APPLICATION OF GEOLOGICAL INFORMATION SYSTEM IN THE MANAGEMENT OF NOISE POLLUTION IN URBAN (Case study of Binh Duong Boulevard section in Thu Dau Mot City)

Abstract

The study was conducted to assess the level of noise pollution from traffic activities in urban areas (in the case of Phu Hoa Ward, Thu Dau Mot City) with the specific goal of system application Geographic information system (GIS) in developing noise pollution distribution maps in the study area. The research team collected noise data at peak hours and normal hours of weekdays and weekends with noise meters at 176 survey points. Noise measurement data is then interpolated by IDW (Inverse Distance Weighting) method to assess the spatial distribution of Binh Duong Boulevard. In addition, the study also digitized the roads and houses in the study area to partition the residential areas affected by noise. The results show that the residential areas in the major roads are affected by the most noise at peak hours, while the residential areas in the small alleys have noise levels around allow. In addtion, the results also show differences in noise levels and noise time between weekdays an weekends.
