High-Precision Dynamic Traffic Noise Mapping Based on Road Surveillance Video
ISPRS International Journal of Geo-Information, 2022 High-precision dynamic traffic noise maps can describe the spatial and temporal distributions of noise and are necessary for actual noise prevention. Existing monitoring point-based methods suffer from limited spatial adaptability, and prediction model ...

Dynamic noise mapping: A map-based interpolation between noise measurements with high temporal resolution [PDF]
Applied Acoustics, 2016 Abstract Since the introduction of the Environmental Noise Directive, strategic noise mapping has been used as a tool for noise policy in many European countries. Although these strategic noise maps have their merits, they also have some shortcomings: accuracy in predicted noise levels in shielded or quiet areas is not very high, the maps fail to ...

Semantic SLAM With More Accurate Point Cloud Map in Dynamic Environments
IEEE Access, 2020 Static environment is a prerequisite for most existing vision-based SLAM (simultaneous localization and mapping) systems to work properly, which greatly limits the use of SLAM in real-world environments.

Rendering of Dynamic Road Traffic Noise Map based on Paramics
Procedia, Social and Behavioral Sciences, 2013 AbstractTraffic flow is simplified as equal-interval line source in traditional road traffic noise prediction models. The prediction results of these models are non-dynamic and can only be used to render the static noise maps. This paper performs the dynamic simulation of road traffic noise by integrating traffic micro-simulation technology, noise ...

Dynamic noise maps for Ljubljana airport
Proceedings of 10th SESAR Innovation Days, 2021 The main purpose of this research is to assess the impact of aircraft noise around an airport considering spatial and temporal variations in the population. The concept of dynamic airport noise mapping has been demonstrated on Ljubljana airport case study. Detailed population mobility information for Slovenia were retrieved from a survey.

Ensembling Multiple Radio Maps with Dynamic Noise in Fingerprint-based Indoor Positioning [PDF]
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021 Fingerprint-based indoor positioning is widely used in many contexts, including pedestrian and autonomous vehicles navigation. Many approaches have used traditional Machine Learning models to deal with fingerprinting, being k-NN the most common used one.
