RSG to Lead Webinar on Meteorological Effects on Roadway Noise

Did you know that meteorology can affect the sound adjacent to highways? RSG will be leading a Transportation Research Board (TRB) webinar on September 25 titled, “Meteorological Effects on Roadway Noise.” Presenters will describe the quantitative research and public outreach materials that state highway agencies can use to screen for meteorological influences and explain the effects to the public. Presenting alongside RSG's Ken Kaliski will be Roger Wayson of AECOM, Darlene Reiter of Bowlby and Associates, and Erik Salomons of TNO. It will be moderated by Aaron Hastings of Volpe Center.

RSG Director Published in Journal of Environmental Economics and Management

RSG Director Chris Leggett’s research was published in the latest issue of the Journal of Environmental Economics and Management. The article, “Estimating the Value of Lost Recreation Days from the Deepwater Horizon Oil Spill,” describes a recreation choice model developed for the National Oceanic and Atmospheric Administration (NOAA) to assess recreation-related losses resulting from the spill.


InterNoise 2018

RSG’s Ken Kaliski will be presenting the paper “Regulating and Predicting Wind Turbine Sound in the US” at InterNoise 2018 in Chicago on August 29th. The presentation, also led Rob O’Neal and Mark Bastasch, will highlight key factors for local noise ordinances to consider, a review of various sound propagation modeling parameters for wind turbines, and a comparison of predicted values to the results of post-construction monitoring in the US.

RSG Authors National Cooperative Highway Research Program (NCHRP) Report on How Weather Affects Noise on Highways

TRB's National Cooperative Highway Research Program (NCHRP) recently published Research Report 882: How Weather Affects the Noise You Hear from Highways, which documents the meteorological effects on roadway noise propagation under different atmospheric conditions. Highway noise changes from day to day and hour to hour—not just because of variations in traffic volumes, vehicle mix, and speed, but also because of the weather. The report, authored by RSG in cooperation with Bowlby & Associates, TNO, Wyle, Northeast Wind, and Volpe Center, develops guidance to identify when atmospheric conditions should or should not be considered in noise analyses.

Tools were developed to help explain these effects to the public, including a self-paced narrated slide presentation as well as a customizable four-panel brochure. In addition, a tool was developed to help predict the frequency of favorable and unfavorable atmospheric conditions given specific airport weather data. Check out the report and download these at


7th International Conference on Innovations in Travel Modeling (ITM)

RSG is proud to sponsor the 7th International Conference on Innovations in Travel Modeling in Atlanta next week. The conference explores current models and modeling research, addressing how the industry can respond to the rapidly changing transportation environment given socio-demographic shifts in travel preferences and the integration of new modes and infrastructure, including shared mobility and automated and connected vehicles.

RSG will have nineteen presentations at the event, discussing everything from research on TNC usage to the national behavioral freight model we've been working on. Learn more at
