Option: Guidance: 09 The number of different word and symbol markings used should be minimized to provide effective guidance and avoid misunderstanding. Channelizing lines may be used to form channelizing islands where traffic traveling in the same direction is permitted on both sides of the island. 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.

Option: Raised pavement markers also may be used to supplement other markings such as channelizing islands, gore areas, approaches to obstructions, or wrong-way arrows. If used, the pattern of the raised pavement markers should simulate the pattern of the markings for which they substitute. 09 If traffic can pass either to the right or left of the obstruction, the markings shall consist of two channelizing lines diverging from the lane line, one to each side of the obstruction. 03 Retroreflective or internally illuminated raised pavement markers may be used in the roadway immediately adjacent to curbed approach ends of raised medians and curbs of islands, or on top of such curbs (see Section 3B.23). These markings shall be placed with the broken line toward the two-way left-turn lane and the solid line toward the adjacent traffic lane as shown in, White two-way left-turn lane-use arrows (see, Signs should be used in conjunction with the two-way left turn markings (see, If a continuous flush median island formed by pavement markings separating travel in opposite directions is used, two sets of solid double yellow lines shall be used to form the island as shown in. Yield lines shall not be used at locations where drivers are required to stop in compliance with a STOP (R1-1) sign, a Stop Here For Pedestrians (R1-5b or R1-5c) sign, a traffic control signal, or some other traffic control device. Ask a Question for Contract 238-46582. Can IDOT provide any cores that were previously taken for the existing conditions on I-55. Symbol messages are preferable to word messages. If authorized by law, Do Not Block Intersection markings with appropriate signs may also be used at other locations. Option: 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. %%EOF Lane line markings should also be used at congested locations where the roadway will accommodate more traffic lanes with lane line markings than without the markings. 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. DOCX Temporary Pavement Marking 03 If advance speed hump markings are used, they shall be a series of eight white 12-inch transverse lines that become longer and are spaced closer together as the vehicle approaches the speed hump or other deflection.

It is recommended that a designer retrieves the most current version of any detail before beginning the "Pavement Marking Plan" design process. 26 Where through lanes approaching an intersection become mandatory turn lanes, ONLY word markings (see Figure 3B-23) should be used in addition to the required lane-use arrow markings and signs (see Sections 2B.19 and 2B.20). SEARCH THE DOT WEBSITE SEARCH OUR A-Z INDEX Lane line markings should be used on all roadways that are intended to operate with two or more adjacent traffic lanes in the same direction of travel, except as otherwise required for reversible lanes. Other markings in the median island area shall also be yellow, except crosswalk markings which shall be white (see Section 3B.18). If you are unable to open these files, please navigate to the troubleshooting webpage for assistance. Sections 11-301(c) and 11-311(c) of the "Uniform Vehicle Code (UVC)" contain information regarding left turns across center line no-passing zone markings and paved medians, respectively. 25 Where through lanes approaching an intersection become mandatory turn lanes, lane-use arrow markings (see Figure 3B-24) shall be used and shall be accompanied by standard signs. Raised pavement markers should not substitute for right-hand edge line markings unless an engineering study or engineering judgment indicates the benefits of enhanced delineation of a curve or other location would outweigh possible impacts on bicycles using the shoulder, and the spacing of raised pavement markers on the right-hand edge line is close enough to avoid misinterpretation as a broken line during wet night conditions. 02 The side of a raised pavement marker that is visible to traffic proceeding in the wrong direction may be red (see Section 3A.05). Dotted edge line extensions may be placed through intersections or major driveways. 01 Do Not Block Intersection markings may be used to mark the edges of an intersection area that is in close proximity to a signalized intersection, railroad crossing, or other nearby traffic control that might cause vehicles to stop within the intersection and impede other traffic entering the intersection. endstream endobj 78 0 obj <> endobj 79 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 0/Type/Page>> endobj 80 0 obj <>stream The diagonal markings shall be white when used on right-hand shoulders. The following manuals, guides, specifications, and forms are provided to help you do business with IDOT. 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. Work zone safety is of the utmost importance. 12 Retroreflective or internally illuminated raised pavement markers of the appropriate color may be placed on the pavement in front of the curb and/or on the top of curbed as of raised medians and curbs of islands, as a supplement to or substitute for retroreflective curb markings used for delineation. 