AN EVALUATION OF EXPANDED METAL GLARE SCREEN ON THE NEW JERSEY CONCRETE MEDIAN BARRIER

This report is an evaluation of the experimental use of expanded metal mesh as a glare screen. The installation consisted of several types of mesh of slightly varying heights mounted on the concrete median barrier, Route 22, Scotch Plains, New Jersey. A description of the designs, methods of installation, observation and accident statistics are presented. Nighttime observations supported by motion pictures demonstrate the reduction in headlight glare while favorable letters sent to the department by motorists attest to the increased driving comfort level. The decrease in the nighttime accident rate although of weak statistical significance indicates that the glare screen is effective in reducing accidents. The glare screen did not act as a snow fence or collect litter nor was it damaged by loose tarps, ropes, etc. Although two systems are available for immediate implementation another installation of greater magnitude for comparative analysis is recommended before incorporation into the standard construction details. It further recommends development of warrants for the placement of glare screening for medial or other locations. /FHWA/
