Retroreflective or internally illuminated raised pavement markers, or non-retroreflective raised pavement markers supplemented by retroreflective or internally illuminated markers, may be substituted for markings of other types. 18 Detectable warning surfaces mark boundaries between pedestrian and vehicular ways where there is no raised curb. endstream endobj 60 0 obj <> endobj 61 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/Type/Page>> endobj 62 0 obj <>stream Guidance: First Name. A channelizing line shall be a wide or double solid white line. The longitudinal spacing of the chevrons or diagonal lines should be determined by engineering judgment considering factors such as speeds and desired visual impacts. A normal line may be used to extend a wide line through an intersection. Guidance: Improvements on Interstate 55 include pavement resurfacing and patching, shoulder maintenance and culvert repairs. Standard: 29 Wide solid lane line markings may be used for greater emphasis. Support: Additional parking space markings for the purpose of designating spaces for use only by persons with disabilities are discussed in, Word, symbol, and arrow markings on the pavement are used for the purpose of guiding, warning, or regulating traffic. 03 On two-way, two- or three-lane roadways where center line markings are installed, no-passing zones shall be established at vertical and horizontal curves and other locations where an engineering study indicates that passing must be prohibited because of inadequate sight distances or other special conditions. The lane drop marking should begin no closer to the intersection than the most upstream regulatory or warning sign associated with the lane drop. Curb markings without word markings or signs may be used to convey a general prohibition by statute of parking within a specified distance of a stop sign, YIELD sign, driveway, fire hydrant, or crosswalk. 18 Section 8B.28 contains information regarding the use of stop lines and yield lines at grade crossings. Option: 11 The value of N cited in Sections 3B.12 through 3B.14 for the spacing of raised pavement markers shall equal the length of one line segment plus one gap of the broken lines used on the highway. 17 The dotted white lane lines that are used for lane drop markings and that are used as a lane line separating through lanes from auxiliary lanes should consist of line segments that are 3 feet in length separated by 9-foot gaps. 02 See Chapter 3E for additional information on approach markings for toll plaza islands. Among the word, symbol, and arrow markings that may be used are the following: Standard: IDOT policy provides the direction necessary to provide a safe work zone while maintaining mobility. If used, speed reduction markings should supplement the appropriate warning signs and other traffic control devices and should not substitute for these devices. Option: Center line markings should also be placed on other traveled ways where an engineering study indicates such a need. Option: Edge line markings shall be placed on paved streets or highways with the following characteristics: Edge line markings should be placed on paved streets or highways with the following characteristics: Edge line markings should not be placed where an engineering study or engineering judgment indicates that providing them is likely to decrease safety. Section 11-307 of the "Uniform Vehicle Code (UVC)" contains further information regarding required road user behavior in no-passing zones. Guidance: 01 If speed hump markings are used, they shall be a series of white markings placed on a speed hump to identify its location. 10 Except for the SCHOOL word marking (see Section 7C.03), pavement word, symbol, and arrow markings should be no more than one lane in width. 01 No-passing zones shall be marked by either the one direction no-passing zone pavement markings or the two-direction no-passing zone pavement markings described in Section 3B.01 and shown in Figures 3B-1 and 3B-3. Support: The bidirectional marker is capable of displaying the applicable color for each direction of travel. At least one raised marker every N shall be retroreflective or internally illuminated. 23 Where opposing offset channelized left-turn lanes exist, lane-use arrow markings should be placed near the downstream terminus of the offset left-turn lanes to reduce wrong-way movements (see Figure 2B-17). Guidance: 07 Where curbs are marked for delineation or visibility purposes, the colors shall comply with the general principles of markings (see Section 3A.05). Option: The chevrons and diagonal lines used for crosshatch markings should be at least 12 inches wide for roadways having a posted or statutory speed limit of 45 mph or greater, and at least 8 inches wide for roadways having posted or statutory speed limit of less than 45 mph. 09 The individual triangles comprising the yield line should have a base of 12 to 24 inches wide and a height equal to 1.5 times the base. In such applications, markers may be positioned in line with or immediately adjacent to a single line marking, or positioned between the two lines of a double center line or double lane line marking. Anyone, 5 years of age and older, is eligible to receive the COVID-19 vaccine. In advance of the point of divergence, a wide solid white line or normal solid double white line shall be extended in place of the broken lane line for a distance equal to the length of the diverging lines (see Drawing C of, If traffic can pass either to the right or left of the obstruction, additional white chevron crosshatch markings (see.

