The costs associated with traffic congestion are high and continue to rise. The 2012 Urban Mobility Report, published by the Texas A&M Transportation Institute, cites the following facts:
- The total financial cost of congestion in 2011 was $121 billion, up $1 billion from the year before and translating to $818 per U.S. commuter and 5.5 billion h in additional travel time.
- Of that $121 billion, about $27 billion represents wasted time and diesel fuel from trucks moving goods on the system.
- Fuel wasted in congested traffic reached 2.9 billion gallons— enough to fill the New Orleans Superdome four times.
- In 2012, carbon dioxide emissions attributed to traffic congestion were 56 billion pounds or about 380 pounds per automobile commuter (1).
