BS EN 15518-3:2011 Winter maintenance equipment. Road weather information systems. Requirements on measured values of stationary equipments
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.
Stationary equipment performs the acquisition of road and meteorological information at a fixed location.
This part of EN 15518 lays down the requirements for the recommended components of a stationary equipment of a RWIS. In the description of requirements a distinction is made between the components forming a basis stationary equipment for winter use and the recommended complementary components.
The aim is to ensure extensive combination and interchangeability within the systems.
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 15518-3:2011 specifies the terminology and performance requirements for all components of stationary equipment within a Road Weather Information Systems (RWIS).
