Energy consumption in transportation sector is one of the targets to reduce CO_2 emission because it strongly depends on the fossil fuels and it is increasing even now while consumption in industrial sector is rather stable after the oil crises. To investigate the possibility of energy conservation in regional planning this study aims at modeling regional structure of cities and analyzing optimal number of cities from the viewpoint of minimal transportation-related energy consumption which includes not only energy for transporting but also energy for constructing roads or railways. The model takes only commuting and business trip into account. The structure is assumed to consist of the center city and satellite cities around it. Numerical results show that there exists optimal number of satellite cities and further distance makes the population concentrate on the center city. Since satellite cities are relatively small size, cities of almost the same size imply that they are independent of each other.
