ITS Impact On Traffic Congestion And Environmental Quality In Large Cities In Developing Countries

Abstract

Intelligent Transportation Systems (ITS) are advanced technologies that have been used in large cities in developing countries to reduce traffic congestion and then increase environmental quality. Congestion causing poor traffic performance has negative impacts on environmental quality. The aim of this paper is to evaluate the impact of ITS implementation on reducing traffic congestion and increasing environmental quality, in term of fuel consumptions and pollution emissions (CO, NOx, HC) in large cities in developing countries with specific geometric and traffic behaviour. A number of ITS implementation in many large cities in developing countries is presented in this study. The results found that the impact of ITS implementation on reducing traffic congestion and increasing environmental quality is not always good especially during peak periods that usually have high traffic congestion.
