Prediction models currently being used for road traffic noise in apartment are equation of NIER, HW-NOISE of Korea Expressway Corporation, FHWA of United States, CRTN of United Kingdom, NMPB of France, ASJ RTN-Model 2003 of Japan and ISO 9613-1, 2 as a international standard. ISO 9613 species an engineering method for calculating the attenuation of sound during propagation outdoors in order to predict the levels of environmental noise at a distance from a variety of sources. This study, prior to investigation of every prediction methods listed above, aims to examine the model internationally standardized and to establish a reference for the prediction of road traffic noise in apartment.

The road traffic noise becomes aggravated due to the rapid increase of vehicles. It has a great effect on the dwelling environment. Therefore we investigate the characteristics and sources of the road traffic noise through grasping the status of the road traffic noise. This paper is concerned with the description of the various factors affecting the generation and propagation of outdoor traffic noise. It is particularly concerned with the mathematical interpretation of these processes and the resulting development of prediction techniques which are now broadly used for both the environment impact assessment of road traffic noise and the planning and design of roads and adjoining land use.

Noise pollution, especially road traffic noise-in terms of population exposure-has become a major problem in Seoul. However, although noise can be sensed directly, it is considered somewhat less important compared to other environmental pollutions. In this study, we chose nine districts in Seoul and distributed a questionnaire containing 23 questions in related to the awareness of noise pollution for 950 people living in Seoul. The results were analyzed according to the citizens' awareness on the whole, age, occupation, and were compared to the actual noise level measured by the Seoul Metropolitan Government. The analysis of the questionnarie show that road traffic noise is considered to be the main source of noise pollution in Seoul. People think that the individual and the Seoul Metropolitan Government are most responsible for the noise reduction in Seoul, but replies only little effort is put into when asked whether one has made any personal effort to reduce noise. We have concluded that noise pollution is not considered a hazardous problem to most Seoul citizens, and that most of them seem to be used to it. Yet, specific noise reduction policies, especially road traffic noise, are expected to take effect as quality of life is pursued due to economic enhancement.

In this study, computer simulation program was using to identify the effects of road traffic noise propagation depending on the road types which are very variable in dense city. To achieve this goal, the roads should adjacent to housing complex were categorized into 7 types and propagation noise level should predicted then after simulation of noise exposure population calculation are carried out. Followings the results. First, the road types producing the higher noise level are R1, R2, R3 and R7. The lowest one is R6. And R4, R5 showed that some amount of noise level reduction. Second. the R6 road type which is tunnel shaped showed the highest noise level reduction in vertical distance gap. Last, the order of noise exposure population ratio is R1>R2>R7 and R6 showed the lowest.

This is traffic noise reducing technology with higher porosity and durability by using small aggregate in upper layer and big aggregate in lower layer utilizing RSBS modifier. We can reduce average 9dB(A) of traffic noise compare to normal pavement by double layer structure with higher durability using small gap over bigger gap. Also, it increases a porosity more than 22% with more durability by RSBS modifier.

Urban area is being continuously grown traffic volume due to diverse economic activities. Especially, the traffic noise, which occurs on the road of passing by residential district, is dropping quality of life as negative element of obstructing sleep at night. This study analyzed relationship between the officially notified land price and the traffic noise in residential district by using the estimating equation of traffic noise and GIS. As a result, the officially notified land price on a parcel of residential district along the road was indicated to be higher than a parcel where is located in other place. Even traffic noise was indicated to be higher. Accordingly, a plan is judged to be necessarily arranged that can be made appraisal of the officially notified land price, which is reflected the convenience of life and the quality of life at the same time in consideration even of traffic noise together as element of appraisal given evaluating the officially notified land price in residential district where is located in the downtown.
