Abstract

The report presents the findings of field studies revealed that as sight distance to a lane closure decreases, more and more drivers are "trapped" in the closed lane at the taper area. Also, sight distance is more critical as traffic volumes increase. Based on the study findings, a minimum desirable sight distance of 1500 feet was recommended for lane closure work zones on freeways. Arrow boards were found to be effective traffic control devices for lane closures where the sight distance is adequate.
