Transport system is one of the fundamental infrastructures, and a significant source of energy consumption and environmental load. Electric vehicles are expected to reduce the latter negative effects, and improve the functionality of the transport system. However, the limited driving mileage of the electric vehicles requires different electric charging system than gasoline refueling system, and the lower driving performance might potentially
cause negative effects on traffic flows. An electric charging behavior model is developed and the efficiency in battery
capacity usage is investigated in this study. We also developed a simulation system to investigate electricity demand distribution across time of day and space within urban area considering charging behavior of electric vehicles. In addition, the effects of introducing electric micro-cars into traffic are investigated by microscopic traffic
simulations considering lower maximum speed of the micro-cars. These modeling and simulation tools enable rigorous evaluations of future transport system.
