In an effort to reduce winter road maintenance costs, agencies are using Road Weather
Information Systems (RWIS) to gain more information for application to surface transportation.
RWIS technologies consist of roadside Environmental Sensor Stations (ESS), forecasts, and
information dissemination and display interfaces. RWIS allow agencies to efficiently plan
winter maintenance routes, reduce wear on the vehicle fleet, reduce chemical, sand, and salt
usage, and provide a better level of service by applying anti-icing practices.
Until recently, agencies deployed ESS equipment and data collection procedures as independent
and isolated systems. These legacy systems were designed with the vendor retrieving data from
the field, reformatting it, and presenting it to the agency. Little or no communication took place between different vendor products or multiple jurisdictions. However, as agencies have sought to expand their RWIS networks and provide their road and weather data to all who may benefit from it, the need for RWIS integration and data sharing has grown.
