In-Service Evaluation of Temporary Sign Support Systems Against Wind Load

The Illinois Department of Transportation and industry partners have worked together for over five years in the transition to the use of MASH-compliant temporary traffic control devices. As a result of a sunset date established in 2019, the use of MASH-compliant temporary sign supports in work zones is increasing. Industry, however, is uncertain about the in-field performance and potential safety concerns associated with sign stability, particularly due to wind loads. Researchers will evaluate the rigidity, stability and feasibility of temporary signs stands’ use for construction as well as quantify the impacts of wind. IDOT will use the findings to determine which temporary sign support systems will be allowed, ensuring there are no unintended risks associated with in-service performance or increased worker exposure associated with sign deployment and maintenance.
