Road Weather Information Systems for Winter Road Maintenance

Road Weather Information System (RWIS) technology is a useful tool in evaluating road conditions in cold climates, and is helpful in optimizing the timing of salting/plowing procedures, as well as the quantity of salt used. RWIS technology is used as a means of improving the cost-effectiveness of winter road maintenance. Most agencies use RWIS data to predict winter storms that can justify snow and ice control, plowing, and chemical, salt, and sand operations. Agencies also use RWIS to predict weather for nighttime paving crews and also for legal issues when an operation is supposed to be done at a certain temperature. Using this information helps agencies to time out road repair jobs accordingly so that the job can be done in the least amount of time and also in the correct conditions for the materials to be applied in. Two models that are being analyzed are the Model of the Environment and Temperature of the Roads (METRo) and statistical models based on field data from long-term pavement performance (LTPP) database. These models are used mostly because of their capability of predicting pavement surface temperature.
