After selecting 28 indexes, an evaluation system for social benefit of transportation in Tibet was established, and then the social benefits of aviation, highway and railway were evaluated via the Analytical Hierarchy Process (AHP) and Likert scale in this paper. According to the result, it is evident that the political significance is the most important index in the development of transportation, and there is good social benefit to develop aviation in Tibet. It is also suggested that the constructing of transportation system should be based on conditions of history, geography, and actuality in Tibet. What’s more, the development on each vehicle, combined with their characters, should be taken into account of the relative social benefit of transportation to invest and plan. In terms of the above study, it may be helpful to support a direct, macro control to construct transportation system, and achieve development between transportation and society harmoniously in Tibet.
