In this paper, as a follow-up PRT studies of "J. Lee & K. Kim[2]", in terms of public transportation systems, economic feasibility of PRT systems was investigated. Based on previous studies, PRT demand was estimated and the required number of PRT vehicles has been calculated and the benefit was estimated. To ensure the economic feasibility, construction cost of a PRT system should be the level of 8 billion won per km, and the annual operating costs of the PRT system construction should be approximately 4.63% level. As a result, how much to reduce PRT construction costs, depending on whether decisions are considered to be economically feasible. Thus, PRT technology development will be conducted by targeting the most lightweight and by minimizing the infrastructure and vehicles of PRT.
