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. US DOT Home | FHWA Home | MUTCD Home | Operations Home | Privacy Policy, United States Department of Transportation - Federal Highway Administration. Option: The pedestrian clearance time is intended to allow pedestrians who started crossing during the walk interval to complete their crossing. 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. Guidance: 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. Speech messages might be either directly audible or transmitted, requiring a personal receiver to hear the message. 16 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: Pedestrian control signals. 01 Pedestrian signal head indications shall have the following meanings: Standard: 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. 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. The engineering study should consider the following factors: 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. 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 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. The buffer interval shall not begin later than the beginning of the red clearance interval, if used. 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. 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. They shall begin with the term "Wait," followed by intersection identification information modeled after: "Wait to cross Broadway at Grand." 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. A flashing DONT WALK pedestrian signal indicates that (1 point) the signal light will soon be yellow. Option: 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). 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. 06 Figure 4E-2 illustrates the pedestrian intervals and their possible relationships with associated vehicular signal phase intervals. 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. Pushbutton locator tones shall have a duration of 0.15 seconds or less, and shall repeat at 1-second intervals. 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. 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. 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. 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). 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. They have a pushbutton locator tone and tactile arrow, and can include audible beaconing and other special features. 23 If a leading pedestrian interval is used, consideration should be given to prohibiting turns across the crosswalk during the leading pedestrian interval. Call 905-546-4376 Email TrafficOps@hamilton.ca As part of the Accessible Ontarians with Disabilities Act (AODA), all new signalized intersections in Hamilton will be outfitted with Accessible Pedestrian Pushbuttons (APS). Other locations where a study indicates audible beaconing would be beneficial. The walk indication is displayed in white, and the don't walk indication is displayed in Portland orange. WebFlashing Don't Walk or Flashing Raised Hand. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. 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: Tactile maps of crosswalks may also be provided. These provisions also position pushbutton poles in optimal locations for installation of accessible pedestrian signals (see Sections 4E.09 through 4E.13). WebThe pedestrian clearance interval consists of a flashing "Don't Walk" signal. Support: 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. 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 audible walk indication shall be audible from the beginning of the associated 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. Unobstructed and adjacent to a level all-weather surface to provide access from a wheelchair; Where there is an all-weather surface, a wheelchair accessible route from the pushbutton to the ramp; Between the edge of the crosswalk line (extended) farthest from the center of the intersection and the side of a curb ramp (if present), but not greater than 5 feet from said crosswalk line; Between 1.5 and 6 feet from the edge of the curb, shoulder, or pavement; With the face of the pushbutton parallel to the crosswalk to be used; and. 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. Support: Guidance: The displayed period of each flash shall be a minimum of 1/2 and a maximum of 2/3 of the total flash cycle. 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. 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. 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 you have already started to cross, finish crossing the 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. 07 Section 4E.11 contains additional provisions regarding the volume and sound level of pushbutton locator tones. 14 The use of additional pedestrian detectors on islands or medians where a pedestrian might become stranded should be considered. Standard: Support: Standard: 04 The UPRAISED HAND (symbolizing DONT WALK) signal indication shall be Portland orange, conforming to the publication entitled "Pedestrian Traffic Control Signal Indications" (see Section 1A.11), with all except the symbol obscured by an opaque material. Any additional time that is required to satisfy the conditions of this paragraph should be added to the walk interval. Guidance: 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. 05 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. 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. The accessible walk indication shall have the same duration as the pedestrian walk signal except when the pedestrian signal rests in walk. 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. After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. How much time do I need to invest? A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not be used. 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. 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. 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. Accessible pedestrian signals and detectors provide information in non-visual formats (such as audible tones, speech messages, and/or vibrating surfaces). If an exclusive signal phase is provided or made available for pedestrian movements in one or more directions, with all conflicting vehicular movements being stopped; At an established school crossing at any signalized location; or. 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. 03 Pedestrian signal heads may be used under other conditions based on engineering judgment. 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). Countdown pedestrian signals shall consist of Portland orange numbers that are at least 6 inches in height on a black opaque background. Support: 07 Audible beaconing may be provided in several ways, any of which are initiated by an extended pushbutton press. Standard: 10 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. Option: Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. 09 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. 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. 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. PEDESTRIANSIGNALS 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. If a leading pedestrian interval is used, consideration should be given to prohibiting turns across the crosswalk during the leading pedestrian interval. 16 If used, a pilot light or other means of indication installed with a pedestrian pushbutton shall not be illuminated until actuation. Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. At locations with pretimed traffic control signals or non-actuated approaches, pedestrian pushbuttons may be used to activate the accessible pedestrian signals. 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. Accessible pedestrian signals shall have an audible walk indication during the walk interval only. 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) Accessible pedestrian signals that are located as close as possible to pedestrians waiting to cross the street provide the clearest and least ambiguous indication of which pedestrian crossing is served by a device. Technology that provides different sounds for each non-concurrent signal phase has frequently been found to provide ambiguous information. 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. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not be used. A red flashing DONT WALK or flashing UPRAISED HAND means that no pedestrian should enter the roadway at this time. 02 Pushbuttons for accessible pedestrian signals should be located in accordance with the provisions of Section 4E.08 and should be located as close as possible to the crosswalk line furthest from the center of the intersection and as close as possible to the curb ramp. If a leading pedestrian interval is used, the use of accessible pedestrian signals (see. Guidance: Countdown displays shall not be used during the walk interval or during the red clearance interval of a concurrent vehicular phase. Guidance: The light source of a flashing UPRAISED HAND (symbolizing DONT WALK) signal indication shall be flashed continuously at a rate of not less than 50 or more than 60 times per minute. 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. 12 If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. 06 When used, accessible pedestrian signals shall be used in combination with pedestrian signal timing. The information provided by an accessible pedestrian signal shall clearly indicate which pedestrian crossing is served by each device. 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.
