... Among the more detailed designs, layout details, and associated practices that are found in many of the state and local documents are: • Methods of delineating turn lane channelization, • Patterns and spacing of lane-use turn arrows and ONLY word markings, • Patterns and spacing of crosswalk markings and stop lines, • Patterns and spacing of turn arrows in two-way left-turn lanes, • Patterns and dimensions of chevrons and diagonal lines, • Methods of delineating climbing and passing lanes, and • Methods of delineating entrance ramp and exit ramp gores. The purpose of this synthesis was to identify variations in pavement marking designs, practices, and policies of each state department of transportation (DOT)

... Chapter two details the pavement markings associated with intersections, including lane lines, turn arrows, and ONLY word markings in turn lanes, dual turn lanes, and dropped lanes; dotted lines in turn lane tapers; crosswalks; stop lines; formation of left-turn lanes between the through lanes on twolane highways; and right-turn channelizing islands. Chapter three reviews the pavement markings associated with sections of streets and highways between intersections, including midblock crosswalks; passing and no-passing zones; two-way left-turn lanes; climbing and passing lanes; lane reductions; and painted medians, paved shoulders, and approaches to obstructions.
