WeatherBrain is a software package that produces readable meteorological data for predicting road and weather conditions, allowing more efficient use of road crews.

Campbell Scientific said that WeatherBrain’s forecasting, analysis and decision support capabilities can save users time, money and effort on their winter road maintenance programmes.

For the year-long test in Magog, in the province of Quebec, Campbell Scientific covered the city’s 550km of roads with a myriad of weather stations. Individually, these stations act as traditional road weather information systems – RWIS – to monitor snow thickness both on and off roadways. They also collect data on air temperature and dew point.

The problem with traditional RWIS stations is that they collect meteorological data about current conditions via road surface and atmospheric sensors and a datalogger. The datalogger compiles information gathered from the sensors, then delivers the often-cryptic piles of data to the end-user for their analysis and interpretation.

WeatherBrain stations are different, according to Campbell Scientific, because they collate, analyse and present the data in much more detail and in a more easily understood format than traditional stations. Collectively, WeatherBrain’s stations make up a densified network of data points.

An inability to accurately interpret meteorological data remains can result in the over-use and misuse of road salts to prevent accidents.

Similar to traditional RWIS, WeatherBrain consists of a series of RWIS stations equipped with sensors to monitor snow thickness, air temperature, dew point and other facts. However, WeatherBrain has the capacity to pull in geo-relevant third party data, providing a more robust data set to allow for increased relevancy and accuracy.

Extensive algorithms take this geo-relevant data set and create nowcasts and forecasts for the next 12 hours. Based on these nowcasts and forecasts, the software produces actionable indicators that show the user when they’ll need to take action, effectively putting them ahead of impending weather events.

For example, based on the systems forecast, Campbell Scientific said that WeatherBrain can predict a black ice event will occur in 4 hours, so road maintenance operators can schedule their road crews to take proactive maintenance, eliminating the risk altogether.
