As the economy developed, urban areas enlarged hastily with a sprawl phenomenon in Japan. Transportation facilities had been prepared, and a convenient and mobile society was obtained . But the urban area was far from the compact city, so trip length has been increased and much energy is wasted by transportation every day. In order to achieve a sustainable city, it is important to reduce the waste of energy. In this paper, we propose the efficiency index of urban transportation and investigate its stabilities. This index is calculated from the origin-destination traffic volume in an urban area and shows the distance resistance which transportation essentially possesses. Moreover, it is possible to compare the efficiency index of different areas, and the desirable plan of land-use in the urban area can be made clear.
