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.
