Zusammenfassung
Traffic emission inventory by age-cohort vehicles is an effective tool for manager to identify exactly the main vehicles polluted the air in urban area. Hanoi is one of the largest cities in Vietnam, now is facing with the serious air pollution problems which is mainly contributed by transport vehicles. In this paper, we used the dynamics model to build an age-cohorts model to estimate and predict the emissions from vehicle fleet of Hanoi by the year 2040 as well as assess the effectiveness of the management measures. The results shows that motorcycles is the main traffic air pollution source of Hanoi, accounting for 98% CO emissions, 75% NOx emissions, 81% PM emissions and 98% HC emissions. Among that, the motorcycles at the age from 3 to 9 years is the largest contributors with 57,72% CO emission, 58,5% HC emission, 62,53% NOx emission, and 54,29% PM emission. It’s estimated that, up to the year 2040, motorcycles still is the majority emission source, with a proportion of about 89% CO, 63% NOx, and 69% PM emissions.
