BS EN 15518-1:2011 Winter maintenance equipment. Road weather information systems. Global definitions and components
Road Weather Information Systems (RWIS) are complex structures used for road maintenance decision support, which feature as a rule the following components: meteorological sensors and instruments, transmission technology, computer systems for processing, representation and storing of information, road weather forecasts and alarms, in relation to traffic control and traffic information systems and more.
With a set terminology for the components and the meteorological expressions, an attempt is made to counteract a diversity of terms and designations for identical phenomena.
BS EN 15518-1:2011 defines the "Road Weather Information Systems” (RWIS) concept for public roads and traffic surfaces.
This standard applies to the acquisition of data on weather-related road and environment conditions as well as their forecast.
This information is typically used for road maintenance and can serve other systems like traffic management, road users information, data models, etc.
