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 practice-ready policies, processes, tools, and products that enhance the implementation and constructability, safety, and mobility impacts of all types of work zones. In 2001, Wisconsin joined the MwSWZDI consortium.
The project is part of the Transportation Pooled Fund Program, Study Number TPF-5(295). 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. SWZDI has a 15-year proven track record of funding useful work zone-related research and outreach products that has resulted in more than 80 studies, evaluations, and syntheses.
