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. When a pedestrian is detected, the pedestrian signal should be activated and the total phase length (WALK and FLASHING DONT WALK) should be based on Guidance: Where there is an island that allows unsignalized right turns across a crosswalk between the island and the sidewalk. 14 The use of additional pedestrian detectors on islands or medians where a pedestrian might become stranded should be considered. If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. The countdown pedestrian signal shall be located immediately adjacent to the associated UPRAISED HAND (symbolizing DONT WALK) pedestrian signal head indication (see. WebPedestrian-control signal indications. 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. 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. 03 Pedestrian signal heads may be used under other conditions based on engineering judgment. WebThe pedestrian clearance interval consists of a flashing "Don't Walk" signal. 08 Audible tone walk indications shall repeat at eight to ten ticks per second. Speech walk messages should not state or imply a command to the pedestrian, such as "Cross Broadway now." 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. Section 4E.03 Application of Pedestrian Signal Heads Standard: Issued by FHWA. Standard: 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. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. 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. 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. Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. 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 you have entered the Engineering judgment should determine the need for separate pedestrian signal heads (see. Standard: 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. Pedestrian signal heads shall be mounted with the bottom of the signal housing including brackets not less than 7 feet or more than 10 feet above sidewalk level, and shall be positioned and adjusted to provide maximum visibility at the beginning of the controlled crosswalk. 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. A steady WALKING PERSON (symbolizing WALK) signal indication means that a pedestrian facing the signal indication is permitted to start to cross the roadway in the direction of the signal indication, possibly in conflict with turning vehicles. The signal for pedestrians to walk is a white walking symbol. 09 Because some technology includes the countdown pedestrian signal logic in a separate timing device that is independent of the timing in the traffic signal controller, care should be exercised by the engineer when timing changes are made to pedestrian change intervals. 16 If used, a pilot light or other means of indication installed with a pedestrian pushbutton shall not be illuminated until actuation. 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. 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. A pedestrian The WALKING PERSON (symbolizing WALK) signal indication shall be white, conforming to the publication entitled "Pedestrian Traffic Control Signal Indications" (see, The UPRAISED HAND (symbolizing DONT WALK) signal indication shall be Portland orange, conforming to the publication entitled "Pedestrian Traffic Control Signal Indications" (see. 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. Option: Option: These signal indications consist of the illuminated symbols of a WALKING PERSON (symbolizing WALK) and an UPRAISED HAND (symbolizing DONT WALK). 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. Support: Special signal/flashing signal Special signals or flashing signals are used in specific situations, such as school zones, construction zones, and emergency vehicle preemption. 2 Flashing yellow lights. 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. Guidance: 05 Not all crosswalks at an intersection need audible beaconing; audible beaconing can actually cause confusion if used at all crosswalks at some intersections. 06 Figure 4E-2 illustrates the pedestrian intervals and their possible relationships with associated vehicular signal phase intervals. 12 Specifications regarding the use of Braille or raised print for traffic control devices can be found in the "Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities (ADAAG)" (see Section 1A.11). WebFlashing Don't Walk or Flashing Raised Hand. Additionally, orientation and mobility specialists or similar staff also might be able to provide a wide range of advice. Other locations where a study indicates audible beaconing would be beneficial. Option: Standard: 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. 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. 10 Where pedestrians who walk slower than 3.5 feet per second, or pedestrians who use wheelchairs, routinely use the crosswalk, a walking speed of less than 3.5 feet per second should be considered in determining the pedestrian clearance time. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. The design requirements for a The Manual on Uniform Traffic Control Devices (MUTCD) recommends the following for 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. Standard: Web1) you're just learning to drive 2) a tailgating driver has closed your rear zone 3) you're approaching a line of sight restriction 4) traction is low 5) you're carrying a heavy load 6) 03 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. Q&A: Be Healthy, Walk Safely How do I maintain my physical independence? Any additional time that is required to satisfy the conditions of this paragraph should be added to the walk interval. 08 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. WebThe pedestrian phase consists of three intervals: walk; pedestrian clearance, commonly referred to as flashing dont walk (FDW); and solid dont walk. Accessible pedestrian signals shall have an audible walk indication during the walk interval only. Accessible pedestrian signals are typically integrated into the pedestrian detector (pushbutton), so the audible tones and/or messages come from the pushbutton housing. Standard: 08 Where there are physical constraints on a particular corner that make it impractical to provide the 10-foot separation between the two pedestrian pushbuttons, the pushbuttons may be placed closer together or on the same pole. