Intelligent Transportation Systems (ITS) have generated considerable enthusiasm in the transportation community due to their potential for improving roadway safety, reducing traffic congestion, and enhancing the mobility of people and goods. In addition to these benefits, ITS can play a major role in reducing criteria pollutant and greenhouse gas (GHG) emissions, as well as energy consumption. Research has shown that individual environmental-ITS applications typically provide energy and GHG emissions reductions on the order of 5% to 15%. Further, there is the potential for even greater reductions if multiple environmental-ITS programs are combined in one place.
