Applying time-resolved noise maps to assess the impact of road-traffic measures on wake-up reactions in urban environments

The present study investigates the effect of traffic measures in an urban area on the wake-up reactions at nighttime of the residents in the vicinity. These measures include road blocks and speed limits along a few selected streets in a part of Berlin representing the studied area. A temporally resolved noise mapping method based on the CNOSSOS-EU directive is used to calculate the noise level at discrete locations. The number of reactions and the awakening frequency are estimated based on the metrics established in a previous study. The results show a reduction in adverse sleep disturbances leading to awakening due to the traffic restrictions during the night.
