Abstract:

The Traffic Noise Model is the FHWA's computer program for highway traffic noise prediction and analysis. TNM has been updated many times to add new content and capabilities, address different bugs, and include improved software and modeling methods.

TNM 3.2 now contains the necessary acoustics to compute both noise from normal use and operation of the roadway as well as noise from roadway construction activities and equipment. The roadway noise acoustics remain the same as in TNM 3.0 while the construction noise acoustics are based off of the results of the NCHRP 25-49 project. This version also allows filtering and sorting more data tables, improved the error message information, and fixed segmentation bugs.
