TRANSIT VEHICLE NOISE EMISSION LEVELS IN YOSEMITE NATIONAL PARK
The Federal Highway Administration (FHWA) has been asked by the National Park Service (NPS) to conduct a study of alternatives to permitting automobiles within Yosemite Valley in Yosemite National Park. The FHWA Demonstration Projects Division was called upon to assist in studying the noise impact of the different strategies. This report documents the results of noise emission level tests conducted by the Demonstration Projects Division on different types of transit vehicles. This data will form the base for predictions of the time-averaged levels expected in the Park from each strategy. This report also presents the results of ambient noise measurements in several areas in the valley.
