Support: On new construction, where no posted or statutory speed limit has been established, the design speed may be used in the transition taper length formula. 03 Do Not Block Intersection markings shall be accompanied by one or more Do Not Block Intersection (DRIVEWAY) (CROSSING) (R10-7) signs (see Section 2B.53), one or more Do Not Stop On Tracks (R8-8) signs (see Section 8B.09), or one or more similar signs. Permanent Intersection Tape - Intended for crosswalks, gore lines, and symbols at intersections where markings are subjected to high shear from turning traffic. 07 When substituting for wide lines, raised pavement markers may be placed laterally adjacent to each other to simulate the width of the line.

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. 03 Where highway design or reduced visibility conditions make it desirable to provide control or to guide vehicles through an intersection or interchange, such as at offset, skewed, complex, or multi-legged intersections, on curved roadways, where multiple turn lanes are used, or where offset left turn lanes might cause driver confusion, dotted line extension markings consisting of 2-foot line segments and 2- to 6-foot gaps should be used to extend longitudinal line markings through an intersection or interchange area. Reference Material - Illinois Tollway These certificates must be submitted along with the contractor's original BC 57 Affidavit of Availability. 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. Guidance: 5 0 obj <> endobj 19 0 obj <>stream If you are interested in becoming or working with an approved lab that performs material testing on behalf of IDOT please choose from the following: Cement, Concrete, Soils. 10 The spacing of raised pavement markers used to supplement or substitute for other types of longitudinal markings should correspond with the pattern of broken lines for which the markers supplement or substitute. This 2022 report provides technical guidance on methods for maintaining pavement marking retroreflectivity in accordance with the MUTCD. First Name. 01 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. hb``b`` Where greater restriction is required, solid lane lines or channelizing lines should be extended into or continued through intersections or major driveways. If markings are used for a speed hump that does not also function as a crosswalk or speed table, the markings shall comply with Option A, B, or C shown in, Advance pavement wording such as BUMP or HUMP (see, 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. Option: Standard: THERMOPLASTIC PAVEMENT MARKING - LETTERS AND SYMBOLS Base items 78000400 FOOT THERMOPLASTIC PAVEMENT MARKING - LINE 6" . Edge line markings may be excluded, based on engineering judgment, for reasons such as if the traveled way edges are delineated by curbs, parking, or other markings. <]/Prev 655708>> Chapter 3B - MUTCD 2009 Edition - FHWA - Transportation 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 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). Standard: 01 If speed hump markings are used, they shall be a series of white markings placed on a speed hump to identify its location. 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. For additional emphasis, retroreflective raised pavement markers may be spaced closer than described in, Figures 9-20 through 9-22 in the "Traffic Control Devices Handbook" (see. 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. Except for acceleration lanes, where a lane-reduction transition occurs on a roadway with a speed limit of less than 45 mph, the lane-reduction arrow markings shown in Drawing f in Figure 3B-24 should be used if determined to be appropriate based on engineering judgment. Also revised sign illust r ation s P-IT14A, P-IT17A, and P-IT17B to 14 Days. 0000409605 00000 n Speed reduction markings should not be greater than 12 inches in width, and should not extend more than 18 inches into the lane. Standard: 23 In the case of a lane drop at an exit ramp or intersection, such a solid white line may replace a portion, but not all of the length of the wide dotted white lane line. If a bicycle lane is marked on the outside portion of the traveled way, the edge line that would mark the outside edge of the bicycle lane may be omitted. Support: "/L@ND% - webapps1.dot.illinois.gov Figure 3B-7 Example of Two-Way Left-Turn Lane Marking Applications. 03 At non-intersection locations, crosswalk markings legally establish the crosswalk. The diagonal markings shall be white when used on right-hand shoulders. Standard: 08 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. Guidance: On three-lane roadways where the direction of travel in the center lane transitions from one direction to the other, a no-passing buffer zone shall be provided in the center lane as shown in. Speed measurement markings, if used, shall be white, and shall not be greater than 24 inches in width. 01 Word, symbol, and arrow markings on the pavement are used for the purpose of guiding, warning, or regulating traffic. Following a major snowstorm in The UVC can be obtained from the National Committee on Uniform Traffic Laws and Ordinances at the address shown on Page i. 22 Where lane changes might cause conflicts, a wide or normal solid white lane line may extend upstream from an intersection. 10 White chevron crosshatch markings (see Section 3B.24) may be placed in the neutral area of exit ramp and entrance ramp gores for special emphasis as shown in Figures 3B-8 and 3B-10 and Drawing A of Figure 3B-9. Support: LCDOT Heading - Contract Specifications Shell. The design of the lines and gaps should avoid the wheel paths if possible, and the gap between the lines should not exceed 2.5 times the width of the diagonal or longitudinal lines.
