Abstract:This program plan describes a broad program for the reduction of noise and vibration in rapid transit systems, which impacts the patrons and inhabitants of the nearby commuity. An UMTA/TSC survey has provided data on the most urgent needs and state-of-the-art techniques. Demonstrations of such techniques in operational form on transit systems are described in areas of wheel squeal, concrete floating slab, wayside sound and vibration barriers, elevated structure improvements, station and tunnel acoustics, rail joints and fastenings, and yard noise abatement. The four year program described will provide outputs on the feasibility of the techniques tested and design criteria for use by the industry on existing system improvements and for specifications on new ones.
