Title: NEW JERSEY GUIDE-SIGN SURVEY
Accession Number: 00621444
Record Type: Component
Availability: Find a library where document is available Abstract: As part of a study to review difficulties of drivers in viewing large guide signs, or "interferences," on state highways in New Jersey, a survey from a fast-moving automobile was performed. The survey covered more than 1,000 approaches to interchange exits in the 2,000-mi New Jersey system. More than 580 motorist view interferences were discovered through visual observations. The method was verified to be 94% accurate using a videotape method and a legibility formula with a sample of approaches. Sign view blockage by difficult- and expensive-to-modify highway features and furniture represented 35% of the interferences. Computer graphic interchange modeling at an earlier design stage is recommended to help avoid view blockages in the future.
