MedianAlert™ Visibility Enhancement

The MedianAlert™ is designed to dramatically improve the nighttime visibility of medians and other roadway structures.  A flexible, elongated retroreflective device that visually alerts the motorist of the structure’s presence as well as a clear and concise message of its size and shape.

Medians and other fixed structures are used in the roadway system for lane division and access control. Such roadway structures, if not adequately visible to the motorist, can potentially present hazards to both motorists and pedestrians.
