An alert tone can be particularly useful if the walk tone is not easily audible in some traffic conditions. 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. Support: 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. 09 The volume of audible walk indications and pushbutton locator tones (see Section 4E.12) should be set to be a maximum of 5 dBA louder than ambient sound, except when audible beaconing is provided in response to an extended pushbutton press. 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. Standard: 04 Countdown pedestrian signals shall consist of Portland orange numbers that are at least 6 inches in height on a black opaque background. 14 Speech walk messages communicate to pedestrians which street has the walk interval. 07 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. 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. 01 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. 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. At signalized locations with a demonstrated need and subject to equipment capabilities, pedestrians with special needs may be provided with additional crossing time by means of an extended pushbutton press. 06 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. 10 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. 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. 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. The walk interval is intended for pedestrians to start their crossing. 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) Standard: It need not be repeated for the entire time that the walk interval is not timing. 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. 01 Accessible pedestrian signals and detectors provide information in non-visual formats (such as audible tones, speech messages, and/or vibrating surfaces). This can be done by means of a speech pushbutton information message (see. If the pedestrian signal rests in walk, the accessible walk indication should be limited to the first 7 seconds of the walk interval. 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. 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. Special signal/flashing signal Special signals or flashing signals are used in specific situations, such as school zones, construction zones, and emergency vehicle preemption. 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: The signal for pedestrians to walk is a white walking symbol. 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 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. Standard: 05 Not all crosswalks at an intersection need audible beaconing; audible beaconing can actually cause confusion if used at all crosswalks at some intersections. Option: Vibrotactile walk indications shall be provided by a tactile arrow on the pushbutton (see. 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). 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. 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. 07 Section 4E.11 contains additional provisions regarding the volume and sound level of pushbutton locator tones. WebPedestrian-control signal indications. At a mounting height of approximately 3.5 feet, but no more than 4 feet, above the sidewalk. Accessible pedestrian signals shall have both audible and vibrotactile walk indications. 05 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. 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. 20 If a leading pedestrian interval is used, the use of accessible pedestrian signals (see Sections 4E.09 through 4E.13) should be considered. Support: 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. If pedestrian signal heads are mounted on the same support as vehicular signal heads, there shall be a physical separation between them. WebA sign is normally mounted above the pedestrian detector explaining its purpose, and the position of the push button will tell which crosswalk signal is activated by which push-button. ", Option: 01 Pedestrian signal heads provide special types of traffic signal indications exclusively intended for controlling pedestrian traffic. (b) A flashing DON'T WALK or WAIT or approved Upraised Hand symbol with a countdown signal indicating the time remaining for a pedestrian to cross the roadway means a pedestrian facing the signal may start to cross the roadway in the direction of the signal but must complete the crossing prior to the display of the steady 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. 03 Vibrotactile walk indications shall be provided by a tactile arrow on the pushbutton (see Section 4E.12) that vibrates during the walk interval. If thesignal showssteady DONTWALK, it isnot safe to be in the crosswalk. Except as provided in. 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). 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. Tactile maps of crosswalks may also be provided. Standard Highway Signs and Markings (SHSM) BookDesign Details, Interpretations Standard: 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. Audible beaconing is not appropriate at locations with channelized turns or split phasing, because of the possibility of confusion. 09 Figure 4E-4 shows typical pedestrian pushbutton locations for a variety of situations. When used, accessible pedestrian signals shall be used in combination with pedestrian signal timing. 02 Engineering judgment should determine the need for separate pedestrian signal heads (see Section 4D.03) and accessible pedestrian signals (see Section 4E.09). 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. 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). 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. 03 Pedestrian signal heads may be used under other conditions based on engineering judgment. 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. Guidance: ", 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.". 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. The displayed period of each flash shall be a minimum of 1/2 and a maximum of 2/3 of the total flash cycle. An accessible pedestrian pushbutton shall incorporate a locator tone. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed. 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. Therefore, it is desirable to give users of accessible pedestrian signals the name of the street controlled by the pushbutton. Guidance: Guidance: 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. These provisions also position pushbutton poles in optimal locations for installation of accessible pedestrian signals (see Sections 4E.09 through 4E.13). 02 If pedestrian signal heads are mounted on the same support as vehicular signal heads, there shall be a physical separation between them. Audible tone walk indications shall repeat at eight to ten ticks per second. This indicates that no action is required from motorists, as no pedestrians have activated the crosswalk. 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. Option: If a pilot light is used at an accessible pedestrian signal location (see. Guidance: 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. 