In this project, the monitoring measurement data of noise and ground-borne vibrations have been carried out at a number of selected locations alongside the land transportation systems (LTS). Totally, the numbers of monitoring sites are:（1）10 noise-sensitive sites and 17 noise-complaint sites alongside the Taiwan High Speed Rail Transportation (HSRT); and 15 ground-borne vibration-sensitive and/or ground-borne vibration-compliant sites.（2）33 noise-sensitive and/or noise-compliant sites for the transportation systems other than the HSRT, which are 6 sites for the freeway system, 8 sites for the highway system, 2 sites for the common roads, 6 sites for the mass rapid transportation system, and 11 sites for the common railway system; in addition, 15 ground-borne vibration-sensitive and/or vibration-complaint sites alongside the remaining LTS, which are 5 sites for the highway system, 3 sites for the freeway system, 1 sites for the MRT systems and 6 sites for the common railway system. From the monitoring measurement data the noise and vibrations levels can be seen that: (1)In the 24 hours monitoring results at the 10 noise-sensitive sites, all are in compliance with the new noise control standards (NCS) of the LTS, while at the 17 noise-complaint, there are (2 or 3) sites are not in compliance with the NCS of the LTS. Amongst the 6 monitoring sites for the MRT system, there are 2 sites not in compliance with the NCS of the LTS, in which, 1 sites is owing to the exceedance of Leq,1h the other sites is owing to the exceedance, of both Leq,1h and Lmax,mean,1h. Amongst the 11 monitoring sites for the common railway system, there are 5 sites not in compliance with the NCS of the LTS, owing to the exceedance of the Lmax,mean,1h but all the monitoring sites are in compliance with the NCS for the Leq,1h. Amongst the 6 monitoring sites for the freeway system, all are in compliance with the NCS of the LTS. Amongst 8 monitoring sites for the highway system and 2 monitoring sites for the common roads, there are 2 sites are not in compliance with the NCS of the LTS due to the exceedance of the Leq,1h. (2)Base on the recommended vibration standard of JIS C1510, the vibrations of 2 sites alongside the HSRT, 2sites alongside the highway and 1 site alongside the freeway do not comply with the standard. (3)As the Noise Control Standards of the Land Transportation Systems promulgated and started to execute on January 21, 2010, some new control effect to the traffic noise has been emerged. While the new requirements encompassed in the standard are: (i) to limit the Lmax,mean,1h for the track traffic systems, and (ii) to isolate the control of the traffic noise out of the original Environmental Noise standards, and to require the operation institution to propose the noise improvement project or the noise subsidy project to attenuate the noise impact in a limited period once the traffic noise exceeding the Standard’s level. These measures arouse the transportation operation institutions to pay serious attention and action to the impact of traffic noise. Other achievements and suggestion include: (1)The prototype format of the raw data for the complaint cases and the countermeasures of traffic noise have been established in chapter 6. As time elapses and the database expands, the methodology to take the traffic noise can be viewed and emulated by each other works of the county (city) governments. (2)From the sound field simulations of the past 15 traffic noise complaint events, it show that the simulation analysis is a very important process to assess the noise improvement effects, and the precision can reach to an extent of ±3dB. (3)The model examples and remarks for the noise improvement plan and the noise subsidy plan are valuable for reference, since these are the consequences and conclusions of a number of consulting meetings, demonstration forum and committee meetings. (4)The separation process of the complex traffic noise has been verified by 6 cases. The errors are validated to be within a range of ±3dB. Nevertheless, the sound collecting cone needs further important to raise the separation precision.
