Center for Weather Impacts on Mobility and Safety
CWIMS is a new center, formed in 2005, that's focused on finding better and safer ways to travel whenever weather is a problem. Faculty and staff at CTRE and Iowa State University have conducted research and technology transfer activities in this field for several years. Our capabilities are extensive and diverse.
Motorists have high expectations that roads will be cleared of snow and ice quickly.

Related Programs
Aurora
CTRE administers the Aurora program, an international pooled-fund partnership for research in road weather information systems. See "Go Light with the Salt, Please: Developing Information Systems for Winter Roadway Safety" in the January–February 2004 edition of TR News (pdf) for an article about Aurora.
Iowa Environmental Mesonet
The Iowa Environmental Mesonet (IEM) was established and maintained as a partnership between Iowa State University, the Iowa Department of Transportation, the National Weather Service, and KCCI, the CBS affiliate television station in Des Moines, Iowa. (The IEM won a national award for being a public-private-university partnership.) The IEM displays a variety of raw and derived products using RWIS data. The Iowa DOT has played a central role in the RWIS data collection.
Weather Issues in Transportation
Led by the Iowa DOT, a diverse group of researchers is developing a regional, multi-disciplinary approach to establishing a weather-related research and technology transfer program. Read more about it on the Weather Issues in Transportation website.
