Crosswalk markings should be located so that the curb ramps are within the extension of the crosswalk markings. webapps1.dot.illinois.gov Chapter 3B - MUTCD 2009 Edition - FHWA - Transportation 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 Figure 3B-15). The use of retroreflective or internally illuminated raised pavement markers for supplementing longitudinal line markings should comply with the following: Raised pavement markers should not supplement right-hand edge lines 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 is close enough to avoid misinterpretation as a broken line during wet night conditions. 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. Standard Details | Lake County, IL Guidance: 03 On low-speed urban roadways where curbs clearly define the roadway edge in the lane-reduction transition, or where a through lane becomes a parking lane, the edge line and/or delineators shown in Figure 3B-14 may be omitted as determined by engineering judgment. Support: Lane-reduction transition markings are not used for lane drops. 13 For added visibility, the area of the crosswalk may be marked with white diagonal lines at a 45-degree angle to the line of the crosswalk or with white longitudinal lines parallel to traffic flow as shown in Figure 3B-19. For hard copies of documents with publication numbers, please send a request toreport.center@dot.govand include the publication number and title, along with the number of copies and your mailing address and phone number. w%h-HoV{..!`5wVl_, >,1@__~<0mno?lo_}wd2nG#oC?Ey,?7pnTA0. Directional configurations also should be used to avoid confusion resulting from visibility of markers that do not apply to the road user. A wide dotted white lane line shall be used: Lane drop markings used in advance of lane drops at freeway and expressway exit ramps should begin at least 1/2 mile in advance of the theoretical gore. Support: Figure 3B-13 Examples of Line Extensions through Intersections. Guidance: Where the distance between successive no-passing zones is less than 400 feet, no-passing markings should connect the zones. 07 Edge line markings may be used where edge delineation is desirable to minimize unnecessary driving on paved shoulders or on refuge areas that have lesser structural pavement strength than the adjacent roadway. Standard: If used, stop and yield lines should be placed a minimum of 4 feet in advance of the nearest crosswalk line at controlled intersections, except for yield lines at roundabouts as provided for in, Stop lines at midblock signalized locations should be placed at least 40 feet in advance of the nearest signal indication (see, 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, 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. 03 When crosshatch markings are used in paved areas that separate opposing directions of traffic, they shall be yellow diagonal markings that slant away from traffic in the adjacent travel lanes, as shown in Figures 3B-2 and 3B-5 and Drawings A and B of Figure 3B-15. Letters and numerals should be 6 feet or more in height.

Rural arterials and collectors with a traveled way of 20 feet or more in width and an ADT of 3,000 vehicles per day or greater. Figure 3B-25 Examples of Elongated Route Shields for Pavement Markings. Special Provision for Temporary Pavement Marking. Center line markings should also be placed on other traveled ways where an engineering study indicates such a need. For roadways where the posted or statutory speed limit is less than 45 mph, the formula L = WS2/60 should be used to compute the taper length. endstream endobj 81 0 obj <>stream 05 The upstream end of a no-passing zone at point "a" in Figure 3B-4 is that point where the sight distance first becomes less than that specified in Table 3B-1. 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). The space between the triangles should be 3 to 12 inches. Symbol messages are preferable to word messages. 17 Staggered stop lines and staggered yield lines can improve the driver's view of pedestrians, provide better sight distance for turning vehicles, and increase the turning radius for left-turning vehicles. All dimensions are in inches (millimeters)unless otherwise shown. For roadways where the posted or statutory speed limit is less than 45 mph, the formula L = WS2/60 should be used to compute the taper length. It is normally placed 4-inch either to the right or to the left of the geometric center of the roadway. If used, the diagonal or longitudinal lines should be 12 to 24 inches wide and separated by gaps of 12 to 60 inches. This guide seeks to establish materials sampling and testing uniformity throughout the state by providing sampling schedules which list the minimum frequencies at which samples and measurements shall be taken by project, plant, and IDOT's district personnel.This guide applies to all projects constructed on the state system and all local agency improvement projects with federal, state, or MFT funds. 10 Section 11-307 of the "Uniform Vehicle Code (UVC)" contains further information regarding required road user behavior in no-passing zones.

