|The transport system is one of the strategic factors for the sustainable development of modern cities, where environmental requirements play a key role. The main purpose of the present project is to create tools to predict vibrations and re-radiated noise in buildings due to railway traffic in tunnels. These models would then be applied and
acted upon the end-user, creating a considerable added value for the development of more sustainable urban environments. The research proposal takes handle of a comprehensive approach (analytical, numerical and experimental) to construct tools for the prediction and mitigation of vibrations and re-radiated noise induced by railway
traffic in tunnels. The knowledge developed in topic, combined with an appropriate dissemination, will provide the technical communities and decision makers with tools for the reduction of pernicious environmental impacts, allowing improving the well-being of
the communities living surrounding railway infrastructures.
