The aim of the project is to measure the passing-by noise and vibration (NV) generated by the Taiwan High Speed Rail Transportation (HSRT) and to establish the data base during trial stage. Hopefully, this data can provide control guide of NV level of HSRT. Besides, the background NV of some selected sensitive sites alongside the overall HSRT line is also measured. Later comparisons of such kind background NV with the passing-by NV, categorization of the NV from HSRT can be attained. Meanwhile, by using the characterization, identification methodology of the NV of HSRT from other clustering traffic noise sources at a sensitive point can be induced.
Even if the limited range (20km) of test section and trial speeds (30, 70 and 120 km/h) of HSRT during the execution period of the project, the environment impact of passing-by NV from HSRT is apparent. It shows that the impacts are influenced by the factors of running speed of train, background NV and measuring location etc.
Owning to the trial speed of HSRT train is far less than 300 km/h during the execution period of the project, thus it is recommended that further measurements of the passing-by NV are worthy of keeping on undertaking by the methodology established in this project. It is helpful to understand and cope with the NV impact problem of HSRT beforehand.
