A date for Bowlby & Associates’ next FHWA Traffic Noise Model Training Course will depend on the status of FHWA’s development and release of FHWA TNM version 3.0.  It is possible that we will hold a TNM 2.5 or 3.0 class in the Spring of 2018.


If you are interested in either a TNM 2.5 or 3.0 class, please contact Ruth Rock at rrock@bowlbyassociates.com and indicate for which version.
