In response to resident concerns about recent and potential service changes by AC Transit buses, ATS Consulting was retained to perform noise and vibration analysis at several locations along bus routes in Berkeley. In order to develop a systematic model for predicting noise impacts along the bus routes, controlled measurements of the old and new vehicles were performed according to SAE International Standard J1470 (June 1998). Short-term and long-term noise and vibration measurements were taken at five locations along bus routes where changes had recently taken place or were proposed, and impacts were predicted using the Federal Transit Administration criteria.
