One of the chief factors contributing to nighttime accidents is headlight glare. 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 design, methods of installation, observation and accident statistics are presented. Nighttime observations supported by motion pictures demonstrate the reduction in headlight glare. the decrease in the nighttime accident rate although of weak statistical significance indicates that the glare screen is effective in reducing accidents.
