Contribution of automobiles is in the range of 40 to 80% of the total air pollution. The challenge facing cities is how to reduce the adverse environmental impacts and other negative effects of transportation without giving up the benefits of mobility. The dilemma becomes most pressing under conditions of rapid urban growth, which is likely to increase travel demand significantly.
