Abstract:This project evaluates the safety impacts, environmental impacts, and cost effectiveness of different pavement marking
systems as well as the effect of State bidding and procurement processes on the quality of pavement marking material
employed in highway projects. The findings indicate that States are pursuing alternative procurement strategies to provide
high-quality durable markings in a cost effective manner, often as part of a strategic safety plan, while industry has
responded to requirements for more environmentally benign materials. A multi-State retrospective crash analysis
suggests that the use of 6-inch edge lines reducesseveral crash types on rural two-lane two-way roads as compared to
4-inch edge lines. The monitored performance of pavement markings installed as part of the demonstration project
was used to evaluate pavement marking cost effectiveness. The same results were also used to populate a framework
for a pavement marking selection tool.
