From April 18 2007, this project has been implemented and the scheduled progress has been achieved. The following is the brief presentation of primary achievements: First, the latest applicable specifications and codes widely used in EU and USA, and the information regarding the making of urban noise maps that have been carried out in EU countries, USA and Asia cities were collected for data summarization. The status of implementation in these countries is presented here in terms of the difficulties during the implementation, features of the implementation and its advantages and drawbacks as well for the reference of EPA and fellow environmental protection agencies in future operations. Secondly, make a brief description of common Urban Noise Mapping software in our country. Also, the methods of data conversion for major factors of influence, such as road noises, buildings, and noise meas urement, are provided. At the same time, the project is described the costs and benefits analysis of implement Noise Mapping and provided the noise control policy and noise mapping plans. Next, the project had been finished 50 points environmental noise monitoring, each points has monitored for 24 hours, as input source data for noise mapping used. Then, a practical noise map making and planning was carried out at a south Kaohsiung area. In this project, a 2D simulation urban noise map was carried out on a n area of 111 km2 of North Kaohsiung and an area of 245 km2 in all Kaohsiung City and 3D simulation of 10 km2 in Kaohsiung City. Including Ciangjhen; Lingya; Cining and Sianogang etc., district. The simulation software LIMA was introduced in the urban noise map simulation based on several scenarios, including freeways, expressways, regional roads, major city roads, general city road s, all roads and city blocks with buildings. Moreover, the simulation has incorporated variety of parameters, for example, daytime noise level(Ld), evening noise level(Le), nighttime noise level (Ln),all day equivalent continuous sound level(Leq)and day-evening- night noise level (Lden), and GIS was employed for graphic data processing. The results were summarized and posted on EPA website for the reference of local administrations. For the results of simulation executed in this project, also made the ana lysis for simulation effects, noise contour area influences, and effect of fixed receipt points. So far two noise counseling meetings have been held to present the achievement of this project, and in the meetings the relevant specifications and codes of EU regarding noise map making were introduced for exchanges of experience and suggestion and for the reference of EPA and fellow environmental agencies. Also, another conference of noise operation reviews and achievement discussion was held for the simulation results of this project.
