Application of Overlay Method in Interpreting of Traffic Noise Distribution in Land Use

Overlay studies with geographic information systems (GIS) are usually only to
describe the condition of land elevation points, and various situations in land use. The purpose
of this study was to analyze the intensity of noise in various types of land use and visualization
of noise distribution maps. The research method uses a mathematical and overlay approach. The
results showed that the average traffic flow was 1931 veh/h with a composition of motorcycle
61%, light vehicle 35%, and heavy vehicle 4%. Traffic noise level on Tuesday is 75.2 dB, while
on Sunday it is 75.5 dB. There is no significant difference in noise intensity on Tuesday and
Sunday at Ahmad Yani, MT. Haryono, Sao-Sao, and Abunawas Street. On Tuesday the highest
noise level occurs in front of the education area while on Sunday in front of the shopping area.
The intensity of noise distribution that reaches the highest land use occurs in the shopping area,
followed by the office area,
