Abstract
To reduce emissions of Greenhouse Gas (GHGs) from automobiles, real on-road emission data should be required to help policy makers establish standards for reducing GHG emissions. Since general studies on calculating CO2 emissions from transportation sources have been based on petroleum consumption data, it has been difficult to analyze spatial activities and characteristics of transportation sources. In this study, we propose a method for calculating CO2 emissions from on-road transportation sources in Seoul. We focused on CO2 emission calculation by applying real traffic flow data and analyzed base emissions from the main roads and local streets. Because the emissions were calculated using a 1 km×1 km grid cell format, these data can be applied to other compatible transportation data sets for air pollution analysis, modal shift analysis, etc in the transportation sector.
