LIFE Monza: comparison between ante and post-operam noise and air quality monitoring activities in a Noise Low Emission Zone

AbstractLIFE MONZA project (Methodologies fOr Noise low emission Zones introduction And management) aims at defining an easy-replicable method for the identification and management of theNoise Low Emission Zones(Noise LEZ), urban areas subject to traffic restrictions, usually introduced in order to ensure compliance with the air pollutants limit values, prescribed by the European Directive on ambient air quality 2008/50/EC, whose impacts and potential benefits regarding noise issues have been taken into account, tested and analysed in a pilot area of the city of Monza, located in North Italy. Noise LEZ has been established in Libertà district, introducing infrastructural interventions carried out by the municipality (top-down actions) and encouraging an active involvement of the citizens, in the definition of a more sustainable lifestyle (bottom-up actions). The analysis of potential effects on noise reduction due to the Noise LEZ can contribute to the implementation of the EU Directive 2002/49/EC, related to the assessment and management of environmental noise (Environmental Noise Directive – END), which introduces noise action plans, designed to manage noise issues and their effects, suggesting the adoption of urban and mobility planning. Noise and air quality monitoring activities have been carried out in pilot area inanteandpost-operamconditions. The monitoring methods, the measurement techniques, the analysis procedures, able to describe the effects due to Noise LEZ establishment, for both the main environmental issues are reported in this paper, as proposals to be applied in other different contexts. Results of monitoring activities highlight a reduction of noise, in term of sound pressure levels, betweenanteandpost-operam, during the day and particularly during the night period, and it is essentially due to the interventions realised. The effect of the Noise LEZ on air pollution seems to be negligible for combustion related pollutant and carbon fractions of PM, due both to the moderate spatial effects of the measures undertaken and confounding factors due to concomitant emission sources and meteorology

LIFE E-VIA - Electric Vehicle noIse control by Assessment andoptimisation of tyre/road interaction(LIFE18 ENV/IT/000201-LIFE E-VIA)

The project LIFE E-VIA aims to tackle noise pollution from road traffic noise, in a future perspective involving a consistent portion of electric and hybrid vehicles. By combining knowledge of road optimization and tyre development, it will test an optimized solution for reducing noise in urban areas and Life Cycle Cost with respect to actual best practices. The project includes three preparatory actions, consisting of state-of-the-art studies on the components implicated in the issue: the electric vehicles (EVs), the quiet pavement technologies and the tyre role in the context of EVs vs. conventional vehicles. This report refers to project action A1 and provides an overview of the concern of electric vehicles and of their noise emission. It intends to highlight the key aspects to be taken into consideration in order to achieve the most effective and relevant implementation work, in the light of the latest technical and scientific knowledge. In the shift from conventional mobility to electromobility, the present study deals with: the electric vehicle fleet characteristics, the changed driving behaviours induced by the vehicle specificities, the different noise source features with a sharp focus on rolling noise, the changes in the noise perception by the citizens and the consideration of electric vehicles in the noise prediction methods
