The goal of this project is to investigate the vibration and noise characteristic and its control measures for transportation systems. The system to be investigated for the first year is the rapid rail transit system, and the existing system suitable for investigation is the Taipei Rapid Transit System. The topics to be investigate are 1.According to the type of rail, structure, train velocity, etc. select at least 25 points for noise measurement, and at least 25 points (at 2 different distances from track) for vibration measurement. 2.According to the results from noise and vibration measurement, determine the standard procedure for noise measurement. 3.From the measurement results, analysize the characteristics of noise and vibration from rapid transit system, and establishes the data base for noise and vibration measurement. 4.Collect literatures form Japan, U.S. Hong Kong, and Europe on the noise and vibration control measures for rapid rail systems. 5.According the characteristics of measured data, propose the regulations and control measures for noise and vibration from rapid rail transit system. 6.Invite government agencies related to the noise and vibration regulation from rapid rail transit system to discuss the proposed regulations from the research After carrying out six research topics mentioned above, two objectives have been accomplished. 1.Establish standard measurement procedure for noise and vibration from rapid rail transit system. 2.Propose regulations and control measures for noise and vibration from rapid rail transit system.
