Transportation energy consumption and emissions - a view from city of Indonesia

Abstract

The purpose of this study is to investigate fuel consumption and road emissions of the transportation sector, thus providing a potential improvement in reducing fuel consumption and emissions. A system dynamics model for road transportation was developed in this study to mimic the fuel consumption and road emission trends of the sector. With the increase of road vehicles population, it is predicted that total fuel consumption and road emission from transportation sector in 2050 will be 62 and 65 times higher than in 2013 level. The increase in the number of private vehicles plays an essential role in escalating road emissions in Padang. The model also predicts that the reduction in the number of private vehicles and integrated public transportation system can result in about 34% reduction of fuel consumption and road emission in 2050. The results provide essential information and can be used by policy makers to meet challenges of decision making to support urban development process.
