Temporary Pavement Markings Placement and Removal Practices in Work Zones

The use of temporary pavement markings in work zones helps delineate the vehicle path of travel and direct drivers safely through various work zone configurations such as lane changes, alignment shifts, and crossovers. The objective of this synthesis was to review and document the policies and processes used by state departments of transportation (DOTs) for placement, maintenance, and removal of pavement markings in work zones. The synthesis report documents information such as frequency of use; design considerations; performance; innovative DOT practices; and DOT policies, standards, and specifications. Information in this study was acquired through a review of the literature, a survey of representatives of DOTs, and follow-up interviews with seven states.This synthesis has identified some gaps in existing knowledge and future research needs to enhance practices for temporary pavement markings in work zones and pavement marking removal methods in the United States.
