In the US, road traffic noise levels are typically estimated without including the effects of meteorology. Research shows, however, that atmospheric changes can greatly impact these levels. The Transportation Research Board-sponsored NCHRP 25-52, Meteorological Effects on Roadway Noise, documents these meteorological effects and develops best practices for managing them.
RSG Senior Director Ken Kaliski was co-author to a follow-up article published in the latest issue of Transportation Research Record. It provides further information on the data collection and includes recommendations for applying this data to future highway noise studies.
