尽管石油危机的影响，交通运输部门的能源消耗仍在增加。由于交通运输部门严重依赖化石燃料，因此预计减少CO2排放以科普全球变暖将有效节能。本文从最小化出行总长度以减少交通部门能源消耗的角度出发，研究了城市交通活动与土地利用结构之间的关系。基于无交通城市的概念，即通过调整道路供给来满足交通需求，建立了两个模型。一种是人们根据目的地的人口而移动的模式，另一种是根据行程长度而移动的模式。后一个模型描述了较短通勤的偏好。在前一个模型中，得到了使总出行距离最小的最优土地利用。研究结果表明，办公区分布在中心区周围，居住区分布在郊区，与实际城市的土地利用格局相似。另一方面，后者的模型结果表明，存在最优的通勤长度偏好，导致最小化的人均出行距离的汽车。有关道路面积的结果进行了讨论，并与东京的经验数据进行了比较。
The energy consumption in transportation sector is still increasing nevertheless of the oil crises. Since transportation sector strongly depends upon fossil fuels, it is expected to be effective for energy conservation to reduce CO2 emission to cope with global warming. In this study the authors investigate the relationship between transportation activities and land use structure in urban areas from the viewpoint of minimizing total trip length to reduce energy consumption in transportation sector Two models are developed based on congestion-free city concept which means the supply of road is adjusted to satisfy the traffic. One is the model in which people move depending on the population at their destination while the other depending on the trip length. The latter model describes the preference of shorter commuting. In the former model the optimal land use to minimize total trip length is attained. The result shows that offices are allocated around the center while residential area is relatively on the suburbs, which indicates similar pattern of land use compared with actual cities. On the other hand, results of the latter model show that there exists the optimal preference of commuting length which causes minimization of the automobiles' trip length per capita. Result concerning road area is also discussed and compared with the empirical data of Tokyo.
