Abstract:The durability of delineators should be considered when selecting a product. Looking at the data
gathered in this project, there was a considerable gap between the quality of the top three delineators tested
and the other four. This led the researchers to recommend minimum average numbers of 150 tire impacts and
45 bumper impacts resisted as a pass/fail criterion for managed lane marker durability. This criterion would
serve as a reasonable requirement ensuring that quality products meet a minimum threshold of performance.
As the values are based on product testing, it ensures the criterion is an obtainable value for companies who
intend to market their product for this application.
The researchers developed a minimum requirement specification to ensure compliance according to
the recommendations found within this report. This specification will help to ensure that the proper and more
durable product is selected to be placed on Florida Department of Transportation roadways.
