A Life Cycle Simulation Model for Transportation System consisting of Automobile and Public Transportation

Abstract

Environmental load reductions in transportation systems are essential for a sustainable society. In this study, a life cycle simulation model was developed for a transportation system including automobiles and public transportation. Life cycle simulation is a method for evaluating an environmental load of a product through its life cycle. To focus on total transportation demand and their teardown, effects by a temporal change of population pyramid were considered. We modeled this demand change of transportation and reflected it to life cycle simulation model. A case study was conducted on the transportation system including automobiles, buses, and trains in Suita, Osaka. The total amount of CO₂ emission and total material requirement were calculated over the next 25 years.
