Major construction projects present many hazards for drivers to negotiate. Detours, lane shifts and confusing curves present unique challenges to all drivers. At night, the difficulties in negotiating these obstacles are amplified due to reduced visibility. Over the past several years, the Oregon Department of Transportation has been particularly interested in evaluating concrete barrier marking products the improve the delineation of lane shifts, sharp turns, and detours within highway work zones. This project evaluated the installation, maintenance and effectiveness of the 3M Scotchlite Linear Delineation System (LDS) mounted on concrete barriers within three different highway work zones. The installation of the LDS panels proved to be more challenging then envisioned, primarily because installation is a time intensive process. Users need to be aware of the productivity rates for installation. A maintenance concern with the panels is to keep them relatively clean from dirt and road grime to maintain an optimal level of retroreflectivity. The LDS panels provide a good alternative to traditional concrete barrier delineation methods (such as reflective barrier markers). At the end of construction, panels can be removed from the barrier and reused on future projects. The success of the panels has led ODOT to consider further implementation on future construction projects, as well as permanent installation in areas where crash histories warrant additional safety measures.
