Winter maintenance equipment - Road weather information systems - Part 1: Global definitions and components

This European Standard 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.

Winterdienstausrüstung - Straßenzustands- und Wetterinformationssysteme - Teil 1: Allgemeine Definitionen und Komponenten

Diese Europäische Norm legt den Begriff „Straßenzustands- und Wetterinformationssysteme” (SWIS) für öffentliche Straßen und Verkehrsflächen fest. Diese Norm dient der Gewinnung von Daten in Bezug auf wetterbedingte Fahrbahn- und Umweltbedingungen sowie deren Vorhersage. Diese Informationen werden üblicherweise für den Winterdienst auf Straßen angewendet und können für weitere Systeme, wie beispielsweise Verkehrsmanagement, Informationen für Verkehrsteilnehmer, Daten-modelle usw. zweckdienlich sein.

Matériels de viabilité hivernale - Systèmes d'information météorologique routière - Partie 1: Définitions globales et composants

La présente Norme européenne définit le concept de "Système d'information météorologique routière" (RWIS)" pour les voies publiques et les surfaces réservées à la circulation.
La présente norme s'applique à l'acquisition de données météorologiques relatives aux conditions environnementales et routières ainsi qu'à leurs prévisions.
Ces informations sont, en général, utilisées pour l’entretien des routes et peuvent être utiles à d'autres systèmes tels que pour la gestion du trafic, l'information des usagers de la route, les modèles de données, etc.

Oprema za zimska vzdrževalna dela - Cestni vremensko-informacijski sistemi - 1. del: Splošne definicije in oprema

Ta evropski standard opredeljuje koncept »cestnih vremensko-informacijskih sistemov« za javne ceste in prometne površine. Ta standard se uporablja za pridobivanje podatkov o prometnih in okoljskih pogojih, povezanih z vremenom, ter njihove napovedi. Ti podatki se običajno uporabljajo za vzdrževanje cest in lahko podpirajo druge sisteme, kot so upravljanje prometa, informacije za uporabnike cest, podatkovni modeli itd.

Overview

EN 15518-1:2011 (CEN) defines the concept, global definitions and components of Road Weather Information Systems (RWIS) for public roads and traffic surfaces. As Part 1 of the EN 15518 series, this European Standard describes how weather‑related road and environmental data are acquired and prepared (including nowcasts and forecasts) to support winter maintenance, traffic management and road‑user information. EN 15518-1:2011 sets a common terminology and component breakdown to reduce ambiguity across suppliers, authorities and service providers.

Key topics

• RWIS concept and main elements: environmental sensors (fixed or mobile), processing models/algorithms, and dissemination platforms (visualization and interfaces).
• Road weather station components: typical sensor types and measured variables such as:
  • air temperature, precipitation type/amount, visibility, dew point, relative humidity, wind speed/direction, cloud cover
  • pavement temperature, subsurface temperature, surface condition (dry/wet/frozen), amount of de‑icing chemical, road surface freezing point
• Mobile and portable data acquisition: complementary mobile monitoring for spot measurements and verification of stationary sensors.
• Traffic and camera data: integration of traffic volume/typology and image analysis for surface condition monitoring and treatment verification.
• Data handling infrastructure: PCs, servers, data concentrators for collection, storage, processing and distribution.
• Models and algorithms: data fusion, site‑specific nowcasting/forecasting and decision‑support processing tailored to user needs.
• Man‑machine interface (MMI): visualization and operational tools adapted to road managers, forecasters and road users.
• Data transfer and communications: multisource transmission (Internet, satellite, radio, phone lines); requirements that transfer characteristics must not impair data usability.
• Interoperability: communication of RWIS outputs to other systems (variable message signs, on‑board navigation, traffic management).

Applications and users

EN 15518-1:2011 is practical for:

• Road authorities and winter maintenance managers for operational decision support and treatment planning.
• ITS/system integrators and equipment manufacturers specifying RWIS components and integration points.
• Meteorological and forecasting services that supply road‑specific nowcasts/forecasts.
• Traffic management centers and navigation service providers that ingest RWIS data for traveler information and safety.
• Data modelers and researchers building site‑specific pavement condition models.

Related standards

• EN 15518 series: Part 2 (recommended observation and forecast) and Part 3 (requirements on measured values of stationary equipment).
• EN 15144 (winter maintenance terminology) is referenced for related vocabulary.