A pavement structure consisting of HMA surface course overlaying a Portland Cement Concrete (PCC) or Roller Compacted Concrete (RCC) slab of relatively high bending resistance which serves as the principle load-distributing component. Guidance: Standard: 04 White two-way left-turn lane-use arrows (see Figure 3B-7), should be used in conjunction with the longitudinal two-way left-turn markings at the locations described in Section 3B.20. When supplementing line extensions through freeway interchanges, a spacing of no greater than N should be used. 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. Word, symbol, and arrow markings shall be white, except as otherwise provided in this Section. These pavement markings can be helpful to road users in some locations by supplementing signs and providing additional emphasis for important regulatory, warning, or guidance messages, because the markings do not require diversion of the road user's attention from the roadway surface. . Examples of standard word and arrow pavement markings are shown in Figures 3B-23 and 3B-24. DOCX Preformed Plastic Pavement Marking Type D - Inlaid %PDF-1.6 % webapps1.dot.illinois.gov An arrow at the downstream end of a turn lane can help to prevent wrong way movements. PAVEMENT MARKING TAPE, TYPE IV 8" Base items 78000100 . 13 If yield (stop) lines are used at a crosswalk that crosses an uncontrolled multi-lane approach, Yield Here To (Stop Here For) Pedestrians (R1-5 series) signs (see Section 2B.11) shall be used. Standard: 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 Figures 3B-17 and 3B-19). The following are manuals, guides and forms provided to comply with construction projects for IDOT and local entities. 03 At non-intersection locations, crosswalk markings legally establish the crosswalk. 05 If transverse lines are used to mark a crosswalk, the gap between the lines should not be less than 6 feet.

The number of different word and symbol markings used should be minimized to provide effective guidance and avoid misunderstanding. Standard: Pavement Marking Standards Click on the individual link below to download the file. Support: 07 Where the distance between successive no-passing zones is less than 400 feet, no-passing markings should connect the zones. Center line markings should also be placed on all rural arterials and collectors that have a traveled way of 18 feet or more in width and an ADT of 3,000 vehicles per day or greater. Guidance: Transverse markings, which include shoulder markings, word and symbol markings, arrows, stop lines, yield lines, crosswalk lines, speed measurement markings, speed reduction markings, speed hump markings, parking space markings, and others, shall be white unless otherwise provided in this Manual. 16 A yield-ahead triangle symbol (see Figure 3B-26) or YIELD AHEAD word pavement marking may be used on approaches to intersections where the approaching traffic will encounter a YIELD sign at the intersection. At non-intersection locations, crosswalk markings legally establish the crosswalk. 11 Engineering judgment should be used in determining whether to place center line markings on traveled ways that are less than 16 feet wide because of the potential for traffic encroaching on the pavement edges, traffic being affected by parked vehicles, and traffic encroaching into the opposing traffic lane. 14 Except at the ends of aisles in parking lots, the word STOP shall not be used on the pavement unless accompanied by a stop line (see Section 3B.16) and STOP sign (see Section 2B.05). Article 8.3.1 Revised the Application section. Since yellow and white curb markings are frequently used for curb delineation and visibility, it is advisable to establish parking regulations through the installation of standard signs (see, Where curbs are marked for delineation or visibility purposes, the colors shall comply with the general principles of markings (see. 13 Yellow diagonal crosshatch markings (see Section 3B.24) may be placed in the flush median area between the two sets of no-passing zone markings as shown in Figure 3B-5. Guidance: 08 Where center line markings are used, no-passing zone markings shall be used on approaches to grade crossings in compliance with Section 8B.27. Center line pavement markings, when used, shall be the pavement markings used to delineate the separation of traffic lanes that have opposite directions of travel on a roadway and shall be yellow. 12 If yield or stop lines are used at a crosswalk that crosses an uncontrolled multi-lane approach, the yield lines or stop lines should be placed 20 to 50 feet in advance of the nearest crosswalk line, and parking should be prohibited in the area between the yield or stop line and the crosswalk (see Figure 3B-17). 24 An arrow at the downstream end of a turn lane can help to prevent wrong way movements.
