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 3.0 features a new map-based GUI for data entry and analysis and new acoustical algorithms. These enhancements will provide users with more flexibility and accuracy during the data entry process, and better visual representations during the data analysis phase of highway traffic noise studies.
