PAVEMENT MARKING TAPE, TYPE IV 8" Base items 78000100 . 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. 02 In conjunction with signs and other measures, crosswalk markings help to alert road users of a designated pedestrian crossing point across roadways at locations that are not controlled by traffic control signals or STOP or YIELD signs. If advance markings are used, they shall comply with the detailed design shown in Figure 3B-31. 13 If a traffic count is not available, the ADTs described in this Section may be estimates that are based on engineering judgment.
Standard:
06 Solid lines shall not be used to extend edge lines into or through intersections or major driveways. @L
Section 11-307 of the "Uniform Vehicle Code (UVC)" contains further information regarding required road user behavior in no-passing zones. 9. 01 When used, lane line pavement markings delineating the separation of traffic lanes that have the same direction of travel shall be white. The diagonal markings shall be white when used on right-hand shoulders.

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. IDOTs Bureau of Design and Environment (BDE) issues the BDE Special Provisions four times a year. 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. Examples of standard word and arrow pavement markings are shown in Figures 3B-23 and 3B-24. Option:
If you would like to purchase a Manual, please visit our Manual Sales page. 27 Where the median width allows the left-turn lanes to be separated from the through lanes to give drivers on opposing approaches a less obstructed view of opposing through traffic, white pavement markings may be used to form channelizing islands as shown in Figure 2B-17. 13 A wide dotted white lane line shall be used: Figure 3B-10 Examples of Applications of Freeway and Expressway Lane-Drop Markings, Figure 3B-11 Examples of Applications of Conventional Road Lane-Drop Markings. 08 If traffic is required to pass only to the right of the obstruction, yellow diagonal crosshatch markings (see Section 3B.24) may be placed in the flush median area between the no-passing zone markings as shown in Drawings A and B of Figure 3B-15. Discontinuation of the Use of Fog Seals The space between the triangles should be 3 to 12 inches. The applicable Standards are referenced on the cover sheet of the plans. On roadways with center line markings, no-passing zone markings shall be used at horizontal or vertical curves where the passing sight distance is less than the minimum shown in Table 3B-1 for the 85th-percentile speed or the posted or statutory speed limit.

03 At non-intersection locations, crosswalk markings legally establish the crosswalk. Option:
Support:
areas, aggregate shoulders, temporary pavement marking, recessed reflective pavement marking, and other items to complete the project. 05 Where greater restriction is required, solid lane lines or channelizing lines should be extended into or continued through intersections or major driveways. 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. 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. 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. 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. To view the most current DGN files please navigate to Highways Standards. 08 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.
Highway Standards & District Specific Standards Retroreflective solid white markings should be used when traffic is permitted to pass on either side of the island.
Idaho Transportation Department The number of different word and symbol markings used should be minimized to provide effective guidance and avoid misunderstanding. Option:
Where lane changes might cause conflicts, a wide or normal solid white lane line may extend upstream from an intersection. The following is a listing of pay item unit of measure to material code unit conversion factors in pay item order. Two-direction passing zone markings consisting of a normal broken yellow line where crossing the center line markings for passing with care is permitted for traffic traveling in either direction; One-direction no-passing zone markings consisting of a double yellow line, one of which is a normal broken yellow line and the other is a normal solid yellow line, where crossing the center line markings for passing with care is permitted for the traffic traveling adjacent to the broken line, but is prohibited for traffic traveling adjacent to the solid line; or. Directional configurations should be used to maximize correct information and to minimize confusing information provided to the road user. 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. xref

Guidance:
However, when supplementing broken line markings identifying reversible lanes, a spacing of no greater than N should be used.
PDF NOTICE TO CONTRACTORS BULLETIN - idot.illinois.gov Guidance:
They shall not be less than 6 inches or greater than 24 inches in width. 07 Where curbs are marked for delineation or visibility purposes, the colors shall comply with the general principles of markings (see Section 3A.05). 06 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. On approaches to intersections, solid white lane line markings may be used to separate adjacent through lanes or adjacent mandatory turn lanes from each other.
Option:
SHORT TERM PAVEMENT MARKING Base items 70300150 . When drivers yield or stop too close to crosswalks that cross uncontrolled multi-lane approaches, they place pedestrians at risk by blocking other drivers' views of pedestrians and by blocking pedestrians' views of vehicles approaching in the other lanes. The bidirectional marker is capable of displaying the applicable color for each direction of travel. 06 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 Section 1A.11). Option:
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. Appropriate advance warning signs may be used in compliance with Section 2C.29. Center line pavement markings may be placed at a location that is not the geometric center of the roadway. 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. Where through lanes approaching an intersection become mandatory turn lanes, lane-use arrow markings (see, Where through lanes approaching an intersection become mandatory turn lanes, ONLY word markings (see. Figure 3B-9 Examples of Dotted Line and Channelizing Line Applications for Entrance Ramp Markings. 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. 25 On approaches to intersections, a solid white lane line marking should be used to separate a through lane from an added mandatory turn lane. 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. 04 To improve the visibility of horizontal curves, center lines may be supplemented with retroreflective or internally illuminated raised pavement markers for the entire curved section as well as for a distance in advance of the curve that approximates 5 seconds of travel time. 12 The buffer zone shall be a flush median island formed by two sets of double yellow center line markings that is at least 50 feet in length.
