Light pollution by using spatial interpolation in Bui Vien walking street in Ho Chi Minh city

Abstract

Abstract Light pollution is a consequence of urbanization and socio-economic development. Excessive or poor use of artificial outdoor light, from electrical equipment, beacons, billboards, etc. is one of the causes of light pollution and affects people’s health. In the Bui Vien walking street area, where night economic activities take place until dawn, the excessive lighting system has affected surrounding households. The development of remote sensing as well as GIS technology, it has helped people directly and indirectly measure the level of light pollution in the night sky. In this study, we conducted investigations and measurements on roads located around the main Bui Vien street, combined with spatial interpolation method to create a light intensity distribution map. According to research results, households in the surrounding Bui Vien neighbourhood with business activities had higher levels of light pollution than the remaining households. The results of this research are a contribution to people’s awareness of the presence of light pollution and support in the arrangement of light bulbs with moderate lighting intensity in planning and urban design.
