There are many transit modes can be chosen for urban development like rail system, bus rapid transit or bus system. But many developing countries chose the rail system with a enormous infrastructure cost. Passengers do not afford the infrastructure cost of Taipei Mass Rapid Transit), because the infrastructure cost of expanding route should be self-contained and stride forward to economic sustainable objective. In order to keep the basic right of transport for all classes of citizens, we should pay more attention on that the fare of transportation will become heavy burden for those low income people who are low affordability. This research analyzed that the relationship between reducing the MRT fare and changing of affordability of low-income people. It used the social welfare and full trip cost to judge the fairness and efficiency. The concept in this research of social welfare means the efficiency of various trips in the urban and full trip cost is one of the measures for the quantitative analysis. This research is based on these two measures to trade off the efficiency and fairness in result of public transportation policies. In recent years, the publics pay more and more attention to the global warming and climate change issues. The public transportation system is considered an effective method to release the pollution and make the environment sustainable. Relative research appeared that public transportation policy could reduce the carbon dioxide and fuel consumption to keep the environment sustainable. Although social welfare would increase if policy maker only decreased the MRT fare, but the mode split didn’t transfer to public transportation obviously. It should continue carry out another policy to compensate the finance gap of MRT from levying the tax from the users of automobile and motorcycle. In this double efficient policy, social welfare full trip costs will both decreased, but in 2031 the completed route of MRT will bring the increment of social welfare. Because the BRT system has the advantage about lower infrastructure cost and shorter construction period, it will make the performance of social welfare and full trip cost much better.
