Center for Weather Impacts on Mobility and Safety

Motorists have high expectations that roads will be cleared of snow and ice quickly.

Formed in 2005, CWIMS is focused on finding better and safer ways to travel whenever weather is a problem.

Research Projects

The concept maintenance vehicle was a multi-state, multi-phase project that evaluated several different technologies related to winter maintenance.

Iowa State students worked with the Iowa Department of Transportation to gather data on bridge frost, a safety hazard to motorists.

Aurora

InTrans 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.
