Excessive noise exposure may present a hazard to hearing, cardiovascular and psychosomatic health. Mass transit systems, such as the Bay Area Rapid Transit (BART) system, are potential sources of excessive noise. The purpose of this study was to characterize transit noise and riders' exposure to noise on the BART system using three dosimetry metrics. We made 268 dosimetry measurements on a convenience sample of 51 line segments. Dosimetry measures were modeled using linear and non-linear multiple regression as functions of average velocity, tunnel enclosure, flooring, and wet weather conditions, and presented visually on a map of the BART system.
