineering judgment. The sound level of audible walk indications and pushbutton locator tones should be adjusted to be low enough to avoid misleading pedestrians who have visual disabilities when the following conditions exist: 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. chapter 14 drivers ed Flashcards | Quizlet 25 Following the audible walk indication, accessible pedestrian signals shall revert to the pushbutton locator tone (see Section 4E.12) during the pedestrian change interval. 05 Local organizations, providing support services to pedestrians who have visual and/or hearing disabilities, can often act as important advisors to the traffic engineer when consideration is being given to the installation of devices to assist such pedestrians. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not 02 An accessible pedestrian pushbutton shall incorporate a locator tone. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not be used. The pedestrian clearance time is intended to allow pedestrians who started crossing during the walk interval to complete their crossing. WebWalk interval, then a flashing Don't Walk interval, followed by a solid Don't Walk interval. At intersections with pedestrian volumes that are so high that drivers have difficulty finding an opportunity to turn across the crosswalk, the duration of the green interval for a parallel concurrent vehicular movement is sometimes intentionally set to extend beyond the pedestrian clearance time to provide turning drivers additional green time to make their turns while the pedestrian signal head is displaying a steady UPRAISED HAND (symbolizing DONT WALK) signal indication after pedestrians have had time to complete their crossings. Option: 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. When a pedestrian activates the crosswalk, the beacons will flash yellow for several seconds. 04 Countdown pedestrian signals shall consist of Portland orange numbers that are at least 6 inches in height on a black opaque background. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. 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 Support: 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. 15 If used, special purpose pushbuttons (to be operated only by authorized persons) should include a housing capable of being locked to prevent access by the general public and do not need an instructional sign. 11 The sound level of audible walk indications and pushbutton locator tones should be adjusted to be low enough to avoid misleading pedestrians who have visual disabilities when the following conditions exist: Option: WebThe walk signal indicates that pedestrians may cross the street, while the dont walk signal indicates that pedestrians must wait. 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. 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. 07 Where two accessible pedestrian signals are separated by a distance of at least 10 feet, the audible walk indication shall be a percussive tone. WebDuring the flashing DON'T WALK phase, the PHB displays alternating flashing red lights to drivers. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. Any additional time that is required to satisfy the conditions of this paragraph should be added to the walk interval. 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. 01 Pedestrian signal head indications shall have the following meanings: 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. They shall begin with the term "Wait," followed by intersection identification information modeled after: "Wait to cross Broadway at Grand." Audible tone walk indications shall repeat at eight to ten ticks per second. Additionally, orientation and mobility specialists or similar staff also might be able to provide a wide range of advice. 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. 03 The WALKING PERSON (symbolizing WALK) signal indication shall be white, conforming to the publication entitled "Pedestrian Traffic Control Signal Indications" (see Section 1A.11), with all except the symbol obscured by an opaque material. The animated eyes symbol shall be at least 12 inches wide with each eye having a width of at least 5 inches and a height of at least 2.5 inches. It need not be repeated for the entire time that the walk interval is not timing. Standard: 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. Transportation The buffer interval shall not begin later than the beginning of the red clearance interval, if used. Accessible pedestrian signals shall have an audible walk indication during the walk interval only. As of May 2018, 73 of Madison's 386 signalized intersections have accessible pedestrian signals. 01 To enable pedestrians who have visual disabilities to distinguish and locate the appropriate pushbutton at an accessible pedestrian signal location, pushbuttons shall clearly indicate by means of tactile arrows which crosswalk signal is actuated by each pushbutton. 05 Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. 22 A speech walk message is not required at times when the walk interval is not timing, but, if provided: 23 If a pilot light (see Section 4E.08) is used at an accessible pedestrian signal location, each actuation shall be accompanied by the speech message "wait. Guidance: An accessible pedestrian pushbutton shall incorporate a locator tone. 07 Except as provided in Paragraph 8, the pedestrian clearance time should be sufficient to allow a pedestrian crossing in the crosswalk who left the curb or shoulder at the end of the WALKING PERSON (symbolizing WALK) signal indication to travel at a walking speed of 3.5 feet per second to at least the far side of the traveled way or to a median of sufficient width for pedestrians to wait. If the pedestrian signal indication is so bright that it causes excessive glare in nighttime conditions, some form of automatic dimming should be used to reduce the brilliance of the signal indication. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. At locations with pretimed traffic control signals or non-actuated approaches, pedestrian pushbuttons may be used to activate the accessible pedestrian signals. Support: 11 Except as provided in Paragraph 12, the walk interval should be at least 7 seconds in length so that pedestrians will have adequate opportunity to leave the curb or shoulder before the pedestrian clearance time begins. 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). Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. 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. Special signal/flashing signal Special signals or flashing signals are used in specific situations, such as school zones, construction zones, and emergency vehicle preemption. Standard: Guidance: These signal indications consist of the illuminated symbols of a WALKING PERSON (symbolizing WALK) and an UPRAISED HAND (symbolizing DONT WALK).
