Development of a Highway Construction Noise Prediction Model

In reaction to growing public concern and complaints about construction noise, FHWA developed the Roadway Construction Noise Model (RCNM). The RCNM is based on the construction noise model developed and utilized at the Central Artery/Tunnel Project in Boston. It has since been available for use with FHWA, state, and municipal projects. The data used for the RCNM has since been used as a reference source for construction equipment noise emissions and predictions. The model itself has been used for planning and environmental assessment, construction noise mitigation plans, regulations development, and specification enforcement. However, RCNM has limitations. It uses simplified assumptions (e.g., equipment usage factors) that limit its flexibility and accuracy. In addition, the construction equipment noise database in RCNM provides only broadband Lmax A-weighted levels, the calculation of time-dependent noise metrics is done by estimation, and there is no accounting for excess attenuation provided by ground effects and air absorption losses. To ensure compliance with state, local, and project-specific noise restrictions, an improved model is needed for predicting construction noise and the effects of noise reduction efforts. The developed model will optimize noise control strategies, assist with project delivery, and help users assess public complaints. The objective of this research is to develop and validate a noise model to calculate the acoustic environment associated with highway construction equipment and activities, to accumulate a database of noise sources, and to document the appropriate applications of the model.
