“…Different approaches have been pursued, motivated by the fact that noise fluctuations might be important to evaluate sleep disturbance and noise annoyance [18,19]. Other recent approaches regard participatory sensing, which enables any person to take measurements using either specific measurement equipment or mobile phones [20,21]. In addition, mobile sampling could, in principle, increase temporal and spatial resolution, even with short length samples [22], in a more controlled environment than participatory sensing, since the measurement is carried out by trained people.…”

DYNAMAP, a European Life project, aims at giving a real image of the noise generated by vehicular traffic in urban areas developing a dynamic acoustic map based on a limited number of low-cost permanent noise monitoring stations. The system has been implemented in two pilot areas located in the agglomeration of Milan (Italy) and along the Motorway A90 (Rome-Italy). The paper reports the final assessment of the system installed in the pilot area of Milan. Traffic noise data collected by the monitoring stations, each one representative of a number of roads (groups) sharing similar characteristics (e.g., daily traffic flow), are used to build-up a “real-time” noise map. In particular, we focused on the results of the testing campaign (21 sites distributed over the pilot area and 24 h duration of each recording). It allowed evaluating the accuracy and reliability of the system by comparing the predicted noise level of DYNAMAP with field measurements in randomly selected sites. To this end, a statistical analysis has been implemented to determine the error associated with such prediction, and to optimize the system by developing a correction procedure aimed at keeping the error below some acceptable threshold. The steps and the results of this procedure are given in detail. It is shown that it is possible to describe a complex road network on the basis of a statistical approach, complemented by empirical data, within a threshold of 3 dB provided that the traffic flow model achieves a comparable accuracy within each single groups of roads in the network.

“…NoiseModelling was initially designed to produce environmental noise maps over large urban areas. The model has recently been coupled with the microscopic road traffic model SYMUVIA to estimate either the impact of local transportation strategies on noise dynamics (Can et al, 2019) or individual exposure at the local scale during commuting (Quintero et al, 2019).…”

In light of the growing concern about the adverse effects of noise pollution on health, a better understanding is needed of the relationships between urban transport and individual exposure. To improve the scientific community's modeling capabilities specific to this issue, we are proposing a noise exposure modeling framework that uses agent-based activity, multi-agent travel simulation and a European standardized noise emission and propagation model. Based on two open source software packages, MATSim and NoiseModelling, this framework aims to simulate the spatiotemporal distributions of daily individual activity and road traffic noise. The proposed approach makes it possible to use all the tools and methods proposed in the NoiseModelling software by importing MATSim outputs, therefore, taking full advantage of the development work carried out within the two communities. As such, it enables both characterizing the individual exposure to road traffic-related noise and investigating noise exposure inequality problems based on the attributes of individuals and their activities.

“…In many studies noise from several sources is examined (Aletta andKang, 2015, Aumond et al, 2018) as a sampling at the measurement site of real sources in the urban environment (Chew and Wu 2016). With respect to noise mapping which is based on measurements, it is necessary to perform spatio-temporal sampling (Quintero et al, 2019). Therefore, in order to improve the sampling process, the literature offers techniques for estimating long-term noise levels based on shortterm measurements (Safeer et al, 1972, Gaja et al, 2003, Quintero et al, 2018.…”

The present article is addressing the problem of street noise investigation in urban agglomeration and the simulation of protection devices against noise. Noise levels were measured in the vicinity of the national road in Bieruń, Silesia in Poland. The publication attempts to assess the acoustic climate between a roundabout and an intersection. Based on the measured noise, the acoustic mapping was made in the SoundPlan program. The range of noise impact from the examined road section was determined. Finally, two concepts of preventive measures limiting the excessive impacts on the environment were presented, along with the indication of the impact on building development, business operations as well as transport links and traffic.
