Pavement Markings State-of-the-Practice Study

摘要

Longitudinal pavement markings are used to delineate the limits of a travel lane, convey regulations or warnings, provide guidance to road users, and/or supplement other traffic control devices. The Pennsylvania Department of Transportation is interested in identifying pavement marking products, practices, and 'lessons learned' in other states with climates and winter maintenance activities similar to those found in Pennsylvania. The Department executed an agreement with the Thomas D. Larson Pennsylvania Transportation Institute at Penn State to perform research in this area to learn more about pavement marking practices. The goal of this research was to draw on the successes and failures of other states to improve Pennsylvania's pavement marking program. This research report documents pavement marking practices in 19 other states and the solutions these states have developed and implemented to improve the visibility and useful life of pavement markings. This report includes a matrix that details the current state-of-the-practice in state pavement marking programs.
