11-26 Noise Mapping of Container Terminals at the Port of Los Angeles
Noise Mapping of Container Terminals at the Port of Los Angeles
P.I. Name & Address
Noise mapping is the geographic presentation of data related to outdoor sound levels and sound exposure with associated information on impact to the affected population. A recent study on noise pollution at the port of Long Beach by (Nguyen and Khoo, 2010) supported by METRANS has revealed that a noise map or a geographic view of noise shows the port authorities where current noise levels present a problem, where mitigation is needed, and where new and future development will have the greatest negative impact.
Noise emissions from various transportation modes including seaports have become a major concern to environmental and governmental agencies in recent years for the great annoyance they cause to surrounding communities (Baaj et al., 2001). The Los Angeles–Long Beach port complex is the nation's largest ocean freight hub and its busiest container port complex, with the amount of goods going through the port increasing, especially in the container division. As the container sector has the highest growth potential, the levels of noise generated by the ships, straddle carriers, cranes, forklifts, refrigerated containers, trucks and trains may present a problem. In addition, noise emitted from container terminals, at high levels and for long periods, has a negative impact on the performance of the different parties involved in the cargo handling activities at the container terminals as well as the life of the residential neighbors. The purpose of this study is to predict and model the noise of container terminals at the port of Los Angeles.
