Abstract
Under the assumption that the society is made up of selfish individuals, the increase in social utility can be achieved by guiding the individual selfishness to be aligned with the common good rather than naively publicizing the importance of following the traffic laws or using public transportation. In this paper traffic congestion issue is explained through game theoretic approach and getting to the equilibrium point is also explained. Policy measures are regarded as altering the utility functions of transport game and their consequences are analyzed in order to get to social optimum.
