An evaluation of the estimation of road traffic emission factors from tracer studies

Alain Clappier, Luis Carlos Belalcazar Ceron

Road traffic emission factors (EFs) are one of the main sources of uncertainties in emission inventories; it is necessary to develop methods to reduce these uncertainties to manage air quality more efficiently. Recently an alternative method has been propo ...

Alternative techniques to assess road traffic emissions

Luis Carlos Belalcazar Ceron

Today, one of the most important environmental problems in urban areas is air pollution. According to the World Health Organization, air pollution represents a serious risk to human health in many cities of the world. Road traffic is one of the main source ...

Estimation of road traffic emission factors from a long term tracer study

Alain Clappier, Luis Carlos Belalcazar Ceron, Erika Maria Zarate Torres, Minh Dung Ho

Road traffic emissions, one of the largest source categories in megacity inventories, are highly uncertain. It is essential to develop methodologies to reduce these uncertainties to manage air quality more effectively. In this paper, we propose a methodolo ...

Air quality modelling over Bogota, Colombia: Combined techniques to estimate and evaluate emission inventories

Hubert van den Bergh, Alain Clappier, Luis Carlos Belalcazar Ceron, Erika Maria Zarate Torres

Two versions of the Emission Inventory (EI) are generated for the city of Bogota, Colombia. In the first version (EI-1), CORINAIR traffic emission factors (EFs) are used. In the second (EI-2), bulk traffic EF's calculated for the city, using in situ measur ...
