Route 87 HOV Lane
San Jose, CA
A high occupancy vehicle (HOV) lane was to be added to existing freeway. RGD Acoustics services included traffic noise measurements and evaluation of potential noise impacts using standards from the California Department of Transportation (Caltrans). Specifications for off-site noise mitigation measures (noise barriers) were also evaluated as part of the project.
U.S. Highway 6 & State Highway 93
RGD Acoustics was hired to develop a comprehensive noise control plan for the City of Golden, Colorado. Initial work involved quantification of noise levels throughout the City. Meetings were held with public involvement to determine appropriate noise goals for the City. Subsequent studies identified the noisiest areas in the city and focused initial efforts on noise control for the Highway 6/93 corridor through the City. City is interested in alternative noise mitigation strategies such as clear noise barriers, tunnels and large earthen berms.
