COMMUNITY NOISE FROM RAPID TRANSIT SYSTEMS

The rapidly expanding problems of urban transportation have resulted in intensified activity in the development and construction of fixed-route, high speed rapid transit systems and equipment. Higher speeds and frequent passage imply more noise and annoyance than with existing or older systems and the community noise caused by such systems and vehicles is a very important factor influencing public acceptance. Through the use of modern design concepts and equipment intended to provide reduced noise and vibration, the community intrusion caused by rapid transit system vehicles can be made acceptable, can be much quieter than traditionally expected and, in fact, can present the potential both for improving the traffic and transportation system and for reducing overall community noise. The expected wayside or community noise levels for different types of transit systems have been determined using data obtained from modern operational and experimental transit vehicles. To demonstrate the relatively low noise characteristics, and the advantages of high speed rapid transit systems in terms of potential for reducing noise pollution, the expected wayside or community noise levels from the type of transit systems most likely to be constructed or operational in the near future are presented with comparisons of the airborne noise levels from other conventional types of transportation vehicles.
