Abstract
Advanced Traffic Control Systems (ATCS) have been used in large cities in developing countries to ease traffic congestion problems. Congestion causing poor traffic performance has negative impacts on economic productivity, environmental quality and safety. The aim of this paper is to evaluate the impact of ATCS on fuel consumptions and pollution emissions in a large city in a developing country with specific geometric and traffic behaviour. A large road network area in Bandung, Indonesia was used as a case study. Fuel consumptions and pollution emissions (CO, NOx, HC) data was obtained from combustion and emissions laboratory. The results found that the impact of ATCS on reducing fuel consumption and pollution emission is not good especially during peak periods that usually have more traffic congestion. In conclusion, the application of ATCS in the large city in a developing country is not effective to reduce traffic congestion and enhancing environmental quality.
