Abstract
As traffic flow has been worsening, congestion causes poor traffic management performance, and negative impact on economic productivity as well as environmental quality. The focus of research is to find the recent traffic's fuel consumption character in congested network, in terms of geometric, vehicles and traffic data. Survey was conducted in Bandung, representing the congested cities in Indonesia. Research finds that during last 9 years since TRRL test, average travel speed has been decreasing more than 40 percent. The analysis is developed utilizing 3 methods, driving cycle's principle, Greenwood's noise acceleration, and hydro dynamic traffic model. Commercial and private vehicles are tested, using benzene and diesel, with various engine cylinders. the output of research will give contribution for understanding behaviour of fuel consumption, from then the alternative to reduce oil consumption would be developed.
