Abstract:

Due to Taiwan’s population concentrate mostly in the urban region, and its annual increasing rate for the roads are far inferior to the annual increasing rate for the vehicles, resulting frequent crowd of the road traffic and the traffic jam in the city area and the city border day by day. At present, Taiwan’s Inland transportation mainstream has followed the world’s trend; mainly take the track transportation system as the Inland transportation’s main solution.Simultaneously in recent years under the call to reduce the environmental pollution, and the purpose to more efficacy to use the energy, these factors further enabled the track transportation to once again become the best solution.
In recent years the Taipei MRT systems such as the ChungHo Line Gutting station which the bored tunnel section pass through underneath the private residence, the maintenance line Chung Haw road sector, and the Panchu line Ximen station to the LongShan Temple station’s underground tunnel, along the route the affiliated authorities（TRTC） received more and more complaints from inhabitants of nearby housings regarding their disaffection about the noise pollution level that greatly affects their life quality.  Due to the growing populace environmental protection consciousness that had gained its ground day after day, the nearby residents could not endure the increasing noise because of the rapid transportation, resulting in more and more complaint cases on noise pollution in these regions.
This paper mainly aims at the study of the origin of the noise level created and caused by the application of track
transportation system in the Taipei MRT, and to carry on its evaluation, its analysis appraisal by draws up various noises documents on the track.  Thus, to find various solutions in preventing and controlling the noise level in the system by making a longterm monitoring action for the prevention purpose to reduce the noise level, and carries on the preliminary analysis to compare the monitor data, clarify and compare the proposed countermeasures and its causes their effects in theoretically and practice.  Thus, to carries on the preferable beneficial plan for the public to provide the environmental noise prevention from the track transportation system.
