LA Metro Link Union Station Noise and Vibration Consulting

The Link Union Station (Link US) project, formerly known as the Southern California Regional Interconnector Project (SCRIP), is a Los Angeles County Metropolitan Transportation Authority (Metro) project designed to meet the long-term regional rail needs at Los Angeles Union Station (LAUS) by allowing the station to function more efficiently and providing a better overall passenger experience.

HMMH conducted a noise and vibration measurement program at sensitive land uses throughout the analysis area and modeled operational and construction-related noise and vibration levels from the project. The Project included noise and vibration predictions from conventional passenger rail, high-speed passenger rail, and light rail transit vehicles. To address sound levels for passengers awaiting departures or arrivals, HMMH modeled future sound levels at the station concourse and platform areas that are planned for the project. The Environmental Impact Study (EIS) examined four build alternatives to modernize the station.
