Description: RWIS stands for Roadway Weather Information System. ODOT owns over 100 weather stations, which provide coverage in all 88 of Ohio’s counties. A central service located in Columbus processes the information from each station. ODOT garages use the information collected by the stations to plan their road treatment activities, especially during snow and ice. conditions. ODOT also makes road conditions available to the public via a Web server (www.buckeyetrafffic.org). The weather stations and sensors are located along interstates, U.S. routes, and state routes.
