Guidance: 01 Chevron and diagonal crosshatch markings may be used to discourage travel on certain paved areas, such as shoulders, gore areas, flush median areas between solid double yellow center line markings or between white channelizing lines approaching obstructions in the roadway (see Section 3B.10 and Figure 3B-15), between solid double yellow center line markings forming flush medians or channelized travel paths at intersections (see Figures 3B-2 and 3B-5), buffer spaces between preferential lanes and general-purpose lanes (see Figures 3D-2 and 3D-4), and at grade crossings (see Part 8). See Section 3B.20 for provisions regarding use of lane-reduction arrows. Stop lines should be used to indicate the point behind which vehicles are required to stop in compliance with a traffic control signal. 04 If used, right edge line pavement markings shall consist of a normal solid white line to delineate the right-hand edge of the roadway. Other pavement markings in the channelizing island area shall be white. 02 Center line pavement markings may be placed at a location that is not the geometric center of the roadway. Center line markings should also be placed on other traveled ways where an engineering study indicates such a need. %%EOF Fact Sheet: Rumble Strips and Pavement | FHWA When supplementing longitudinal line extension markings through at-grade intersections, one raised pavement marker for each short line segment should be used. endstream endobj 6 0 obj <> endobj 7 0 obj <> endobj 8 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/Type/Page>> endobj 9 0 obj <>stream Non-retroreflective raised pavement markers should not be used alone, without supplemental retroreflective or internally illuminated markers, as a substitute for other types of pavement markings. Pavement Markings - INDOT Because of the low approach angle at which pavement markings are viewed, transverse lines should be proportioned to provide visibility at least equal to that of longitudinal lines. 06 Channelizing lines at entrance ramps as shown in Figures 3B-9 and 3B-10 promote orderly and efficient merging with the through traffic. Standard: On narrow, low-speed shared-use paths, the pavement words, symbols, and arrows may be smaller than suggested, but to the relative scale. 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. As of January 1, 2006, all design approvals will be based on the most current electronic version of this manual unless a variance is granted. The longitudinal spacing of the chevrons or diagonal lines should be determined by engineering judgment considering factors such as speeds and desired visual impacts.

Highway Standards & District Specific Standards These drawings show the details of various construction items and are used in conjunction with the Standard Specifications. The spacing for such applications should be 2N, where N equals the length of one line segment plus one gap (see. Phone # E-Mail. 0 Similarly, the passing sight distance on a horizontal curve is the distance measured along the center line (or right-hand lane line of a three-lane roadway) between two points 3.5 feet above the pavement on a line tangent to the embankment or other obstruction that cuts off the view on the inside of the curve (see Figure 3B-4). Guidance: The minimum taper length should be 100 feet in urban areas and 200 feet in rural areas. Where curbs are marked to convey parking regulations in areas where curb markings are frequently obscured by snow and ice accumulation, signs shall be used with the curb markings except as provided in. 05 If transverse lines are used to mark a crosswalk, the gap between the lines should not be less than 6 feet. Pavement Markings Regulations / Standards | FHWA Guidance: If authorized by law, Do Not Block Intersection markings with appropriate signs may also be used at other locations. 06 The center line markings on undivided two-way roadways with four or more lanes for moving motor vehicle traffic always available shall be the two-direction no-passing zone markings consisting of a solid double yellow line as shown in Figure 3B-2. Standard: 27 On freeways or expressways where a through lane becomes a mandatory exit lane, lane-use arrow markings may be used on the approach to the exit in the dropped lane and in an adjacent optional through-or-exit lane if one exists. 29 Wide solid lane line markings may be used for greater emphasis. NOT FINDING WHAT YOU NEED? Curbs at openings in a continuous median island need not be marked unless an engineering study indicates the need for this type of marking. The CMMS Supplement Documentation of Contract Quantities Guide document serves as a supplement to the departments Documentation of Contract Quantities Guide. 21 Lane-use arrow markings (see Figure 3B-24) should be used in lanes designated for the exclusive use of a turning movement, including turn bays, except where engineering judgment determines that physical conditions or other markings (such as a dotted extension of the lane line through the taper into the turn bay) clearly discourage unintentional use of a turn bay by through vehicles. Standard: A lane-reduction transition (see Section 3B.09) shall be provided at each end of the buffer zone. 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. The space between the triangles should be 3 to 12 inches. 12 For entrance ramps with a tapered acceleration lane, a normal width dotted white line extension may be installed from the downstream end of the channelizing line adjacent to the through lane to the downstream end of the acceleration taper, as shown in Drawings B and C of Figure 3B-9. %PDF-1.6 % endstream endobj 78 0 obj <> endobj 79 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 0/Type/Page>> endobj 80 0 obj <>stream 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. 01 If used, edge line pavement markings shall delineate the right or left edges of a roadway. If an addendum is posted, the contract details above may be revised. 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. A channelizing line shall be a wide or double solid white line. The centerline markings on undivided two-way roadways with four or more lanes for moving motor vehicle traffic shall be the two-direction no-passing zone markings consisting of a solid double yellow line separated by 4 in.
