The Taiwan High Speed Rail Transportation (HSRT) has held the trial ceremony on 27 January 2005 and planned to start the formal operation in the end of 2006. Owing to the running speed of HSRT higher to an amount of 300 km/h, which is much higher than the conventional train speed, thus the environmental impact of passing-by noise and vibration (NV) generated by HSRT needs to undertake measurement at sensitive locations alongside the track during the trial stage. In the period August~October 2005 HSRT has accomplished the test running with speed 120 km/h~315 km/h between the section from Kaoshiung to Tainan. Followed this, HSRT planned the trial running between the section from Hsin-Chu to Taoyuan in March~June 2006, and finally to perform the whole line trial later than July 2006. The aim of the project is to accomplish the following four items in 2006: 1.Monitor background and passing-by NV alongside the HSRT at 78 selected sites and 11 complaint points for noise measurements and 20 selected sites for vibration measurements to establish the data base of NV of HSRT. This data base can provide a reference for drawing up the rules of NV control of HSRT. 2.Establish the identification technique of the clustering sources of NV alongside the HSRT. This technique can provide the guideline for coping with the later NV appealing events from the residents. 3.Establish the database of background environmental vibration to provide a reference for later harmonizing the appealing events. 4.Propose an amendment draft of Noise Control Standard and a recommendation standard of Environmental Vibration Level for EPA.
