Abstract:

The Wisconsin Department of Transportation (WisDOT) has created its own customized weather information system to improve efficiency in its winter road maintenance operations. Intended to help contractors decide when to spread salt or anti-icing methods, the roadway weather information system (RWIS) is also useful for helping summer work crews decide when to mark pavement, pour concrete or perform other weather-sensitive tasks. The RWIS consists of a weather forecast and animated weather radar picture delivered via the Internet and satellite to all contractors. The forecast is updated continuously, so users can track weather developments easily. Pavement temperature sensors, some of which are mounted in permanent positions around the state and some of which are strapped to road supervisors' vehicles, supplement the weather forecast with information about actual road conditions.
