BEST PRACTICE:

G4-21: Glare Screen Systems

DESCRIPTION:

Glare screen systems are vertical blades used to clearly mark both temporary and permanent medians as well as block out headlight glare from oncoming traffic during night time applications. These devices are made of polymeric materials designed to fit into a base rail system positioned on top of median barriers.

REASON(S) FOR ADOPTING:

Glare screens serve as a guiding marker, enhancing visibility of the median and helping to create a clear path of travel for motorists. These devices help reduce traffic jams in work zones by limiting cross-median visibility while providing fast and easy installations

PRIMARY BENEFIT(S):

The screen systems obscure the view of construction work to reduce rubbernecking. They may be made from recycled materials and are easily mounted to both concrete median barriers and steel guardrail systems. The lightweight plastic materials also serve as a deterrent for pedestrian cross-overs and protect debris from entering the work zone.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Screen systems are typically used in the median of divided highways but may be used in other applications where a specific problem exists or is anticipated. Depending on the State, glare screen use is justified based on traffic volumes and median widths in unlighted sections, and based on traffic volumes and the number of lanes in lighted sections.

STATE(S) WHERE USED:

California , Iowa, Michigan, New Jersey, New York, Ohio, Pennsylvania, Vermont, Virginia
