EU Projects
WP 2: Characterisation & classification methodologies

Started : January 2000	Duration : 36 months
Leader	AEA Technology Rail BV
Participants	European Rail Research Institute French National Railways Psi-A Kalivoda Consult TNO Institute of Applied Physics Politecnico di Torino Institute of Sound and Vibration Research

Objectives:

To provide methodologies for describing different types of railway track and vehicles separately.
To propose an appropriate classification system for trains and track types.

Tasks:

To develop and validate the measurement and calculation tools needed in the various methodologies.
To look at both available data and data from campaigns to be carried out in the project, for the following purposes :
- To demonstrate a harmonised data structure.
- To demonstrate the measurement methods and their consistency with the calculation tools.
- To propose the classification system.
To develop approaches to measurement and classification.
To agree general methodology.
To design a structure containing all data gathered in the framework of the project.
To develop characterisation and separation tools.
To analyse the data and hereby quantify the new classification system.

Output:

Reports containing results or descriptions of techniques.
A database containing train and track noise data from each participating country with analysis and assessment.
A proposal for a classification system: a preliminary proposal at the start of the project, an intermediate proposal at mid-term and a definitive proposal at the end of the project.
