Abstract
Multi-agent simulation approach is suitable to describe the heterogeneity on social interaction. The commuting vehicle transaction to clean energy vehicle corresponding to the transport policy related to economic incentive is estimated with the multi-agent simulation. The proposed multi-agent simulation system consists of the social interaction model of eco-consciousness and the eco-mobility shift model. The eco-mobility shift is affected by the eco-consciousness and the social conformity effect as well as local interaction by specific familiar person in the model. The relation between commuter agents like a social network of the real world is generated with a simple algorithm by Watts et. al. The time series changes of the number of commuting vehicle transaction to clean energy vehicle are estimated by proposed multi-agent simulation.
