CEN/TC 256/WG 7 - Ride comfort

This standard specifies methods for quantifying the effects of vehicle body motions on ride comfort for passengers and vehicle assessment with respect to ride comfort. The effect considered is:
   discomfort, associated with relatively low levels of acceleration and roll velocity.
Other effects, not included in the standard, are associated with higher acceleration levels:
   health risk effect: physical damage and psychological deterioration.
The standard applies to passengers travelling in railway vehicles on railway lines, including main, secondary and suburban lines. This standard could be used as a guide for other railway vehicles, for example locomotives, metros, trams, etc.
The standard applies to passengers in good health.
This standard applies to measurements of motions. It also applies to simulated motions.

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.

This European Prestandard specifies a method for quantifiying th effects of carbody movements on Ride comfort for passengers ("Comfort"). This scope of the standard is limited to public railway services; the standard includes railway vehicles designated for carrying passengers travelling on railway lines,including secondarty and suburban lines; this documen can be used as a guide for other railways vehicles, for example locomotives, metros, trams, etc. This standard applies to passengers in generally good health.
