Work Zone Materials for Temporary Signs in High Wind Areas

As part of TxDOT staying in compliance with the Code of Federal Regulations, 23 CFR 630.1008, the Traffic Control Review Team (TCRT) reviews work zone traffic control devices in work zones throughout all 25 districts each fiscal year. One of the most common problems encountered on reviews is temporary signs being knocked down because of wind. This is due to ineffective ballast materials and techniques. Sand bags are often used to ballast temporary signs, but this technique with the current materials needs improvement to be more reliable and effective. Temporary signs that are knocked down and not visible to the traveling public increase the risk of tort liability. This is a greater problem in areas of the state with high winds. Also, the longer a temporary sign is up during a project, the more likely it is for it to fall down due to wind. This research will evaluate other techniques and materials to reduce temporary signs from falling over due to high winds. This research will also evaluate other possible mitigation measures for temporary signs in areas with high winds or on projects based on work zone durations. Costs and other implications of alternative methods for installing temporary signs in work zones in areas with high winds will be evaluated.
