Highway Traffic Noise Course (FHWA-NHI-142051)
posted December 11, 2014

The 3-day National Highway Institute (NHI) Highway Traffic Noise training course is available for hosting by public and private organizations. This course is an excellent introduction to all aspects of highway noise concepts, regulations and procedures. It is also required by many state highway agencies as part of their consultant prerequisites for conducting traffic noise studies.

Lesson modules include:

  • Basic Traffic Noise Concepts
  • Noise Legislation, Regulations and Policies
  • Noise Study Requirements
  • Noise Measurement
  • Basics of Traffic Noise Modeling
  • Application of Traffic Noise Modeling
  • Barrier Acoustical Concepts and Design
  • Highway Construction Noise
  • Public Involvement
  • Noise Study Documentation
  • Noise Compatible Planning and Development
  • Project-Related Noise Abatement

    Audio demonstrations using the FHWA Interactive Sound Information System are an important part of the learning experience. Participants also receive a comprehensive workbook and a certificate of participation and can earn Continuing Education Units.

    For more information on the course or to request hosting a session, go to the NHI course web site: Hosts guarantee payment for a minimum of 20 participants at $600 each in 2014 and $625 in 2015, including three seats available to FHWA employees and paid for by FHWA. Hosts can register participants directly and/or make any number of seats available for registration on the NHI web site.

    For more information on hosting, please contact Heather Shelsta of NHI, Mark Ferroni of FHWA and/or NHI's contractor instructor coordinator/instructor Bill Bowlby of Bowlby & Associates, Inc.

    The instructors include FHWA staff and the following NHI-certified contractors: Darlene Reiter of Bowlby & Associates, Harvey Knauer of Environmental Acoustics, Paul Burge of URS Corporation, Jim Cowan of URS Corporation, John Jaeckel of HNTB, and Judy Rochat of ATS Consulting

    Quieter Pavements Webinar
    posted August 3, 2011

    On Wednesday, August 24, 2011, from 2:00-4:00pm EDT (11:00am-1:00pm PDT), TRB (including ADC40) is sponsoring a webinar on the "Principles and Practices of Quieter Pavements". The webinar will cover a range of topics: from the fundamentals of sound and texture, to research and policy directions related to the use of quieter pavements. It will illustrate noise measurement techniques and identification of quieter pavements, and categorize the mechanisms that lead to tire-pavement noise. Approaches for incorporating quieter pavement design and construction principles into current practices will be described, along with evaluating the role of a quieter pavement among other needs including safety, durability, and cost effectiveness. To register, please visit the TRB website.

    TRB Committee on Transportation-Related Noise and Vibration
    ADC40 started out in September 1974 as a subcommittee, with a small group of highway noise researchers who were responsible for much of the work performed in the 1970's on developing a methodology for predicting highway traffic noise. Established as a full committee [initial membership] at the 54th Annual TRB Meeting in January 1975, the then designated A1F04 group held its first review of federal research and a workshop on noise prediction in September of that year. This was the predecessor to the current ADC40 summer meeting. In addition to annual meetings in Washington, D.C., summer meetings have been held since 1979 in states all around the country...
