As urban developments are getting better everyday, so are transportation systems that are getting more convenient, Environmental Protection Administration(EPA) of Taiwan is committed to have a noise free environment and a convenient transportation system in balance, therefore efforts have been devoted to amend the noise regulations and to improve the noise measurement method. And to meet the demand from the general public, the noise regulation is also planned to be adjusted, .but the impact of the change of noise regulation is significant, therefore studies must be carried out to understand its feasibility. And this project is to conduct studies on MRT systems. In this project, cases of noise complaints with regard to traffic noise was collected first, and its remedy actions were monitored. Also noise generated by MRT and similar systems are evaluated to the review the appropriateness of noise regulation and its feasibility . And the project are carried out as follows: 1.Collecting noise complaint cases and monitor how local government handle the situation. 2.Confirm noise reduction effect on two of the approved noise improvement projects. 3.Enaluate the status of MRT System Noise Regulation. 4.Assess the feasibility of the adjustment of noise regulations of MRT systems. 5.Conducting one forum with noise experts.