These drawings show the details of various construction items and are used in conjunction with the Standard Specifications. 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. 18 The International Symbol of Accessibility parking space marking (see Figure 3B-22) should be placed in each parking space designated for use by persons with disabilities. When diagonal or longitudinal lines are used to mark a crosswalk, the transverse crosswalk lines may be omitted. This type of marking may be used at locations where substantial numbers of pedestrians cross without any other traffic control device, at locations where physical conditions are such that added visibility of the crosswalk is desired, or at places where a pedestrian crosswalk might not be expected. Directions for unsubscribing are included with each email notification. These details will be updated on a continuous basis. Anyone, 5 years of age and older, is eligible to receive the COVID-19 vaccine. The yield-ahead triangle symbol or YIELD AHEAD word pavement marking shall not be used unless a YIELD sign (see, The International Symbol of Accessibility parking space marking (see, A blue background with white border may supplement the wheelchair symbol as shown in. 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. 01 Edge line markings shall be placed on paved streets or highways with the following characteristics: Guidance: %PDF-1.6 % Contract Detail - Illinois Figure 3B-9 Examples of Dotted Line and Channelizing Line Applications for Entrance Ramp Markings. Pavement Marking Selection, Installation and Inspection Manual Guidance: 12 On narrow, low-speed shared-use paths, the pavement words, symbols, and arrows may be smaller than suggested, but to the relative scale. 05 Blue raised pavement markers are sometimes used in the roadway to help emergency personnel locate fire hydrants. Figure 3B-5 Example of Application of Three-Lane, Two-Way Marking for Changing Direction of the Center Lane. The bidirectional marker is capable of displaying the applicable color for each direction of travel. 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; or. Edge line markings may be placed on streets and highways with or without center line markings. 05 Local highway agencies may prescribe special colors for curb markings to supplement standard signs for parking regulation. 18 Section 3B.20 contains information regarding other markings that are associated with lane drops, such as lane-use arrow markings and ONLY word markings. 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. Option: The pliant polymer pavement markings shall consist of a mixture of high-quality polymeric materials, pigments and glass beads distributed throughout its base cross-sectional area, with a layer of wet retroreflective media bonded to a durable polyurethane topcoat surface. Option: 02 If used, speed reduction markings should be reserved for unexpected curves and should not be used on long tangent sections of roadway or in areas frequented mainly by local or familiar drivers, (e.g., school zones). Where it is desired to alert the road user to changes in the travel path, such as on sharp curves or on transitions that reduce the number of lanes or that shift traffic laterally, the spacing may be reduced to N or less. 05 Speed reduction markings shall not be used in lanes that do not have a longitudinal line (center line, edge line, or lane line) on both sides of the lane. .

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 Figure 3B-29. 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. Special Provisions | Lake County, IL Support: 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. ROADWAY SIGNING AND PAVEMENT MARKING GUIDELINES MARCH 2021 | ILLINOIS TOLLWAY | 2 19. 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. When supplementing line extensions through freeway interchanges, a spacing of no greater than N should be used. If a pavement marking word message consists of more than one line of information, it should read in the direction of travel. 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. At non-intersection locations, crosswalk markings legally establish the crosswalk. Option: 07 Yield lines (see Figure 3B-16) shall consist of a row of solid white isosceles triangles pointing toward approaching vehicles extending across approach lanes to indicate the point at which the yield is intended or required to be made. ?~$_}'gz#/\A Q$V[RDoQW9 (~W??>\r?(?^}u#O?J|]f/ When the final pavement marking plan sheets are placed into the construction plans, all variables should be determined and entered directly on the sheet(s), and all designer, Files available in Microstation format (DGN) or Adobe Reader format (PDF), Please report any errors or suggested changes to the Pavement Marking Engineer at. A lane-reduction transition (see Section 3B.09) shall be provided at each end of the buffer zone. Where the curbs of the islands become parallel to the direction of traffic flow, it is not necessary to mark the curbs unless an engineering study indicates the need for this type of delineation. Guidance: 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. 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.

Speed measurement markings may extend 24 inches on either side of the center line or 24 inches on either side of edge line markings at 1/4-mile intervals over a 1-mile length of roadway. 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. 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. 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. areas, aggregate shoulders, temporary pavement marking, recessed reflective pavement marking, and other items to complete the project. Navigate to Erosion and Sediment Control for more information in regards to methods to prevent soil and other pollutants from leaving the construction site. When supplementing dotted lane line markings, a spacing appropriate for the application should be used. If a traffic count is not available, the ADTs described in this Section may be estimates that are based on engineering judgment. In the absence of a marked crosswalk, the stop line or yield line should be placed at the desired stopping or yielding point, but should not be placed more than 30 feet or less than 4 feet from the nearest edge of the intersecting traveled way. 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. 21 Where it is intended to discourage lane changing on the approach to an exit ramp, a wide solid white lane line may extend upstream from the theoretical gore or, for multi-lane exits, as shown in Drawing B of Figure 3B-10, for a distance that is determined by engineering judgment. If used, speed reduction markings should supplement the appropriate warning signs and other traffic control devices and should not substitute for these devices. 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, The upstream end of a no-passing zone at point "a" in, The values of the minimum passing sight distances that are shown in Table 3B-1 are for operational use in marking no-passing zones and are less than the values that are suggested for geometric design by the AASHTO Policy on Geometric Design of Streets and Highways (see.
