    Illingworth & Rodkin has conducted numerous noise studies for Type 1 highway projects throughout California, ranging from small intersection or ramp improvement projects to the construction of new highways to highway expansion projects stretching as far as 36 miles in length. We conduct field investigations, develop traffic noise models using the Federal Highway Administration approved traffic noise model (TNM), assess impact abatement/mitigation, and prepare noise study reports in accordance with the State DOT and local traffic noise analysis protocols. Additionally, we are able to aid with the selection of pavement for purposes of noise reduction.
