Work Zone Lane Closure Warning Light System

摘要

This report has documented the research performed to assess the effectiveness of211u001ea flashing warning light system as a work zone traffic control device. 211u001eResearchers investigated motorist understanding of and perceived usefullness of 211u001evarious designs of the warning light system in a simulated work zone at night at 211u001eTTI's proving ground facility at the Texas A&M University Riverside Campus. Field 211u001estudies of the warning light system were also performed at night to determine if 211u001ethe system would yield significant operational or safety benefits in actual work 211u001ezone applications. Furthermore, researchers discussed the physical design of the 211u001ewarning light system in respect to the problems encountered while using the 211u001esystem in the proving ground and field studies.
