About SWZDI

In 1999, the states of Iowa, Kansas, Missouri, and Nebraska created the Midwest States Smart Work Zone Deployment Initiative (MwSWZDI).

Through this pooled-fund study, researchers investigate better ways of controlling traffic through work zones. Their primary objective is to promote and support research and outreach activities that focus on innovative policies, processes, tools, and products that enhance the implementation, safety, and mobility impacts of work zones. In 2001, Wisconsin joined the MwSWZDI consortium.

The project is part of the Federal Highway Administration (FHWA) Transportation Pooled Fund Program, Study Number TPF-5(438). The name has changed slightly by dropping “Midwest” from the title. The project is now administered by Iowa State University’s Institute for Transportation. The lead agency is the Iowa Department of Transportation. For more than 20 years, SWZDI has had a proven track record of funding useful work zone-related research and outreach products that has resulted in more than 90 studies, evaluations, and syntheses. In 2020, Illinois, Michigan, and Texas joined the consortium. In 2022, Minnesota also joined the consortium.
