Air pollution results from two major sources: stationary sources such as factories, industrial units, and power plants, and mobile sources such as cars, trucks, and buses. The mobile sources, or the transportation sector, have been a major source of air pollution. The challenge now lies in improving the quality of the air we breathe without adversely affecting the mobility of the nation. Hence, it is important to explore transportation options that may result in potential air quality benefits. Intelligent Transportation Systems (ITS) constitute one such class of strategies that could have significant air quality benefits. Quantification of these benefits is therefore an important part of any ITS assessment effort and decision- making in the context of ITS deployment.In this paper we discuss about how intelligent transportation systems would reduce air pollutions and greenhouse gases that will bring us a greater world to live.
