ENVIRONMENTAL MONITORING OF AN URBAN RAILWAY

The environmental impact of a rail infrastructure during its operation is often very strong, especially in urban environments where the structure of land is more complex. This paper deals with the use of environmental monitoring as a control tool able to act on the significant parameters linked to environmental impacts. A set of standardized monitoring activities, carried out on the basis of space and time criteria, will be able to follow the development of the parameters during the whole life of the infrastructure and the results can be compared with the desired standards. The effectiveness of the monitoring depends on the possibility to relate directly the values of the parameters with the measure to be adopted in order to modify these values. The paper deals in particular with the noise and vibration impact caused by an urban section of the new Rome-Napoli railway.
