A life cycle simulation method focusing on the diffusions of car- And ride-sharing services and electric vehicles

Car- and ride-sharing services being increasingly used around the world have the potential to promote the diffusion of electric vehicles. Therefore, it is important to estimate environmental load changes resulting from the diffusions of car- and ride-sharing services and electric vehicles throughout vehicle life cycles. In this study, we propose a life cycle simulation {LCS) method that focuses on the diffusions of sharing services and electric vehicles. Car- and ride-sharing services diffusion influences the travel demand and changes the total number of manufactured vehicles. On the other hand, the diffusion of electric vehicles depends on policies of a targeted area and increases the number of manufactured electric vehicles. The proposal LCS method includes two-stage allocation mechanism to integrate the effects of these two types of diffusion. The results of a case study show that this method is able to handle the integrated effects of these two diffusions.
