Current through Register Vol. 28, No. 5, November 1, 2024
Section 4E.08 - Pedestrian DetectorsOption:
01 Pedestrian detectors may be pushbuttons or passive detection devices. Support:
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. 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.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. These provisions also position pushbutton poles in optimal locations for installation of accessible pedestrian signals (see Sections 4E.09 through 4E.13). Information regarding reach ranges can be found in the "Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities (ADAAG)" (see Section 1A.11). Guidance:
04 (DE Revision) If pedestrian pushbuttons are used, they should be capable of easy activation and conveniently located near each end of the crosswalks. Except as provided in Paragraphs 5 and 6, pedestrian pushbuttons should be located to meet all of the following criteria (see Figure 4E-3):A. Unobstructed and adjacent to a level all-weather surface to provide access from a wheelchair;B. Where there is an all-weather surface, a wheelchair accessible route from the pushbutton to the ramp;C. 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;D. Between 1.5 and 10 feet from the edge of the curb, shoulder, or pavement;E. With the face of the pushbutton parallel to the crosswalk to be used; andF. At a mounting height of approximately 3.5 feet, but no more than 4 feet, above the sidewalk.G. Within 10 inches of the 50:1 landing area; andH. With an extended 50:1 landing area measuring a minimum of 18 inches behind the centerline of the face of the pushbutton.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.06 (DE Revision) Paragraph deleted.06A (DE Revision) In locations where there is an increased likelihood of the pedestrian pushbutton pole being struck, the pole should be placed as far as possible from the edge of traveled way, but not farther than 10 feet from the edge of curb, shoulder, or pavement.07 Except as provided in Paragraph 8, where two pedestrian pushbuttons are provided on the same corner of a signalized location, the pushbuttons should be separated by a distance of at least 10 feet.

Option:
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. Support:
10 Signs (see Section 2B.52) shall be mounted adjacent to or integral with pedestrian pushbuttons, explaining their purpose and use. Option:
11 At certain locations, a supplemental sign in a more visible location may be used to call attention to the pedestrian pushbutton. Standard:
12 The positioning of pedestrian pushbuttons and the legends on the pedestrian pushbutton signs shall clearly indicate which crosswalk signal is actuated by each pedestrian pushbutton. Option:
12A (DE Revision) At intersections on state-maintained roads where pedestrian pushbuttons are co-mounted on poles, physical arrows on the pushbuttons may be used instead of arrows on pedestrian pushbutton signs to indicate which crosswalk is actuated by each pedestrian pushbutton. Standard:
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. Guidance:
14 The use of additional pedestrian detectors on islands or medians where a pedestrian might become stranded should be considered.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. Standard:
16 If used, a pilot light or other means of indication installed with a pedestrian pushbutton shall not be illuminated until actuation. Once it is actuated, the pilot light shall remain illuminated until the pedestrian's green or WALKING PERSON (symbolizing WALK) signal indication is displayed.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." Option:
18 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. Standard:
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.2 Del. Admin. Code § 4E.08
