Current urban transportation options are heavily dependent on the combustion of fossil fuels even though carbon dioxide emissions (FFCO2) is known to be the largest driver of anthropogenic climate change. In this era of human-dominated influence on the environment it is important to note that climate change will have an irreversible effect on several global systems such as an increase in atmospheric and ocean temperatures, melting ice sheets, changes in precipitation patterns, rising sea levels and an alteration of the carbon cycle. (risa) With the increase in urbanization of rural areas and the expansion of cities, 50% of the earth’s population now lives in urban areas that only cover 3% of the earth’s total surface area. This is projected to increase to 70% of the world’s population in urban areas by the year 2050. These highly populated urban areas account for three-quarters of the world’s energy-related FFCO2 emissions. (Risa). There have been attempts to cross over to more sustainable fuel options to decrease the amount of fossil fuels being burned, however the actions will not be sufficient unless there is a reduction in the amount of vehicles on the road. (tolga).
In countries such as the United States the amount of vehicles on the roadways has tripled from 1969 to 2009 and in order to mitigate traffic congestion the federal and local governments spent 209 billion dollars in 2007, 218 billion dollars in 2008, and 160 billion dollars in 2009 to maintain and improve…
