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.

Some FHWA TNM users had experienced floating point errors for certain case runs in Version 1.0. FHWA TNM Version 1.0a corrected these errors for the most common floating point error bug. The FHWA TNM Version 1.0a is an update to the FHWA TNM Version 1.0 release package. It requires the complete release package for use.
