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. In addition to the architectural updates to make TNM more compatible with modern computers and operating systems, TNM 3.1 has many functional enhancements and maintains the improvements to the acoustical algorithms that were implemented with TNM 3.0.