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. Where there are physical constraints on a particular corner that make it impractical to provide the 10-foot separation between the two pedestrian pushbuttons, the pushbuttons may be placed closer together or on the same pole. ", Following the audible walk indication, accessible pedestrian signals shall revert to the pushbutton locator tone (see. Guidance: 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. 01 Pedestrian detectors may be pushbuttons or passive detection devices. The clearance interval is based on the street width divided by 4 feet per second walking time. Where two accessible pedestrian signals are separated by a distance of at least 10 feet, the audible walk indication shall be a percussive tone. 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. The audible walk indication shall be audible from the beginning of the associated crosswalk. They shall begin with the term "Wait," followed by intersection identification information modeled after: "Wait to cross Broadway at Grand." 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. Audible tone walk indications shall repeat at eight to ten ticks per second. Youwill alwayshave enough time to finish crossing.Ifyouhavenot startedcrossing, wait until the next WALK signal becauseyou may not have enough time to cross. Do not start Standard: Guidance: 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. 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. 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. 12 If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. Guidance: 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. The display of the number of remaining seconds shall begin only at the beginning of the pedestrian change interval (flashing UPRAISED HAND). 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 Under stop-and-go operation, accessible pedestrian signals shall not be limited in operation by the time of day or day of week. When a pedestrian activates the crosswalk, the beacons will flash yellow for several seconds. 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. Therefore, it is desirable to give users of accessible pedestrian signals the name of the street controlled by the pushbutton. 17 If a pilot light is used at an accessible pedestrian signal location (see Sections 4E.09 through 4E.13), each actuation shall be accompanied by the speech message "wait.". This can be done by means of a speech pushbutton information message (see. 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. 09 Figure 4E-4 shows typical pedestrian pushbutton locations for a variety of situations. All new pedestrian signal head indications shall be displayed within a rectangular background and shall consist of symbolized messages (see. 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). Standard: 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. Standard: If speech walk messages are used, pedestrians have to know the names of the streets that they are crossing in order for the speech walk messages to be unambiguous. 15 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. After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. 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. At locations with pretimed traffic control signals or non-actuated approaches, pedestrian pushbuttons may be used to activate the accessible pedestrian signals. no pedestrian will cross the street. How much time do I need to invest? Standard: 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: Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. 05 The accessible walk indication shall have the same duration as the pedestrian walk signal except when the pedestrian signal rests in walk. Potential demand for accessible pedestrian signals; A request for accessible pedestrian signals; Traffic volumes during times when pedestrians might be present, including periods of low traffic volumes or high turn-on-red volumes; The complexity of traffic signal phasing (such as split phases, protected turn phases, leading pedestrian intervals, and exclusive pedestrian phases); and, A speech walk message for the WALKING PERSON (symbolizing WALK) indication, and. Standard: 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. 07 Audible beaconing may be provided in several ways, any of which are initiated by an extended pushbutton press. 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. 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. The animated eyes symbol shall be illuminated at the start of the walk interval and shall terminate at the end of the walk interval. 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. 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. Accessible pedestrian signals shall have both audible and vibrotactile walk indications. 14 Speech walk messages communicate to pedestrians which street has the walk interval. 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. A flashing UPRAISED HAND (symbolizing DONT WALK) signal indication means that a pedestrian shall not start to cross the roadway in the direction of the signal indication, but that any pedestrian who has already started to cross on a steady WALKING PERSON (symbolizing WALK) signal indication shall proceed to the far side of the traveled way of the street or highway, unless otherwise directed by a traffic control device to proceed only to the median of a divided highway or only to some other island or pedestrian refuge area. The information provided by an accessible pedestrian signal shall clearly indicate which pedestrian crossing is served by each device. 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. 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. 04 Countdown pedestrian signals shall consist of Portland orange numbers that are at least 6 inches in height on a black opaque background. 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. 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. Standard: 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. 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). 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 pedestrian signal head indications, the symbols should be at least 9 inches high. 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 name of the street to be crossed may also be provided in accessible format, such as Braille or raised print. 24 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.
