Applications of GIS for analyzing air pollution from urban road traffic(Thai)

Abstract

Traffic air pollution is an important environmental pollution, particularly in major cities such as Bangkok, Chiang Mai, Songkla, Khon Kaen, etc. The air pollutant emission of each vehicle depends on several parameters and its dispersion is quite complicated. Therefore, the prediction or estimation of traffic air pollutants is absolutely difficult. However, researchers can simulate the generation and dispersing behavior of pollutants by mathematical models, which can be used as tools for predicting air pollution when implementing the proposed traffic and transportation plans. The Geographic Information System (GIS) can store, receive queries, and analyze data, and display spatial results very well. Therefore, the application of GIS and mathematical air pollution models will help traffic and transport planners evaluate the proposed projects/plans efficiently. This paper describes the research in development of such tools for analyzing air pollution from road traffic in urban areas both from abroad and in Thailand. These can be used as guidelines for further research.
