The MRT system has many advantages such as short headway, punctual, efficient, economical and environmental friendly. But the most confusing problem of the MRT system is the influence of the noise and vibration to the adjacent area, which was caused by the train moving on the track. The vibration may cause resonanting of the building and operating abnormally to the equipments in the adjacent area. In order to reduce the noise and the vibration, some mitigation measures have been considered during the track design stage in recent years. Kaohsiung MRT project had been completed at September, 2008. It brings comfort and convenience to Kaohsiung citizens, but still has to face the problem of noise and vibration. This study used the field experiment to measure the vibration of elevated bridges of Kaohsiung MRT system. And comparied with the measuring result of high-speed railway and Taiwan railway. Besides, experiments in the train of Taiwan railway and Kaohsiung MRT system are also performed. So we can understand the characteristics and the influence of the vibration in these systems when the train moving on the track.
