...odels will be enhanced with new fundamental features: the integration of the low frequency noise emission and of the actual wheel rail contact conditions for more accurate predictions of the noise emitted by the track. On-board monitoring systems will be developed to make it possible to use the real roughness values and track decay rate values measured directly at the track location where maintena ...
