Air pollution in general, especially air pollution from road traffic in particular in Hochiminh City (HCMC) are at the alarming. Using models to simulate air quality is needed to · manage and predict the air pollution levels. Research results have prepared emission inventory of air pollutants from road traffic, industry and domestic sources in HCMC. Besides, TAPQM and FVM models were used to simulate the meteorological conditions and air quality in HCMC. Emission inventory results from road traffic show that emission from motorcycles account for a significant amount of total load of pollutant emissions from that source.

Air pollution in general especially air pollution from road traffic in particular in Hochỉminh City HCMC are at the alarming. Using models to simulate air quality is needed to manage and predict the air pollution levels. Research results have prepared emission inventory of air pollutants from road traffic industry and domestic sources in HCMC Besides TAPOM and FVM models were used to simulate the meteorological conditions and air quality in HCMC. Emission inventory results from road traffic show that emission from motorcycles account for a significant amount of total load of pollutant emissions from that source. Simulation results of air quality give better results when using emission inventory with traffic emission factors were estimated in HCMC. In addition some scenarios to reduce pollution levels in general especially air pollution from road traffic in particular show that if reduce 50 number of motorcycles private transportation and increase 10 times number of bus public transportation air quality will more improve and can reduce traffic jam. Keywords Road traffic emission inventory models scenarios. 1. Introduction Air quality model is an important tool to manage air pollution in urban areas. We can use models to predict impacts in the process of urbanization such as development of traffic network the location or expansion of residential and industrial areas i. In óur country in general and HCMC in particular the studies aim to simulate air quality was initially implemented and achieved some initial results. Typically there were several research projects at all levels and master thesis. However one major limitation in almost studies of data on the emission factors EF .
