Multi-agent transport simulation model with social network in small world

Consciousness for the environmental problem of individual trip maker is important for eco-commuting promotion. Eco-consciousness would be changed by influence of other people. Therefore, the multi-agent transport simulation model with social network in small world is developed to describe the interaction of eco-consciousness for modal shift in the study. The developed simulator consists of four interactive procedures such as the agent travel behavior model, the traffic environment model, the agent eco-consciousness alteration model and the agent eco-consciousness interaction model. The commuting mode choice is described in the agent travel behavior model. On the other hand, the carbon dioxide emission from the traffic flow on urban network is estimated in traffic environment model. Moreover, the agent updates the eco-consciousness according to the evaluation of traffic environment in the agent eco-consciousness alteration model. Furthermore, the eco-consciousness of the agent is influenced by the related agents in the agent eco-consciousness interaction model. Particularly, the relation between agents is defined based on the small world network by reference to the Watts and Strogatz model.
