Design Criteria to Reduce Vibration and Noise in New Rapid Transit Systems.

摘要

Excessive vibration and noise may have adverse effects on the acceptance by the community of new transit networks and can affect the comfort and ridership of passengers who use the vehicle. The report presents information on current noise levels existing in urban areas,and summarizes data describing noise and vibration levels generated by different components of existing transit systems. A summary of noise and vibration criteria currently being used by some major transit operators is presented,providing a basis for developing limiting noise and vibration formulas for a variety of transportation technologies. Recommended design criteria established for operating systems are presented to assist the transportation designer in the development of criteria that satisfies local conditions. In addition,design strategies that may be used to limit the development of noise and vibration in transit system components are discussed and illustrated. (Author)
