Where a lane-reduction transition occurs on a roadway with a speed limit of 45 mph or more, the lane-reduction arrow markings shown in Drawing f in. 02 The spacing for such applications should be 2N, where N equals the length of one line segment plus one gap (see Section 3B.11). 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.

The bidirectional marker is capable of displaying the applicable color for each direction of travel. Guidance: Standard: The word STOP shall not be placed on the pavement in advance of a stop line, unless every vehicle is required to stop at all times. The longitudinal spacing of the chevrons or diagonal lines should be determined by engineering judgment considering factors such as speeds and desired visual impacts. DOC Temporary Pavement Marking The manual is organized similar to the Standard Specifications. 10 For entrance ramps with a parallel acceleration lane, a normal width dotted white lane line shall be installed from the theoretical gore or from the downstream end of a solid white lane line, if used, that extends downstream from the theoretical gore, to a point at least one-half the distance from the theoretical gore to the downstream end of the acceleration taper, as shown in Drawing A of Figure 3B-9. )V01|rssS!ny%!Ayy)yyyp~piRIeA~0 vv )L 24 An arrow at the downstream end of a turn lane can help to prevent wrong way movements.

Lane-use arrow markings should also be used in lanes from which movements are allowed that are contrary to the normal rules of the road (see Drawing B of Figure 3B-13). This supplement is intended for use when the Construction and Materials Management System (CMMS) is being utilized to administer a construction contract. To the extent possible, pavement marking extensions through intersections should be designed in a manner that minimizes potential confusion for drivers in adjacent or opposing lanes. Guidance: Special Provisions | Lake County, IL Standard: 02 Edge line markings should be placed on paved streets or highways with the following characteristics: 03 Edge line markings should not be placed where an engineering study or engineering judgment indicates that providing them is likely to decrease safety. An arrow at the downstream end of a turn lane can help to prevent wrong way movements. Center line pavement markings may be placed at a location that is not the geometric center of the roadway. 04 Pavement marking letters, numerals, symbols, and arrows shall be installed in accordance with the design details in the Pavement Markings chapter of the "Standard Highway Signs and Markings" book (see Section 1A.11). A channelizing line shall be a wide or double solid white line. 14 When diagonal or longitudinal lines are used to mark a crosswalk, the transverse crosswalk lines may be omitted. Option: The individual triangles comprising the yield line should have a base of 12 to 24 inches wide and a height equal to 1.5 times the base. 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: The diagonal markings shall be white when used on right-hand shoulders.
