Pavement Markings -- Design and Typical Layout Details

This synthesis identifies variations in pavement marking designs, practices, and policies, as provided by 48 of 50 state departments of transportation, and transit agencies from the District of Columbia, Puerto Rico and four cities. This information will be valuable to FHWA and the National Committee on Uniform Traffic Control Devices as they consider the need for revisions to the 2008 edition of Part 3 of the Manual on Uniform Traffic Control Devices. In addition, the information will be useful to state and local government agencies as they develop or revise their pavement marking design standards. This synthesis does not specifically address the safety aspects or cost-effectiveness of the pavement marking layout policies and practices of the various agencies.
