Current through Register Vol. 28, No. 5, November 1, 2024
Section 3B.18 - Crosswalk MarkingsSupport:
01 Crosswalk markings provide guidance for pedestrians who are crossing roadways by defining and delineating paths on approaches to and within signalized intersections, and on approaches to other intersections where traffic stops.02 In conjunction with signs and other measures, crosswalk markings help to alert road users of a designated pedestrian crossing point across roadways at locations that are not controlled by traffic control signals or STOP or YIELD signs.03 At non-intersection locations, crosswalk markings legally establish the crosswalk. Standard:
04 When crosswalk lines are used, they shall consist of solid white lines that mark the crosswalk. They shall not be less than 6 inches or greater than 24 inches in width. Guidance:
05 (DE Revision) If 12-inch wide transverse lines are used to mark a temporary crosswalk or patterned pavement crosswalk or along non-state maintained roadways, the crosswalk width should be measured between the two lines (see Figure 3B-19).05A (DE Revision) Crosswalk markings on roadways with a posted speed limit (or 85th-percentile speed) of 40 mph or greater and at locations with high pedestrian activity should be 10 feet wide. Crosswalk markings on other roadways should be 6 feet wide.05B (DE Revision) Crosswalk markings on all approaches to an intersection with one or more roadways with a posted speed limit (or 85th-percentile speed) of 40 mph or greater or with high pedestrian activity should be 10 feet wide.06 Crosswalk lines, if used on both sides of the crosswalk, should extend across the full width of pavement or to the edge of the intersecting crosswalk to discourage diagonal walking between crosswalks (see Figure 3B-19).07 At locations controlled by traffic control signals or on approaches controlled by STOP or YIELD signs, crosswalk lines should be installed where engineering judgment indicates they are needed to direct pedestrians to the proper crossing path(s).08 Crosswalk lines should not be used indiscriminately. An engineering study should be performed before a marked crosswalk is installed at a location away from a traffic control signal or an approach controlled by a STOP or YIELD sign. The engineering study should consider the number of lanes, the presence of a median, the distance from adjacent signalized intersections, the pedestrian volumes and delays, the average daily traffic (ADT), the posted or statutory speed limit or 85th-percentile speed, the geometry of the location, the possible consolidation of multiple crossing points, the availability of street lighting, and other appropriate factors.09 New marked crosswalks alone, without other measures designed to reduce traffic speeds, shorten crossing distances, enhance driver awareness of the crossing, and/or provide active warning of pedestrian presence, should not be installed across uncontrolled roadways where the speed limit exceeds 40 mph and either: A. The roadway has four or more lanes of travel without a raised median or pedestrian refuge island and an ADT of 12,000 vehicles per day or greater; orB. The roadway has four or more lanes of travel with a raised median or pedestrian refuge island and an ADT of 15,000 vehicles per day or greater. Support:
10 Chapter 4F contains information on Pedestrian Hybrid Beacons. Section 4L.03 contains information regarding Warning Beacons to provide active warning of a pedestrian's presence. Section 4N.02 contains information regarding In-Roadway Warning Lights at crosswalks. Chapter 7D contains information regarding school crossing supervision. Guidance:
11 Because non-intersection pedestrian crossings are generally unexpected by the road user, warning signs (see Section 2C.50) should be installed for all marked crosswalks at non-intersection locations and adequate visibility should be provided by parking prohibitions. Support:
12 Section 3B.16 contains information regarding placement of stop line markings near crosswalk markings. Option:
13 (DE Revision) Paragraph deleted.14 (DE Revision) Paragraph deleted. Standard:
15 (DE Revision) If crosswalk markings along state-maintained roadways are used for permanent applications other than with patterned pavement or other aesthetic treatments, they shall consist of 24-inch wide solid white longitudinal lines separated by gaps of 24 inches (see Figure 3B-19). Guidance:
15A (DE Revision) The design and placement of the lines and gaps should avoid the wheel paths if possible.15B (DE Revision) When patterned pavement or other aesthetic treatments are used to depict crosswalks, 12-inch wide transverse solid white lines should be used to define the crosswalk. Option:
15C (DE Revision) Twelve-inch solid white transverse crosswalk markings may be used for temporary crosswalk installations (see Chapter 6F for additional guidance).16 When an exclusive pedestrian phase that permits diagonal crossing of an intersection is provided at a traffic control signal, a marking as shown in Figure 3B-20 may be used for the crosswalk. Guidance:
16A (DE Revision) Crosswalk markings accommodating diagonal pedestrian crossings are discouraged and should not be used along state-maintained roadways unless approved by DelDOT Traffic.17 Crosswalk markings should be located so that the curb ramps are within the extension of the crosswalk markings. Support:
18 Detectable warning surfaces mark boundaries between pedestrian and vehicular ways where there is no raised curb. Detectable warning surfaces are required by 49 CFR, Part 37 and by the Americans with Disabilities Act (ADA) where curb ramps are constructed at the junction of sidewalks and the roadway, for marked and unmarked crosswalks. Detectable warning surfaces contrast visually with adjacent walking surfaces, either light-on-dark, or dark-on-light. The "Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities (ADAAG)" (see Section 1A.11) contains specifications for design and placement of detectable warning surfaces.2 Del.