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. How much time do I need to invest? 04 Pushbutton locator tones shall have a duration of 0.15 seconds or less, and shall repeat at 1-second intervals. 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. 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. Pedestrian signal heads provide special types of traffic signal indications exclusively intended for controlling pedestrian traffic. 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. 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. 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. Standard: 10 Accessible pedestrian signals are typically integrated into the pedestrian detector (pushbutton), so the audible tones and/or messages come from the pushbutton housing. Support: 07 Audible beaconing may be provided in several ways, any of which are initiated by an extended pushbutton press. The accessible walk indication shall have the same duration as the pedestrian walk signal except when the pedestrian signal rests in walk. Support: A pedestrian 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. Option: Support: 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). Guidance: Accessible pedestrian signal detectors may be pushbuttons or passive detection devices. If a traffic control signal is justified by an engineering study and meets either Warrant 4, Pedestrian Volume or Warrant 5, School Crossing (see. 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 WebPedestrian signals are special types of traffic-signal indications installed for the exclusive purpose of controlling pedestrian traffic. 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. 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. Additionally, orientation and mobility specialists or similar staff also might be able to provide a wide range of advice. 10 Automatic volume adjustment in response to ambient traffic sound level shall be provided up to a maximum volume of 100 dBA. 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. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not be used. 04 Accessible pedestrian signals shall have an audible walk indication during the walk interval only. Option: The information provided by an accessible pedestrian signal shall clearly indicate which pedestrian crossing is served by each device. After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. Furthermore, low traffic volumes might make it difficult for pedestrians who have visual disabilities to discern signal phase changes. 11 At certain locations, a supplemental sign in a more visible location may be used to call attention to the pedestrian pushbutton. 02 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. 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 you have entered the They are frequently installed at signalized 03 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. After the countdown displays zero, the display shall remain dark until the beginning of the next countdown. Support: Standard: 12 If pedestrian volumes and characteristics do not require a 7-second walk interval, walk intervals as short as 4 seconds may be used. Any additional time that is required to satisfy the conditions of this paragraph should be added to the walk interval. 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. Guidance: Pedestrians who have not entered the road yet must push the activation button and await the next WALK signal. 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. 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. WebThe pedestrian phase consists of three intervals: walk; pedestrian clearance, commonly referred to as flashing dont walk (FDW); and solid dont walk. Figure 4E-4 Typical Pushbutton Locations (Sheet 1 of 2). 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. If information on intersection signalization or geometry is also given, it shall follow the intersection identification information. 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. Support: 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. Audible beaconing is not appropriate at locations with channelized turns or split phasing, because of the possibility of confusion. 13 An alert tone can be particularly useful if the walk tone is not easily audible in some traffic conditions. 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. Guidance: Option: Option: Support: The information provided by an accessible pedestrian signal shall clearly indicate which pedestrian crossing is served by each device. Guidance: 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. ", 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.". 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. 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. A flashing WALKING PERSON (symbolizing WALK) signal indication has no meaning and shall not Pedestrians who are currently crossing may continue across the road. PEDESTRIANSIGNALS 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). 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. 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. 05 Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. Guidance: 01 Technology that provides different sounds for each non-concurrent signal phase has frequently been found to provide ambiguous information. They have a pushbutton locator tone and tactile arrow, and can include audible beaconing and other special features. 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. you should prepare to 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. The walk interval typically Under stop-and-go operation, accessible pedestrian signals shall not be limited in operation by the time of day or day of week. 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. Standard: 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. They have a pushbutton locator tone and tactile arrow, and can include audible beaconing and other special features. At certain locations, a supplemental sign in a more visible location may be used to call attention to the pedestrian pushbutton. 08 Accessible pedestrian signal detectors may be pushbuttons or passive detection devices. 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. 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. 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. A flashing or steady orange hand symbol means pedestrians must not begin to cross. 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. According to the city's Traffic Engineering department, the cost, not including labor and engineering, is $1,230 for two buttons, enough for one crossing.These signals typically take two to three months from the time an individual makes a request to Option: Pushbutton locator tones shall be deactivated when the traffic control signal is operating in a flashing mode. Automatic volume adjustment in response to ambient traffic sound level shall be provided up to a maximum volume of 100 dBA.
