RWIS stands for Road Weather Information System. It is a network of sensors and data processing equipment designed to monitor weather and road conditions. These systems provide real-time information to transportation agencies and the public about factors that can affect travel, such as temperature, precipitation, pavement conditions, and visibility. RWIS stations are typically installed along major roadways and highways.

The data collected by RWIS helps traffic engineers and maintenance crews make informed decisions. This includes determining when and where to deploy snowplows and de-icing equipment, managing traffic flow during adverse weather, and issuing weather-related advisories to travelers. The information is often disseminated through highway signs, websites, and mobile applications.

The primary goal of RWIS is to enhance transportation safety and efficiency, especially during challenging weather events. By providing accurate and timely data, RWIS contributes to reducing accidents, minimizing travel delays, and improving overall traffic management. The system's infrastructure can include various sensors like pavement temperature sensors, moisture detectors, and atmospheric sensors, all feeding into a central data processing hub.
