Railway applications - Ride comfort for passengers - Measurement and evaluation

The purpose of this document is to provide methods for quantifying the ride comfort of a passenger in a rail vehicle in response to the track sections it is operated over.
The methods aim to quantify the effects of vehicle body motions on ride comfort and to make the assessment of passenger comfort predictable, repeatable, objective and meaningful.
The methods and comfort scales are validated for people of good health.
This document applies to passengers in rail vehicles operating on heavy rail networks.
This document may also be used as a guide for example on urban rail systems, but their operational routes/environments may make it difficult to comply with the requirements of the test methods.
This document applies to measurements of motions. It also applies to simulated motions. Guidance is provided on:
- which method described within the document should be used for different scenarios;
- typical values for different comfort levels;
- the application of simulation.
This document excludes health and safety issues, non-passenger carrying vehicles, vehicle homologation and safety, limit values, motion sickness, discomfort caused by accelerating and braking, design guidelines and measurement technology.

Bahnanwendungen - Fahrkomfort für Fahrgäste - Messung und Auswertung

Diese Europäische Norm legt Methoden zur Bewertung der Auswirkungen von Bewegungen des Wagenkastens auf den Fahrkomfort für die Fahrgäste und für die Fahrzeugbemessung fest.
Die hier betrachteten Auswirkungen sind:
-   Unannehmlichkeiten in Verbindung mit relativ kleinen Beschleunigungen und Rollgeschwindigkeiten.
Andere Einflüsse in Zusammenhang mit höheren Beschleunigungspegeln sind nicht in dieser Norm erfasst:
-   Gesundheitsrisiko: körperliche Behinderung und psychische Störung.
Der Anwendungsbereich ist auf den öffentlichen Eisenbahnverkehr beschränkt, die Norm umfasst Schienenfahrzeuge, die zur Beförderung von Fahrgästen ausgelegt sind, einschließlich Neben- und Vorortstrecken. Sie kann aber auch als Leitfaden für andere Eisenbahnfahrzeuge, z. B. Lokomotiven, U Bahnen und Straßenbahnen usw. verwendet werden.
Diese Norm bezieht sich auf Fahrgäste, die sich in einem gesundheitlich guten Allgemeinzustand befinden.
Sie gilt für Bewegungsmessungen, kann aber auch für Simulationen angewendet werden

Applications ferroviaires - Confort de marche des voyageurs - Mesurage et évaluation

La présente Norme européenne spécifie des méthodes de détermination des effets des mouvements de la caisse sur le confort de marche des voyageurs et d’évaluation du véhicule du point de vue du confort de marche. L’effet considéré est :
-   l’inconfort, lié à des niveaux d’accélération et une vitesse de roulis relativement faibles.
Les autres effets, non couverts par la présente norme, sont liés à des niveaux d’accélération plus élevés :
-   risques pour la santé : Dommages physiques et psychologiques.
L’objet de la présente norme se limite au service ferroviaire public ; la norme concerne les véhicules ferroviaires de transport de voyageurs sur des lignes ferroviaires, incluant les lignes secondaires et les lignes de banlieue. Le présent document peut toutefois être utilisé comme guide pour d’autres véhicules ferroviaires comme par exemple les locomotives, les métros, les tramways, etc.
La norme s’applique à des voyageurs en bonne santé.
La présente norme s’applique aux mesurages des mouvements, mais elle peut également être utilisée pour des simulations.
