The California High-Speed Rail Authority is responsible for building the United States’ first true high-speed train capable of traveling over 200 mph. The expected trip time from San Francisco to Los Angeles is about two hours and forty minutes. The intercity train network will also interface with commercial airports, mass transit, and the highway network. This project is funded under the American Recovery and Reinvestment Act (ARRA) and Federal Stimulus funding.

Acentech provided noise and vibration analysis that included mapping of noise exposures along the corridor of existing noise environment and future project alternatives. We advanced the state-of-art in rail analysis by using a multi-modal noise model to generate full color noise contour maps that include roadways, parking lots, and other auxiliary noise sources. We determined transfer mobility at selected locations along the corridor. We prepared a noise and vibration technical report and the noise and vibration sections of the Environmental Impact Report/Environmental Impact Statement for the 30-mile rail corridor extending from Los Angeles Union Station to the City of Anaheim where speeds will reach 125 miles per hour.

This is the first segment of the 800-mile high-speed rail network that will connect the major metropolitan centers of the Central Valley, Los Angeles, the Inland Empire, Orange County, San Diego, Sacramento, and the San Francisco Bay Area. STV Incorporated was the design engineer for this segment.
