摘要

Recent statistics from the US Department of Transportation (US-DOT) and National Highway Traffic Safety Administration (NHTSA) reveal that over half of all roadway congestion is caused by highway traffic-related incidents rather than by rush-hour traffic in big cities [2]. According to the NHTSA, congested highways are the leading cause of tens of thousands of traffic-related fatalities and preliminary predictions for 2013 anticipate a 9% increase in traffic fatalities with respect to 2012 [3]. In addition to the loss of life and property caused by traffic accidents, congestion costs the nation, year after year, over 2.9 billion gallons of wasted fuel, 5.5 billions hours of lost productivity and releases 56 billion pounds of carbon dioxide [4].
