• Abstract:
  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.