06 Stop lines shall consist of solid white lines extending across approach lanes to indicate the point at which the stop is intended or required to be made. Standard: Standard: 10 Center line markings should be placed on paved urban arterials and collectors that have a traveled way of 20 feet or more in width and an ADT of 4,000 vehicles per day or greater. Standard: Yield lines may be used to indicate the point behind which vehicles are required to yield in compliance with a YIELD (R1-2) sign or a Yield Here To Pedestrians (R1-5 or R1-5a) sign. Directional configurations also should be used to avoid confusion resulting from visibility of markers that do not apply to the road user. 02 Except as provided in Paragraph 3, where pavement markings are used, lane-reduction transition markings shall be used to guide traffic through transition areas where the number of through lanes is reduced, as shown in Figure 3B-14. Pavement Marking Standards Click on the individual link below to download the file. Guidance: Standard: 03 If used, speed reduction markings shall be a series of white transverse lines on both sides of the lane that are perpendicular to the center line, edge line, or lane line. The color of raised pavement markers under both daylight and nighttime conditions shall conform to the color of the marking for which they serve as a positioning guide, or for which they supplement or substitute. 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. 36 Where crossroad channelization or ramp geometrics do not make wrong-way movements difficult, the appropriate lane-use arrow should be placed in each lane of an exit ramp near the crossroad terminal where it will be clearly visible to a potential wrong-way road user (see Figure 2B-18). THE SOLID YELLOW PAVEMENT MARKINGS 2 SHOULD GENERALLY START OR END NEAR THE RADIUS POINT OF EACH STREET RETURN EXCEPT WHERE ONE OR BOTH ENDS WOULD INCLUDE STOP BARS. 06 Word and symbol markings should not exceed three lines of information. THE SKIP-DASH PAVEMENT MARKINGS 1 OR 7 SHOULD BE CENTERED BETWEEN BOTH ENDS OF EACH CITY BLOCK AND SHALL BE PLACED SO THEY LINE UP ACROSS FROM EACH OTHER. Except for dotted edge line extensions (see. The UVC can be obtained from the National Committee on Uniform Traffic Laws and Ordinances at the address shown on Page i. Option: webapps1.dot.illinois.gov 33 The ONLY word marking shall not be used in a lane that is shared by more than one movement. 19 Section 3B.09 contains information about the lane line markings that are to be used for transition areas where the number of through lanes is reduced. Section 3B.16 contains information regarding placement of stop line markings near crosswalk markings. 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. Center line markings should also be placed on other traveled ways where an engineering study indicates such a need. 07 When substituting for wide lines, raised pavement markers may be placed laterally adjacent to each other to simulate the width of the line. See, Pavement markings shall be used to guide traffic away from fixed obstructions within a paved roadway. The applicable Standards are referenced on the cover sheet of the plans. 09 In addition to pavement markings, no-passing zone signs (see Sections 2B.28, 2B.29, and 2C.45) may be used to emphasize the existence and extent of a no-passing zone. Lane-reduction transition markings are not used for lane drops. Standard: 10 If traffic can pass either to the right or left of the obstruction, additional white chevron crosshatch markings (see Section 3B.24) may be placed in the flush median area between the channelizing lines as shown in Drawing C of Figure 3B-15. This special provision was developed by the Bureau of Materials and Physical Research and the Bureau of Operations to create a statewide specification for a temporary pavement marking tape with improved retroreflectivity during wet conditions. 01 Lane-reduction transition markings are used where the number of through lanes is reduced because of narrowing of the roadway or because of a section of on-street parking in what would otherwise be a through lane. Support: Stop lines may be used to indicate the point behind which vehicles are required to stop in compliance with a STOP (R1-1) sign, a Stop Here For Pedestrians (R1-5b or R1-5c) sign, or some other traffic control device that requires vehicles to stop, except YIELD signs that are not associated with passive grade crossings. A single-direction lane-use arrow shall not be used in a lane bordered on both sides by yellow two-way left-turn lane longitudinal markings. 16 Lane drop markings used in advance of lane drops at intersections should begin a distance in advance of the intersection that is determined by engineering judgment as suitable to enable drivers who do not desire to make the mandatory turn to move out of the lane being dropped prior to reaching the queue of vehicles that are waiting to make the turn. Solid lines shall not be used to extend edge lines into or through intersections or major driveways. Option: Option: On approaches to intersections, a solid white lane line marking should be used to separate a through lane from an added mandatory turn lane. 03 Other pavement markings in the channelizing island area shall be white. 08 For exit ramps with a parallel deceleration lane, a normal width dotted white line extension may be installed in the taper area upstream from the full-width deceleration lane as shown in Drawings A and C of Figure 3B-8. Discontinuation of the Use of Fog Seals 01 A channelizing line shall be a wide or double solid white line. The diagonal markings shall be yellow when used on the left-hand shoulders of the roadways of divided highways and on the left-hand shoulders of one-way streets or ramps. The passing sight distance on a vertical curve is the distance at which an object 3.5 feet above the pavement surface can be seen from a point 3.5 feet above the pavement (see Figure 3B-4). This website utilizes varied software, media tools, files and applications to present or make available varied information. When diagonal or longitudinal lines are used to mark a crosswalk, the transverse crosswalk lines may be omitted. The UVC can be obtained from the National Committee on Uniform Traffic Laws and Ordinances at the address shown on Page i. 9. 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.
