Roadway Improvements

BBA offers traffic noise assessment services for roadway improvement projects, especially those requiring Caltrans approvals.  To meet current Caltrans requirements, BBA uses the U.S. DOT Traffic Noise Model (TNM) Version 2.5 to describe traffic noise exposures.  This program allows digitizing of roadway geometry, barriers, and receiver locations for analysis of complex situations.  The TNM is routinely calibrated using on-site noise level measurements to ensure that the results reflect actual field conditions.  Additional ambient noise measurements are conducted to describe peak hour traffic noise levels.  Traffic noise impacts are evaluated in accordance with the Caltrans Traffic Noise Protocol, following the Caltrans templates.
