Abstract:This research was conducted to assist the Michigan Department of Transportation in assessing the State’s
current delineation program. Opus International Consultants (Opus) and Western Michigan University
(WMU) were retained to undertake this review and analysis, including a review of existing literature and
current state-of-the-art, a delineation survey with follow-up of state and Canadian provinces, and finally
a benefit-cost and alternatives analysis to consider potential changes to MDOT’s existing program. In the
Michigan context, statistical analysis shows potential benefits for wider adaptation of polyurea pavement
markings, snowplowable raised pavement markers on high-AADT roadways, and freeway lighting at
interchanges.
