The Net-Zero standard was proposed by Science Based Target (SBTi) to bring the net greenhouse gas emissions to zero as global warming intensifies, and this policy is spreading worldwide. Public transportation plays an important role in eco-friendly transportation and establishing a railway-oriented public transportation system is important. Among modes of railway traffic, trams are easy to access compared with subways (a representative modes of railway transportation) and are economical because of their low construction and operation costs. If a priority signal is given to the tram operation, the scheduled speed increases; The efficiency can be further improved. The purpose of this study was to analyse how the conversion of modes to public transportation caused by tram construction can affect the atmosphere and to study how much the increase in physical activity caused by the increase in public transportation affects the reduction of disease. Dongtan New Town in Korea, where trams are scheduled to be introduced, was set as the study area, and the effect of the conversion of modes of transportation resulting from tram construction was analysed through the modal split process of the four-stage transportation demand prediction model. The analysis shows that trams will generate a 54,700 trips/d conversion to public transportation within the affected area. The benefit from air pollution reduction is 25.13×108 KRW/y.
