Work Zone Safety

The Work Zone Safety Committee oversees work zone traffic safety issues that affect the traveling public and road workers within temporary traffic control zones. Areas of oversight include design policies, standard road plans, specifications, training, research, and new product evaluation as they relate to temporary traffic control zones. Committee members also conduct field reviews during the construction season to observe traffic control installations and recommend changes for future work zones.
