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, Solid white lane line markings may be used to separate through traffic lanes from auxiliary lanes, such as an added uphill truck lane or a preferential lane (see. Option: Standard: If used, speed reduction markings should supplement the appropriate warning signs and other traffic control devices and should not substitute for these devices. 05 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. 05 Raised pavement markers should not substitute for right-hand edge line markings 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 line is close enough to avoid misinterpretation as a broken line during wet night conditions. Standard: Please continue to check for addenda. Engineering judgment should be used in determining whether to place center line markings on traveled ways that are less than 16 feet wide because of the potential for traffic encroaching on the pavement edges, traffic being affected by parked vehicles, and traffic encroaching into the opposing traffic lane. The UVC can be obtained from the National Committee on Uniform Traffic Laws and Ordinances at the address shown on Page i. 10 If traffic can pass either to the right or left of the obstruction, additional white chevron crosshatch markings (see Section 3B.24) may be placed in the flush median area between the channelizing lines as shown in Drawing C of Figure 3B-15.

A lock ( LockA locked padlock ) or https:// means youve safely connected to the .gov website. An engineering study should be performed before a marked crosswalk is installed at a location away from a traffic control signal or an approach controlled by a STOP or YIELD sign. Option: Among the word, symbol, and arrow markings that may be used are the following: Standard: 01 Marking of parking space boundaries encourages more orderly and efficient use of parking spaces where parking turnover is substantial. Edge line markings should not be broken for minor driveways. Specific exceptions to this Manual for Local Agency work are indicated in the current Local Roads and Streets Manual(s) or by circular letter. The applicable Standards are referenced on the cover sheet of the plans. 07 If traffic is required to pass only to the right of the obstruction, the markings shall consist of a two-direction no-passing zone marking at least twice the length of the diagonal portion as determined by the appropriate taper formula (see Drawing A of Figure 3B-15). ?~$_}'gz#/\A Q$V[RDoQW9 (~W??>\r?(?^}u#O?J|]f/ The first word of the message should be nearest to the road user. In Chicago, the typical roadway pavement width for a large proportion of local streets is 30 feet, measured from face of curb to face of curb. 02 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. The roadway has four or more lanes of travel with a raised median or pedestrian refuge island and an ADT of 15,000 vehicles per day or greater.
